基于层次分析法的危废渣库选址的环境经济适宜性分析

环境经济适宜性是以实现保护环境的同时通过选择场址降低渣库或填埋场投资、提高经济效益为目的。利用层次分析法对危废渣库选址的各限制因素逐层分析并构造判断矩阵,计算理论权重同时进行检验,结合各比选场址的实际情况确定实际权重,并对选址的环境经济适宜性进行综合评定,最终确定环境经济最适宜场址。该方法适用于多个渣库或填埋场场址的初步选址判断,将渣库或填埋场的环境经济适宜性选址由定性分析转为定量评定,增强了环境经济选址的科学性和合理性,为后续渣库或填埋场多个比选场址的初步选址提供参考。

ANALYSIS OF THE ENVIRONMENTAL ECONOMY SUITABILITY FOR DANGEROUS WASTE REPOSITORY SITING DEPENDED ON THE ANALYTIC HIERARCHY PROCESS

the purpose of the environmental and economic suitability of environmental protection is achieved by selecting the site,while reducing investment and improving economic benefits of stores or landfills.The analytic hierarchy process(AHP)is used for all the constraints analysis of dangerous waste repository siting and constructing comparison matrix to calculate the weight at the same time tested theory,and combining the comparison sites to determine the actual weight of the actual situation,and a comprehensive assessment on appropriate siting of environmental economy is done to determine finally the most appropriate site of environmental economics.The method is applicable to determining initial locations of many dangerous waste repository or landfill sites,making the slag-store or landfill site suitability of environmental and economic analysis from the qualitative to quantitative assessment,which enhances the rationality of environmental and economic location scientifically.At the same time,it will provide reference for preliminary siting of slag stores or landfills that will be built in the future.
