黄河下游生态型引黄灌区水资源承载力研究

Study on water resources carrying capacity of ecological diversion irrigation district in the lower reaches of the Yellow River

摘要: 黄河流域生态型灌区建设是当下生态文明建设的重要组成部分，以生态型灌区水资源承载力理论为研究基础，采用模糊集对分析法对黄河下游典型引黄灌区进行水资源承载力综合评价。评价结果表明，2010—2013年大功灌区水资源承载力形势不容乐观，2014—2016年大功灌区近三分之二的区域水资源承载力形势有较大好转，直至2017年大功灌区整体水资源承载力达到承载状态。

Abstract: The construction of ecological irrigation area in the Yellow River Basin is an important part of the current ecological civilization construction. Based on the theory of water resources bearing capacity of ecological irrigation area as the research basis, the fuzzy set pair analysis method is used to comprehensively evaluate the water resources carrying capacity of typical irrigation areas in the lower Yellow River in this paper. The evaluation results show that water resources carrying capacity was not optimistic in Dagong Irrigation District from 2010 to 2013 and it witnessed a great improvement in the nearly two-thirds district from 2014 to 2016. It was until the year of 2017 that Dagong Irrigation District satisfied its overall water resources carrying capacity.
