摘要
我国是个贫水大国,北方严重缺水。黄河的水资源也同样如此,一方面开发利用过度,另一方面上游来水量持续减少,造成了目前黄河水资源配置中的关键矛盾是水资源总量不足,拟建大柳树灌区属严重缺水区,需借 南水北调"西线调水解决,而年分配量仅2亿m3,对开发40 0～66 67万hm2耕地是 杯水车薪";此外,黑山峡水库原规划设计的功能和作用已被上、下游水库替代,显而易见,没有理由兴建黑山峡水库。
Water resources are poor in China, especially in the North. The deficit of Huanghe water resources gross is the key problem in resource distributing due to the over-exploitation of resources on the one hand and the continually deceasing of inflow from upper reaches on the other hand. The Daliushu Irrigation Area in planning situates in seriously water-lacking region, the need of water depends on the west line of 'Diverting Water from the South to the North Project'; the only 200 million cubic meter water distributed by the engineering are far inadequate in dealing with the situation of reclaiming about 400～666.7 million hectares land. So, obviously there is no necessity to build the Heisanxia Reservoir.
