    摘要:

    提出了采用层次分析法与物元分析法相结合评价水安全的思路。基于PSR模型,选取12个反映水安全的指标,采用层次分析法确定了权重系数,建立了类型识别的物元评判模型。以新郑市为例,采用层次分析法和物元分析法,先分析2006年新郑市各指标的水安全等级水平,再对2006—2011年新郑市的水安全进行综合评价。结果表明,新郑市 2008年、2010年的水安全水平属于安全等级,2006年、2007年、2009年、2011年的水安全水平为Ⅳ级,属于不安全等级,但具有向其他等级转化的可能性。针对评价结果提出相应的对策。

    Abstract:

    The author of this paper put forward an idea of water safety assessment by adopting the analytic hierarchy process(AHP)and the matter element analysis method. Based on PSR model, selecting 12 indices that reflect water safety, and determining the weight coefficient by using AHP, a matter element evaluation model of type identification was established. Taking Xinzheng City as an example, the author firstly analyzed the water safety level of each index in 2006, and then comprehensively evaluated the water safety level from 2006 to 2011. The results show that the water safety level of Xinzheng City in the years of 2008 and 2010 belongs to the safety grade, while in the years of 2006, 2007, 2009 and 2011 belongs to the unsafe grade with the Ⅳ level of water safety. However, there are some possibilities for the water safety level transforming to other grades. Based on that, some corresponding measures were put forward.
