城市湖泊水环境安全评价研究

以"百湖之市"的武汉市为例,应用PSR模型构建了城市湖泊水环境安全的评价指标体系,采取层次分析法对模型进行求解,并评价其安全等级,结果表明武汉市2003至2007年5年中湖泊水环境安全状况呈现不断好转的趋势,说明近年来武汉市在治理湖泊污染、保障湖泊水环境安全中所采取的一系列对策和措施是行之有效的。

Evaluation for Water Environment Security of Urban Lakes

To take Wuhan City as an example,the index system,evaluating water environment security of urban lakes,was constructed using PSR model,solved with AHP,and evaluated the safety levels.The results showed that the situation of water environment security has taken on improvement trend from 2003 to 2007 in Wuhan,which proved the countermeasures on water pollution treatment and water environment security guarantee were effective.
