摘要
根据河北省农村饮水现状和当地农村饮水安全调查数据,建立了河北省农村饮水安全指数诊断指标体系。结合基于指标相关性的客观指标权重法与基于模糊分析法的主观赋权法,以最小相对熵原理为基础计算组合权重,对河北省11个地级市的农村饮水水质、水量、供水安全以及综合安全方面进行了诊断分析。结果表明,河北省农村饮水状况总体处于较不安全水平,只有石家庄的综合安全状况达到基本安全;平原地区水质污染、山区水量不足和供水不达标问题是导致河北省农村饮水不安全的主要因素。
According to the present situation and the survey data about local rural drinking water safety of Hebei province, the system of safety index for Hebei rural drinking water was established. Combining objective weight of CRITIC and subjective weight of fuzzy analysis, combinational weights were obtained based on the principle of minimum relative entropy. Using these combinational weights, quality, quantity, supply and comprehensive security about rural drinking water of 11 prefecture-level cities in Hebei province were diagnosed. The results showed that the situation of rural drinking water in Hebei province was at a level of relative insecurity, only Shijiazhuang with comprehensive safety condition being in basic security. The problems of water pollution in plain regions, water shortage and supply in mountainous areas were obvious.
