Quantitative assessment of resource and environment security:A case study in mountainous areas of Southwest China

Abstract

This paper takes mountainous areas of Southwest China(Guangxi Zhuang Autonomous Region,Chongqing Municipality,Sichuan Province),Guizhou Province and Yunnan Province,which are regions bearing huge pressure of resource and environment,as the study area.According to the Pressure-State-Response model,the integrated assessment index system of resource and environment security was established.Using the entropy weight and fuzzy synthetic evaluation method,the general situation of resource and environment security of each province from 1999 to 2009 were assessed quantitatively.The results are shown as follows.(1) The integral security level of the study area was lower,though the development of resource-environment system of each province showed positive momentum.(2) Yunnan had the highest holistic resource and environment security level,followed by Chongqing,Sichuan,Guizhou and Guangxi.(3) The degree of membership curve of each province presented a convergent tendency since 2006,which indicated that the mountainous areas of Southwest China made some progress during the period of the 11th Five-Year Plan(2006~2010),but the whole region has not got rid of the development model of seeking temporary economic growth at the expense of the environment and resources.
