首发时间:2011-06-15
摘要:本文根据"压力-状态-响应"(PSR)框架模型,建立生态环境质量评价的指标体系,应用层次分析法(AHP)确定指标权重,对廊坊市生态环境质量进行评价。结果表明:2010年的生态环境质量综合指数(0.5213~0.6856)高于2005年的生态环境质量综合指数(0.3108~0.4751),最后对评价结果做了分析并提出了改善生态环境的建议,为廊坊市生态保护目标及环境规划的制定提供依据。

The Ecological Environmental Quality Evaluation of Langfang Based on the AHP-PSR Model
Abstract:In this paper, an indicator system based on the pressure-state-response model(PSR) was set up. And the analytic hierarchy process (AHP) was applied to determine the index weight. By using this AHP-PSR model, the ecological environmental quality of Langfang was evaluated. The result indicated that ecological environment quality composite index (0.5213~0.6856) in 2010 was higher than that(0.3108~0.4751) in 2005.Finally,the result of evaluation was analyzed and some suggestions about improving the ecological environment were put forward, which can supply foundation to lay down the target of ecological protection and environmental regulation .
