针对区域水资源可持续发展能力的评价问题,基于“自然-社会”二元模式,识别出了自然、社会和水资源3个因素的影响因子,构造了第一层由3个因素、第二层由21个指标组成的多层次评价指标体系,构建了基于相对差异函数的模糊可变评价模型。以开封市为研究实例进行了评价,结果显示:2012年兰考县和通许县的水资源可持续发展能力为Ⅱ级(较强),其他县(区)的水资源可持续发展能力为Ⅲ级(中等)。通过实例验证,表明该评价模型具有较好的适用性和合理性,指标的代表性和覆盖性较好,特别是针对较小的评价区域,能够有效地识别出指标差异,获得精准的评价等级。
In view of the evaluation of the sustainable development ability of regional water resources, based on the dual mode of “natural - social ”, the influential factors of natural, social and water resources are identified, and the first layer is composed of three factors, The second level is composed of 21 indicators, which is composed of 21 indicators and a fuzzy variable evaluation model based on relative difference function. The results of Kaifeng City are as follows: The results show that in Lankao County and Tongxu County in 2012, the sustainable development of water resources is Grade II (strong), and the sustainable development of other counties (districts) is Grade III (medium). The result shows that the evaluation model has good applicability and rationality, the representativeness and coverage of the index are good, especially for the smaller evaluation area, which can effectively identify the index differences and obtain the accurate evaluation level .
