基于熵权模糊综合模型的重庆市水环境安全评价
Assessment of water environment security in Chongqing using Fussy Evaluation Model based on Entropy Weight Method
摘要
Abstract
Based on "Pressure-State-Response" and Multilevel Fuzzy Comprehensive Evaluation Models,with 24 environmental indicators,the assessment system of water environment security for Chongqing is established and the weight indexes in the system are calculated by entropy method.With the system,the water environment security of Chongqing is assessed.The results showed that the water safety index presented a rising trend with fluctuations during 2004-2014;the water environment security was increasing during 2004-2008 from insecure to basically secure;the water environment security during 2008-2013 was in basic security;in 2014,the security level reached the highest level of security;from 2004-2014,the water environment quality was improved gradually.In the view of pressure level,the security state was stable;in the view of state level,the security state deteriorated from basic security to extremely insecurity during 2004-2014;in the view of response level,the water environment security was upgraded from very insecure in 2004 to secure in 2014,mainly due to the substantial increase in environment protection investment and sewage treatment rate.The variation trend of response level was basically consistent with the comprehensive security.In order to further improve the water environment security of Chongqing,the government should take positive measures in environmental investment,increasing forest coverage,sewage processing rate,etc.关键词
