Chengdu builds a national eco-city.
I. Overview of Chengdu
Chengdu is the capital of Sichuan Province, located in the hinterland of Chengdu Plain in the southwest of China. Also referred to as "Jinguan City" and "Furong City". Since ancient times, it has been a "land of plenty" where "the people are suffering from floods and droughts and do not know hunger". Chengdu has jurisdiction over 9 districts, 4 cities and 6 counties, with an area of 1.2 1.000 square kilometers and a permanent population of 1.4298 million. It is the center of science, technology, commerce and finance in the southwest of China, the hub of transportation and communication, the experimental zone of comprehensive urban and rural reform in China, the world's important electronic information industry base and the national new industrialized industrial base.
(A) profound ecological background
Chengdu has superior natural endowment and is an important part of the ecological barrier in the upper reaches of the Yangtze River. Chengdu is high in the northwest and low in the southeast. Mountains, plains and hills coexist, surrounded by Longmen Mountain and Longquan Mountain. The eastern part belongs to the basin-bottom plain of Sichuan Basin, which is the heart of Chengdu Plain. The soil is deep and fertile. Rich in water resources, there are Minjiang River, Tuojiang River and other 12 main streams and dozens of tributaries, with criss-crossing rivers, criss-crossing ditches, and dotted with reservoirs, ponds and weirs. It belongs to the subtropical humid monsoon climate zone, with mild climate, abundant precipitation, diverse natural ecological environment and rich biological resources, and the forest coverage rate is over 37%. There are unique and rare plants such as Ginkgo biloba, Davidia involucrata and Prunus armeniaca, and rare animals under special state protection such as giant panda, red panda, golden monkey and wildebeest.
(B) a solid economic foundation
Since the 11th Five-Year Plan, Chengdu has maintained an average annual economic growth rate of 14.3%, with a solid economic foundation and comprehensive strength. Now it has formed advantageous industries such as electronic information, automobile machinery, aerospace, petrochemical, photovoltaic and biomedicine, and the scale of strategic emerging industries such as new energy, new materials and biomedicine ranks first in the west. At present, Chengdu is firmly grasping the great opportunities such as the new round of western development, the national comprehensive reform pilot zone for urban and rural areas, the construction of Chengdu-Chongqing Economic Zone and Tianfu New District, and striving to shoulder the development responsibility of building the province into the "first city". Conscientiously implement the development orientation of "scientific development and leading development", thoroughly implement the overall strategy of "reform, innovation, transformation and upgrading", adhere to the "five major city strategy" of traffic first, industrial upgrading, building a boutique city, coordinating urban and rural areas and opening up the whole region, and strive to advance toward the goal of "building a core economic growth pole in the western region and building a modern international metropolis". In 20 13 years, the city achieved a regional GDP of 9108.9 billion yuan, an increase of10.2%; The fiscal revenue of local governments was 89.85 billion yuan, up by16.6%; The fixed assets investment of the whole society was 650 1. 1 billion yuan, an increase of1.4%; The total retail sales of social consumer goods was 375.29 billion yuan, up by131%; The per capita disposable income of urban residents was 29,968 yuan, and the per capita net income of farmers was12,985 yuan, increasing by 10.2% and 12.9% respectively.
(C) profound historical and cultural background
Chengdu is one of the first 24 historical and cultural cities in the State Council. It has a long and unique source of civilization and a splendid and colorful process of civilization. As early as the Enlightenment, it was the center of ancient civilization in the upper reaches of the Yangtze River, with a history of urban construction and development of more than 2,300 years. The splendid ancient Shu civilization and unique folk culture are the unique charm of Chengdu. The world heritage of "Qingcheng Mountain-Dujiangyan" attracts worldwide attention, and the stunts of "changing face" and "fire breathing" of Sichuan Opera are amazing. Jinsha Site, Wuhou Temple, Du Fu Caotang, Yongling, Wangjianglou, Qingyang Palace, Wenshuyuan, Shuming Mausoleum, Zhaojue Temple and other historical and cultural relics are scattered all over the place.
(4) Ecological creation is solid and effective.
In recent years, in accordance with the overall requirements of the CPC Central Committee to "build an ecological civilization" and the work arrangements of the provincial party committee and the provincial government to promote the construction of an ecological province in Sichuan, the Chengdu Municipal Party Committee and the municipal government have firmly established the concept of "integration of form, format, culture and ecology", and insisted on creating a national ecological city as an important carrier to promote the construction of ecological civilization, as well as an important content of "building a core economic growth pole in the western region and building a modern international metropolis", as well as changing the development mode and building an ecological civilization.
In 2007, Chengdu took the lead in launching the national eco-city construction in the province, and solidly promoted the eco-city construction through scientific planning, improving laws and regulations, deepening reform and strengthening assessment. Around the creation work, Chengdu has compiled a number of special plans, such as Chengdu Eco-city Construction Plan, Chengdu Eco-city Master Plan, Chengdu Air Quality Compliance Plan, and Chengdu Circular Economy Development Twelfth Five-Year Plan, and successively promulgated Chengdu Eco-city Protection Regulations, Chengdu Drinking Water Source Protection Regulations, Chengdu Emission Trading Management Regulations and Chengdu Air Pollution Prevention Regulations. Deepen the reform of the management system of ecological environmental protection, establish and improve the system of ecological paid use and ecological compensation, innovate the management model of grassroots environmental protection, and promote the continuous innovation of system of ecological civilization; Incorporate the key tasks of ecological environmental protection such as air pollution prevention, comprehensive management of water environment and total emission reduction into the comprehensive evaluation system of the city's economic and social development, establish a coordinated linkage mechanism of municipal departments, and fully implement "one post and two responsibilities".
With the unremitting efforts of the whole city, the quality of Chengdu's ecological environment has obviously improved, forming a benign interactive pattern of economic and scientific development, sustainable ecological optimization and simultaneous improvement of people's livelihood. It has successively won the honorary titles of national civilized city, national environmental protection model city, national sanitary city, national garden city, national forest city, water-saving city in China, and best tourist city in China, and has been rated as the most livable city in China by the Asian Development Bank, making it the fourth largest city in China after Shanghai, Hongkong and Beijing.
According to the national eco-city assessment standard, Chengdu has reached the requirements of national eco-city technology assessment. The completion of each indicator is reported as follows:
Second, the completion of eco-city construction indicators
(1) basic conditions
1, formulated the Eco-city Construction Plan, which was deliberated and promulgated by the Municipal People's Congress. National environmental protection laws, regulations and systems and local environmental protection laws and regulations have been effectively implemented.
In 2007, Chengdu took the lead in launching the construction of a national eco-city in the province. In 2009, the Municipal People's Congress deliberated and passed the Chengdu Eco-city Construction Plan (2008-20 15), and the municipal government formulated and issued the Opinions of the Chengdu Municipal People's Government on Building an Eco-city (Cheng Fu Fa [2009]13), and issued the Chengdu Eco-city Construction Plan Implementation Plan (20) It has been 20 13 years since the Municipal Environmental Protection Bureau issued the Opinions on Vigorously Promoting the Construction of Ecological Civilization Demonstration Zone, and the Municipal Environmental Protection Bureau timely compiled the Implementation Report of Chengdu Eco-city Construction Planning (2008-20 15)20 13, which started the adjustment of Chengdu Eco-city Construction Planning. In order to ensure the smooth implementation of the plan, a leading group for Chengdu eco-city construction was established. On 20 14, the leading group was adjusted, and the Chengdu Eco-city Construction Leading Group was established, with then Mayor Ge Honglin as the team leader, Vice Mayor Liu Shoucheng as the deputy team leader and responsible comrades of relevant municipal departments as members. In the process of work promotion, a good working mechanism of departmental linkage, district and county interaction and social participation has been formed, and the construction of eco-city has been rapidly promoted.
According to the core concept and basic elements of building a national eco-city, our city has successively compiled and promulgated a number of special plans or schemes for eco-environment construction, such as Chengdu Eco-city Construction Plan, Chengdu Eco-city Master Plan, Chengdu Twelfth Five-Year Plan for Environmental Protection, Chengdu Air Quality Compliance Plan, Chengdu Twelfth Five-Year Plan for Circular Economy Development and Chengdu Eco-city Construction Plan Implementation Plan, and defined the tasks. 20 13 "Regulations on the Protection of Ecological Belt Around Chengdu City" was issued in our city to protect the ecological barrier around the city. At present, the "Regulations on Ecological Protection in Chengdu" is starting the preliminary legislative work in the whole city; The Regulations on Wetland Protection in Chengdu is under legislative investigation; The Regulations on the Protection of Drinking Water Sources in Chengdu has been reviewed by the Standing Committee of the Municipal People's Congress and will be implemented on 20 15.
2, the city's governments at or above the county level, all kinds of economic development zones have independent environmental protection agencies. It is necessary to incorporate environmental protection into the performance evaluation of the leading bodies of the Party committees and governments, and establish corresponding evaluation mechanisms.
In order to strengthen the construction of environmental protection institutions in the city and strengthen the unified supervision, management and organization and coordination functions of environmental protection departments, Chengdu and its nine districts, four cities and six counties have maintained independent organizational systems. Among them, there are 1 deputy department-level environmental protection administrative departments, 9 department-level environmental protection administrative departments and 10 department-level environmental protection administrative departments. The municipal and district (city) county environmental protection bureaus are all components of the government at the same level, and the main person in charge is appointed by the Standing Committee of the People's Congress at the same level. The institutional setup, staffing, administrative law enforcement and financial management of the Municipal Environmental Protection Bureau are independent, effectively exercising the unified supervision and management functions of environmental protection. Chengdu Environmental Protection Bureau has eight directly affiliated units: Municipal Environmental Monitoring Center Station, Municipal Environmental Monitoring Law Enforcement Detachment, Municipal Environmental Protection Publicity and Education Center, Municipal Ecological Environment Research and Monitoring Institute, Municipal Environmental Engineering Evaluation Center, Municipal Environmental Protection Science Research Institute, Municipal Environmental Protection Information Center and Municipal Environmental Emergency Command and Support Center.
In order to promote the coordinated development of urban and rural ecological environmental protection work and establish a pattern of large-scale ecological construction and large-scale environmental protection management, Chengdu set up environmental protection institutions in 3 17 towns (streets) and extended them to villages (communities), and established and improved the grassroots environmental protection mechanism with the same standards in the city, which truly realized that environmental protection work was "rooted" at the grassroots level and filled the gap that environmental protection work in towns (streets) was not implemented.
Environmental protection work in Chengdu implements "one post and two responsibilities", clarifies the responsibilities of environmental protection work of various functional departments, changes the situation of "one-man show" of environmental protection departments, and forms a new mechanism of environmental protection work of "unified leadership of party committees, organization and implementation of government," one post and two responsibilities of departments ",unified supervision of environmental protection and extensive participation of society". The Municipal Party Committee and the Municipal Government successively issued the Opinions on Further Strengthening Environmental Protection and the Implementation Opinions on Further Strengthening the Key Work of Environmental Protection, which incorporated environmental protection into the major decisions and important work arrangements of the whole city. The creation of an eco-city, total emission reduction and comprehensive improvement of the atmosphere and water environment are listed as people's livelihood goals and special goals, which are decomposed into relevant municipal departments and district (city) and county governments and included in the annual target assessment and performance assessment of party and government leading cadres. All objectives and tasks were completed as scheduled, and the environmental protection target responsibility system was put in place.
3, complete the task of energy conservation and emission reduction issued by the superior government. No major environmental incidents have occurred within three years, and various environmental problems reflected by the masses have been effectively solved. Alien invasive species have no obvious impact on the ecological environment.
Chengdu firmly grasps the three main lines of "engineering emission reduction, structural emission reduction and management emission reduction", makes every effort to promote pollution reduction, accelerates the elimination of backward production capacity, and promotes energy-saving management and technological transformation of key enterprises. Successfully completed the task of reducing the total amount of major pollutants issued by the State Council and provincial governments. In 20 13 years, the emissions of chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides in Chengdu were190,000 tons, 22,000 tons, 57,000 tons and 92,000 tons respectively, down by 4.26%, 4 13%, 6.83% and/kloc year-on-year. In 20 13, the provincial government ranked second in the assessment of total emission reduction of major pollutants in cities (states), and the contribution rates of chemical oxygen demand, ammonia nitrogen and nitrogen oxides to emission reduction ranked 1 in all cities (states) in the province.
Chengdu attaches great importance to the emergency treatment of sudden environmental incidents. From 20 12 to 20 14, the city * * * handled 39 environmental emergencies. Due to the timely dispatch of police and proper disposal, there was no obvious impact on the environment and no major environmental emergencies occurred. From 20 12 to 20 14, the city * * * accepted 34,554 environmental pollution reports and complaints, all of which were promptly and effectively mediated, and the settlement rate was 100%. The people's satisfaction rate with the handling of environmental letters and visits increased steadily year by year.
Various technical measures for the prevention and control of exotic pests in Chengdu were put in place in time, which did not have a significant impact on the urban ecological environment. According to 35 alien invasive species announced by the state, Chengdu Agriculture Committee identified four species (Alternanthera philoxeroides 1 species) which have caused agricultural invasion and four species (rice water weevil, red imported fire ant, poisonous wheat and ragweed) which are potential invasive species. The Municipal Bureau of Forestry and Landscape Architecture has stepped up the basic work of quarantine registration and quarantine of origin in view of serious harmful animals and plants such as pine village nematodes, eucalyptus wasps, Solidago canadensis and dodder. At the same time, it also attaches great importance to the supervision of transportation quarantine, quarantine re-inspection and foreign introduction, and has carried out a series of special quarantine law enforcement work. Strengthen the management of units and individuals that introduce forest seeds, seedlings and other propagating materials from abroad. In recent years, the Municipal Water Affairs Bureau has carried out the prevention and control of exotic aquatic animals and plants such as Ampullaria gigas, water hyacinths, Brazilian tortoises, crocodiles, bullfrogs and scavengers, effectively controlling the water hyacinth disaster.
4. The eco-environmental quality evaluation index is among the best in the province.
20 12-20 14, Chengdu's eco-environmental quality is generally stable, and the eco-environmental status indexes are 6 1.7 and 62.9 respectively (the data of 2014 has not been published yet), and the eco-environmental status has reached a "good" level, which meets the national eco-city assessment requirements.
In recent years, Chengdu has drawn a red line for ecological protection throughout the city, strengthened the construction of green space system in the central city, optimized the layout of urban parks, increased "stamp green space" and "pocket square", accelerated the construction of backbone greenways and vigorously developed green buildings. Accelerate the construction of the ecological belt around the city, implement the rehabilitation and greening of the ecological belt around the city, and accelerate the construction of the ecological system of "six lakes and eight wetlands". Create urban ecological isolation zones, develop group-like green spaces between urban corridors, strengthen the protection of high-quality farmland and water sources, and enhance the landscape of key rivers. Protect and upgrade the ecological barriers of Longmen Mountain and Longquan Mountain, consolidate the achievements of ecological projects such as natural forest protection and returning farmland to forests, establish and improve the ecological compensation mechanism, and strengthen ecological conservation, biodiversity protection and water conservation. Actively carry out the "ecological cell" construction project and make positive progress in promoting the establishment of ecological demonstration in districts (cities) and counties. The fourth annual meeting of China Ecological Civilization Forum was successfully held in Chengdu, and a national platform for the exchange of experience in ecological civilization construction was built to fully display the achievements of Chengdu's ecological civilization construction and urban elegance. The construction of ecological environment has achieved remarkable results, and the quality of ecological environment has been continuously improved.
5. 80% counties (including county-level cities) in the city have reached the national ecological county construction index and been named; The central city passed the national environmental protection model city assessment and was named.
Since 2007, Chengdu has invested a lot of money in the comprehensive improvement of rural environment and the construction of environmental infrastructure, taking eco-industry, eco-agriculture, eco-forestry, eco-tourism and eco-culture as the basic framework to comprehensively promote the creation of national eco-counties (cities, districts). According to Chengdu's eco-city construction plan, 14 suburban counties (cities) and national eco-counties (cities, districts) will be built. As of 20 14 and 12, Wenjiang District, Shuangliu County, Pixian County, Pujiang County, qingbaijiang district, Xindu District, Xinjin County, chongzhou city and Longquanyi District of Chengdu have passed the acceptance and naming of national ecological counties (cities, districts). Pengzhou City, Dayi County, Dujiangyan City and Qionglai City have passed the technical evaluation of national ecological counties (cities, districts). In February 2005, Chengdu was awarded the title of "National Environmental Protection Model City" by the Ministry of Environmental Protection (formerly the State Environmental Protection Administration), and passed the evaluation of National Environmental Protection Model City on 20 13 and 10. Meet the assessment requirements of national eco-city.
