Calculation Of Environmental Capacity In Planning Environmental Impact Assessment

China 2002 by<the people's Republic of China environmental impact evaluation method>,enlarging the scope of the environmental impact assessment to the land use planning,regional,watershed,the construction of the sea,the development and utilization planning,industry,agriculture,animal husbandry,forestry,energy,water conservancy,transportation,urban construction and other related special planning Urban and rural planning as a comprehensive planning,wide-ranging and method has diversity,environmental impact assessment is still difficult to effectively carry out.At the same time in the study of the current planning environment impact assessment,mainly concentrated in the feasibility and importance for environmental capacity calculation in the planning environmental impact,also focus on the capacity of water environment,atmospheric environment capacity of single item analysis,such as the lack of comprehensive analysis for environmental capacity.Therefore,this research at home and abroad on the basis of literature,explains the concept of environmental capacity in planning eia,analysis planning project environmental impact assessment of the environmental capacity calculation method,the key for the water capacity,land capacity and comprehensive investigation on air capacity,and with specific planning project,lanzhou LiuQuan township of urban and rural overall planning as a case,analyzes its planning project feasibility,conflict,environmental capacity and planning are analyzed and improvement measures are put forward Research conclusions are as follows:LiuQuan township development plan,soot and carbon dioxide emissions by roughly 5.9%and 13.2%of the regional atmospheric environmental capacity,within the scope of the carry of atmospheric environmental capacity,water demands and contaminants have been more than environmental capacity;Planning agricultural land area is expected to reach 70.2%,the entire town construction area reached 13.18%,is planning to build industrial area of 10%of the entire town total area of the modernity.Atmospheric environment and meet the demand of planning,land environment and planning for demand beyond the bearing capacity of water environment,mainly for water resources demand greater than supply and serious water pollution.In view of the above major problems,this paper suggested to improve and adjust for Liuquan township development planning,including reduce the scope of planning of ecological agriculture,it is reduced to 800 from 1250 mu mu,reduce the planting of aquatic plants in ecological agriculture,to switch to Gansu characteristics of crops,such as Chinese wolfberry,so as to reduce the demand for water;At the same time,increase the planning for industrial and agricultural wastewater treatment,especially the agricultural wastewater treatment problem,change the laissez-faire attitude,through technical means to reduce the content of the water pollutants.This study theory to guide practice,on the basis of theoretical analysis,through the analysis of the specific case accounting environment capacity,the analysis of the relationship between the environmental capacity and planning,research to guide regional planning case improvement has important significance.
