The Study Of The Ecological Environment Capacity Impact In The New Town Development And Construction

Nowadays, environmental pollution and ecological destruction threatening thedevelopment of the social economic and the people’s health living. All along, we are takingthe old road which is "treatment after pollution", but the preceding environmentalprotection is far from enough to do. Environmental issues and urban development is closelyrelated to each other, China is currently in the period called rapid urbanization, there areMetro constructions in the new city. The urbanization rate goes up continuously with thegather of the population and industry in the development area, and then the ecologicalenvironment have serious repercussions. So the limit with the capacity of the ecologicalenvironment would have to refer during the development and construction in the new city.Environmental capacity as the upper limit of human activities to affect the environment wasan important indicator used to assess the health of the city and sustainable development.With the national environmental policy adjust from the discharge of pollutants emissionscontrol to control the gross of the pollutants, the research about capacity of the environmenthas also become the basis for determining emissions. The importance of environmentalcapacity is increasing gradually emerged as the scale of production and life of the city, itcan no longer feel free to use as the "godsend", but become resources such as mineral,forest, fresh water. This paper based on this view, hit on the topics of current environmentaltrends, be consistent with a number of requirements of the scientific development concept,have research the four elements in the environmental capacity, and proposed a number ofstrategies of the environment protection in the development of the new area.This paper argues that environmental capacity is not only a purely capability of naturalpurification, but also includes the purification of human activities. Environment capacityhas six characteristics such as limited capacity, objectivity, stability, changeability,controllability, periodicity and regional. Through the research in the town planning andconstruction and its environmental characteristics, this paper holds that the developmentand construction of the town should be restricted by the region environmental capacity. Inthis paper HeShengQiao new town development in XianNing as an empirical research, to do quantitative and qualitative research respectively on areas where the land suitability, thepopulation capacity, water environmental capacity, and pollutant capacity. And then tomake corresponding urban environmental protection strategy, and used for reckoning thecity land area and the urban population as well as the industry which can be introduced intothe city. The results show that: HeShengQiao area is rich in natural resources, to be sure thecoordinated and sustainable development of the urban and natural environment, need to dofeasibility study about the urban environmental capacity in the prior development of the city,and then to further define the land, people and industry and so on each element of thecapacity and requirements in the process of developing of the city.
