See table 1 for the main technical and economic indicators of this project, and table 2 for the single building.

4. Analysis of industrial policy compliance and site selection rationality

Formulating and implementing the Guiding Catalogue of Industrial Structure Adjustment of National Development and Reform Commission (20 1 1, revised in 20XX) is an important measure to achieve the objectives of the Twelfth Five-Year Plan, which is of great significance for fully implementing Scientific Outlook on Development, strengthening and improving macro-control, further changing the mode of economic growth, promoting the adjustment, optimization and upgrading of industrial structure, and maintaining the steady and rapid development of the national economy.

The Twelfth Five-Year Plan period is an important period for China to build a well-off society in an all-round way. Energy, transportation, water conservancy, electricity, urban infrastructure and real estate are still the focus of China's economic development.

This project is the construction and management of affordable housing. According to the classification of the National Development and Reform Commission's Guidance Catalogue for Industrial Structure Adjustment (20 1 1, revised in 20XX), it belongs to the 37th item of the first encouraged project, and its construction conforms to the national industrial policy.

The municipal facilities where the project is located are relatively perfect, and the infrastructure such as water supply and drainage, electricity, gas, communication and central heating has been completed, and the regional environmental quality is good. The site is adjacent to urban traffic roads, and the surrounding traffic is very developed, which provides convenience for project construction, raw material transportation and travel.

To sum up, considering the regional environmental function zoning, traffic conditions and other aspects, the site selection conforms to the overall planning of Changchun City and Shuangyang District, the nature of the project construction conforms to the positioning of the land use function by the government planning department, and the site selection is reasonable.

Three. General situation of surrounding environment of construction project

This project is located in the area of Sheling Sub-district Office, Shuangyang District, Changchun City, east to the open space, west to Planning 15th Street, south to Planning 16th Road, and north to Shexinbei Line plot. The north side of the proposed residential area is the luxury New North Line, and the road is Changchun Institute of Architecture.

The west side is planned as C 15 Street, which is separated from the Happy New Town Community and 300 meters away from Changchun Tourism College. On the south side is the planned road C 16, separated by Lan Valley; The east side is the construction site of the fiscal and taxation community, and the southeast side is the fiscal and taxation community.

1, the environmental status of the area where the construction project is located.

1) Ambient air function zoning

According to the Functional Zoning of Environmental Air Quality in Changchun City, the area where the proposed project is located is the secondary area of environmental air quality.

2) surface water environmental function zoning

The water body included in this project is Sheling River. Because the Sheling River is not planned in the Functional Zoning of Surface Water in Jilin Province (DB22/388-2004), it will eventually flow into Shuangyang River, and the dam site of Shuangyang Reservoir-estuary of Shuangyang River belongs to Class III water body, so the surface water of this project is classified as Class III water body.

3) Functional zoning of environmental noise

According to the noise function zoning of Shuangyang District, the project area is 1 functional area.

2. Scope of environmental impact assessment

1) Ambient air

According to HJ 2.2-2008 Technical Guidelines for Environmental Impact Assessment, the assessment level of ambient air is mainly determined by factors such as the maximum ground concentration of air pollutants in the project.

The heating of this project is centralized heating, which does not produce coal-fired flue gas pollutants. Therefore, only the present situation of ambient air is evaluated. The evaluation scope of ambient air quality status is a circular area with a diameter of 5km centered on this project.

2) Surface water

The domestic sewage discharge of this project is 296.45m3/d, and the water pollutants are relatively simple. Through the municipal sewage pipe, it enters Changchun Shexin Sewage Treatment Plant for treatment. The sewage receiver is Sheling River and finally flows into Yongchun River. The assessment section of Yongchun River in this project is Class III water body. According to the regulations of HJ/T2. 1- 1993, the assessment level of surface water is Class III.

The evaluation range is from 0.5km upstream of the outlet of Sheling Sewage Treatment Plant in Changchun to the estuary of Shuangyang River, with a length of about 5km, and from 2km upstream to 5km downstream of the intersection of Shuangyang River and Sheling River, with a length of about 7km and a total length of about 12km. .

3) Noise

The area where this project is located belongs to the 1 class in the Standard for Sound Environmental Quality (GB3096-2008). According to the Technical Guideline for Environmental Impact Assessment (HJ 2.4-2009), the acoustic environment functional zones where the construction project is located are 1 and Class 2 in GB 3096-2008, which belong to Class II. Therefore, the acoustic environment assessment level of this project should be Grade II.

According to the requirements of Technical Guideline for Environmental Impact Assessment Acoustic Environment (HJ 2.4-2009), the scope of this assessment is 200m at the boundary of the construction project.
