层次分析法与向量模法在水环境承载力评价中的应用——以胶州市为例

Application of Analytic Hierarchy Process and Vector Norm Method in Evaluation of Water Environmental Carrying Capacity in Jiaozhou City

从社会经济、资源利用、与环境管理等角度分析了胶州市水环境承载力的主要影响因素,综合构建了胶州市水环境承载力评价指标体系。采用层次分析法和向量模法对胶州市2007~2011年水环境承载力进行了评价。结果表明,胶州市水环境承载力评价值范围为0.061~0.080,胶州市水环境承载力水平较低,总体上呈先下降后上升的趋势,其中,水资源短缺为制约胶州市水环境承载力的主要因素。

In this paper, the main influencing factors for water environmental carrying capacity in Jiaozhou City were analyzed from the perspectives of social economy, resource utilization and environmental management. An evaluation indicator system was established and applied in evaluation of the water environmental carrying capacity in Jiaozhou City from 2007 to 2011 by use of analytic hierarchy process（AHP） and vector norm method. The results indicated that the water environmental carrying capacity in Jiaozhou City was in a low level within a range of 0.061~0.080, presenting a general trend of decrease first and then increase. Water resource shortage was a key factor restricting the water environmental carrying capacity in Jiaozhou City.
