Study On Environmental Planning Of Newly Built Region Of Song Bei In Harbin

In course of quest for a new pattern of urban evolvement, through the reflection on success and failure of urbanization, the strengthen of planning and construction of new city zone has became a kernel topic of urbanization decision in phase of sustainable development.This paper studies the basic theory of the environmental planning of new city zone and the aim, the guideline system, the procedure and the measure of the environmental planning. In the case of Harbin Songbei new city zone, the paper investigates and analyses its environmental quality status, and establishes the environmental protection target and relevant measure on the base of the planning of total Songbei new city zone, for improving its environmental quality step by step and making the environment and economy develop harmoniously and achieving sustainable development of economy.The research and the sample analysis for the present quality of environment were mad and the result showed that the air quality of Songbei was good and all the monitoring sites reached the second level of the ambient air quality standards except for one or two monitoring indexes beyond the limit in some sites. Some monitoring sites even accorded with the first level. However, the quality of water environment and noise environment was medium level. The main causes of the bad environment were lack of environmental protection investments and environmental measures. Moreover, other causes of it were illogical industrial structure and distribution of industry. The prediction result of population and the development indexes of economy indicate that the quality of air and water will be further execrable if we don't make necessary measures, even influence the economic development and the health of residents.In order to improve the environmental quality of Songbei, it is essential to strictly control the discharged quantities of wastes and enlarge the treatment capacity and comprehensive utilization capacity of wastes. The treatment rate and attained standard rate for discharged urban wastewater makes sure to attain 100%. The wastewater treatment plant of 200000 t/d must be built in three periods, and adding to the 100000 t/d capacity of wastewater treatment of Songpu, we must insure the water quality of the main drainage area of Songbei reach second level by 2020. We will strengthen the construction of virescence and ecologic agriculture and natural landscape ecology, and strive for making the virescence more than 5000000 m2 in course of planning. Our goal for 2020 is that all the atmosphere quality indexes are better than the second level, the treatment rate of urban domestic sewage is more than 90%, the virescence rate of urban area attains 30%, and the rate of civic living rubbish disposed harmlessly attains 100%. It is preliminary perspective that there is a good situation of economic development and environment development in Songbei.
