基于区位熵理论的西部地区污染行业生态环境压力分析——以西宁市为例

Analysis of Ecological Environmental Pressure of Polluting Industries in Western Region Based on Location Entropy Theory——Taking Xining City as an Example

文章以西宁市规模以上污染行业为研究对象,从青海省、全国两个层面计算2013~2017年的区位熵,并结合污染行业规模以上工业总产值份额,提出了“十三五”末期及中长期对生态环境影响较大的6个主要污染行业。最后,从“控源头-防过程-治末端-创模式”等4方面提出环境经济协调发展意见建议。

Choosing the polluted industries with a designated annual revenue of Xining as the research object,this paper calculates the location entropy from 2013 to 2017 from the aspects of Qinghai Province and the total country.Considering the industrial output of the polluted industries,six major pollution industries with a great impact on the ecological environment at the final period of the 13th Five-year Plan and the medium-long term are proposed.Finally,some suggestions for the coordinated development between the environment and economy are proposed from four aspects,including source control,process prevention,end-of-pipe treatment and mode establishment.
