摘要
结合水资源-经济社会-生态环境三大系统的特点,构建了互馈关系分析指标体系。以河南省巩义市为例,结合该地区2001—2010年的相关数据,用相关分析和回归分析的方法,对水资源-经济社会-生态环境复合系统的互馈响应关系进行了分析。结果表明:水资源系统中农业用水量和工业用水量与土地利用、土地覆被变化各指标相关系数都比较高,而生态环境系统中受水资源系统影响较大的指标为水源涵养能力和叶面积指数,受经济社会活动影响较大的指标为湿地比重、生物丰度、香农多样性指数和景观破碎度。分析结果可为水资源承载能力评价指标的优化选取提供理论支持。
Based on the characteristics of water resources,economic society and ecological environment,the index system of reciprocal relation analysis is constructed.Taking Gongyi city of Henan province as an example,based on the data from 2001 to 2010 in this area,the reciprocal relationship of water resources,economic society,and ecological environment composite system was analyzed by means of correlation analysis and regression analysis.The analysis results show that the agricultural water and industrial water use in the system of water resources is highly correlated with Land-Use and Land-Cover Change.In the ecological environment system,what greatly influenced by water resources system are water conservation ability and leaf area index,and what greatly influenced by economic and social activities are the proportion of wetland,biology abundance,Shannon's diversity index and landscape fragmentation.The results of this study can provide theoretical support for index optimization of water resources carrying capacity evaluation.
