Table 1. Development Status Under the leadership of the provincial party committee and the provincial government and the supervision and support of the provincial people's congress, governments at all levels in the Pearl River Delta and relevant departments, especially environmental protection departments at all levels, have done a lot of work since the implementation of the "Clear Water Project" and "Blue Sky Project" approved by the provincial government. Substantial progress has been made in pollution source control with the goal of "one control and two standards", which not only basically curbed the development trend of environmental pollution and maintained the overall stability of environmental quality, but also gradually improved the environmental quality of some cities and regions. However, on the whole, environmental pollution is still very serious, and has gradually become the main factor restricting the sustainable development of this region, and the task of environmental protection is becoming more and more urgent and arduous. (1) Present situation of environmental quality 1. Air environmental quality In the past five years, the increasing trend of soot air pollution in the Pearl River Delta has been basically controlled. The monitoring results of air environmental quality in 2000 show that the annual and daily average values of SO2, NOx, TSP and dustfall in urban air in the Pearl River Delta are 0.033 mg/m3, 0.054 mg/m3 and 0.65438+ respectively. However, the air pollution in the Pearl River Delta is still serious, changing from simple soot pollution to compound pollution dominated by production pollution and consumption pollution, and the air pollution caused by motor vehicle exhaust with excessive nitrogen oxide concentration is increasingly prominent. In 2000, among the 2 1 cities in Guangdong Province, 7 of the top 10 cities in Shunde were located in the Pearl River Delta. Acid rain pollution is still quite serious, and the annual average pH value of precipitation in the region is 4.84, among which the annual average pH value of acid rain is still low, reaching 4.60, and the frequency is as high as 53%. In addition, urban monitoring results show that volatile organic compounds pollution in the air is increasingly prominent, and some cities show signs of photochemical pollution from time to time. 2. During the Ninth Five-Year Plan period, the sewage treatment capacity was greatly improved, the deterioration trend of regional water environment was basically controlled, and the water quality of some heavily polluted river sections showed an improvement trend. In 2000, the comprehensive pollution index of urban drinking water quality in 9 prefecture-level cities and Shunde city in this area was 0.30 on average, which was 12.6% lower than 1999. Among the 23 river sections in this area, the water quality reaches the standard 15, accounting for 65.2%, an increase over the previous year. However, the water pollution in the Pearl River Delta is still very serious, and there are mutual influences and contradictions among regions. The water quality compliance rate of urban drinking water sources is low, and the annual average of all monitoring indicators of drinking water sources in the region is only Zhaoqing City. Cross-regional pollution problems are prominent, such as Shenzhen and Huizhou, Dongguan and Shenzhen, Guangzhou and Foshan, Zhongshan and Zhuhai. The pollution of some river sections flowing through the city is aggravated, and the average comprehensive pollution index is 0.96, which is 4.9% higher than 1999. Shenzhen River, Jiangmen River, Guangzhou section of Pearl River, Dongguan Canal, Qianshan River in Zhuhai and Fenjiang River in Foshan are seriously polluted. Water pollution in coastal waters can not be ignored. The routine monitoring of the coastal waters of the estuary in the region does not meet the second-class standard of seawater. Serious nitrogen and phosphorus pollution, excessive oil in many places, serious organic pollution and intensified eutrophication have caused frequent red tides in the Pearl River Estuary, and the scope and frequency of red tides have increased year by year. 3. Sound environmental quality In recent years, the ban on honking horns in cities in Guangdong Province has improved noise pollution, but the problem is still very prominent. In the composition of regional noise sources, domestic pollution sources account for 54.6%, becoming the main noise pollution sources, followed by traffic, accounting for 23. 1%, and the noise pollution problem in construction sites is also prominent. It is common that the noise monitoring value of urban traffic trunk lines exceeds the standard. Among all kinds of pollution sources, traffic is the strongest, followed by industry and construction. Noise pollution in urban functional areas is the most serious in Guangzhou and Shenzhen, with the over-standard rates of 62.5% and 60.0% respectively. The most serious noise pollution in urban areas is Foshan and Shenzhen; The road traffic noise pollution in Shenzhen is the most serious. 4. Solid Waste The treatment rate and utilization rate of industrial solid waste have been obviously improved, but a considerable amount of industrial waste has not been treated, and even some harmful industrial solid waste has not been properly treated. In 2000, the untreated industrial waste in this area reached 65,438+0,073,400 tons, including 2,647 tons of hazardous waste. The amount of domestic garbage has increased greatly, but the supporting collection and treatment facilities are insufficient, especially the harmless treatment facilities are insufficient; The pollution of fire-resistant foam lunch boxes and plastic plastic bags (commonly known as white garbage) is increasingly prominent; The safe collection and disposal of medical waste and hazardous waste is not enough. The total amount of solid waste that has not been properly treated is increasing year by year, which pollutes soil and groundwater and affects people's production and living environment. 5. Ecological Environment After ten years of greening and efforts in recent years, great progress has been made in the protection and construction of the ecological environment in the Pearl River Delta, and the greening has reached the standard in an all-round way. However, with the increase of forest coverage, urban green space is swallowed up, and planning green space is squeezed out from time to time. Moreover, the overall quality of forest ecosystem is poor, and there are many young artificial forests, which are in the fragile stage of initial construction. The proportion of Class I forests in ecological public welfare forests is low, and the average annual growth of trees is also lower than the national average. The area of nature reserves is low, and the types and regional distribution of nature reserves are unbalanced. Most of them are forest ecosystems, which are concentrated in mountainous, marine and coastal ecosystems and natural heritage ecosystems. The phenomenon of indiscriminate hunting and hunting has been repeatedly banned, the number and species of wild animals and plants have dropped sharply, and biodiversity has been seriously threatened. The agricultural ecological environment is not optimistic, the pollution of livestock and poultry breeding is becoming more and more serious, the area of soil erosion is greatly increased, the intensity of pesticide application is increasing year by year, and the level of chemical fertilizer application is higher than the national average, far exceeding the safety upper limit set by developed countries. (II) The gap between the status quo of the Pearl River Delta and the indicators of modernization From the results of environmental statistics in 2000, there is still a big gap between the comprehensive environmental indicators of cities in the Pearl River Delta and the requirements of modernization, especially Dongguan. It is a very arduous task to meet the requirements of modern environmental indicators. There are two indicators: the centralized treatment rate of urban sewage and the investment index of environmental protection. Neither index reached the standard value. The centralized treatment rate of urban sewage is only close to 70% in Zhongshan, and even lower in other cities. The environmental protection investment index shows that the environmental protection investment of each city failed to meet the requirements of improving the environment, accounting for 3% of GDP in the same period. Other indicators with large gaps are the coverage rate of nature reserves and air quality. The coverage rate of nature reserves in five cities has not reached 10%, indicating that the construction of nature reserves needs to be further strengthened. The low compliance rate of motor vehicle exhaust, the high concentration of nitrogen oxides in exhaust and the large number of urban traffic vehicles in this area are one of the reasons for the deviation of air environmental quality. (3) Cause analysis 1. Environmental protection planning lacks legal status and it is difficult to play its due guiding role. As an important part of national economic and social development planning, environmental protection planning should play an important guiding role in environmental protection work in this region. At present, the legal status of environmental protection planning is uncertain, and it lacks powerful weapons to ensure the implementation of environmental protection planning, which has not become the basis for governments at all levels and departments to carry out environmental protection work. This is one of the main reasons why the industrial layout in the Pearl River Delta region is unreasonable, polluting enterprises are everywhere, and urban environmental infrastructure is seriously lagging behind.
