摘 要: 根据“压力-状态-响应”(pressure-state-response, 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(analytic hierarchy process, 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(0.521 3~0.685 6)高于2005年的生态环境质量综合指数(0.310 8~0.475 1). 最后,对评价结果进行分析并提出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。

Abstract: In this paper, an indicator system based on pressure-state-response model (PSR) was set up, and analytic hierarchy process (AHP) was applied to determine the index weight. By using this AHP-PSR model, the ecological environmental quality of Langfang city was evaluated. The results indicated that ecological environment quality composite index (0.521 3~0.685 6) in 2010 was higher than that (0.310 8~0.475 1) in 2005. Finally, the results of evaluation were analyzed and some suggestions for improving the ecological environment were put forward, which can supply foundation to lay down the target of ecological protection and environmental regulation.
Key words: environmental engineering; AHP-PSR model; ecological environment; quality evaluation
