摘要
为计算郑州市水资源承载力,分析水资源开发利用中存在的问题,为水资源可持续利用提出建议,选取水资源可利用量和水资源需求量作为评价指标,构建评价模型,确定评价等级体系;分析现状年(2011年)并预测目标年(2020、2030年)水资源可利用量和水资源需求量,计算郑州市各行政辖区水资源承载力。结果表明:2011年郑州市水资源均呈超载状态,水资源供需缺口达到11.33亿m3。随着水资源保护及节水措施的加强,2020—2030年郑州市水资源供需矛盾整体有所缓解。受经济社会快速发展及山地地形影响,巩义市、新密市、登封市水资源供不应求,供需矛盾近期内相对较大。
The aim of the study was to evaluate water resource carrying capacity in Zhengzhou City, analyzeproblems in development and utilization of water resource and provide advice for sustainable utilization ofwater resource. Water availability and demand of water resource were chosen as indexes to build evaluationmodel and define hierarchical system. By calculating and predicting water availability and demand in thecurrent year（2011） and target years（2020, 2030）, water resource carrying capacity of each county inZhengzhou was evaluated. The results showed that water resource in Zhengzhou was overloaded in 2011. Thegap between supply and demand reached up to 1.133 billion cubic meters. Contradiction between water supplyand demand from 2020 to 2030 would be alleviated with the implementation of water conservation measures.However, water demand exceeded supply in Gongyi, Xinmi and Dengfeng County because of the rapiddevelopment of economy and society and the influence of mountain topography, meaning that severecontradiction between water supply and demand would still exist in the near future in these regions.
