黑河中游近期治理节水效果综合评价

针对日益严峻的黑河流域生态恶化局面和日益突出的水事矛盾,2001年起黑河流域实施了近期治理工程,中游近期治理的主要任务是节水改造。黑河中游近期治理节水效果良好,除平原水库控制、喷灌以外,其他措施均达到规划要求,节水能力达2.58亿m3/a,超过了规划要求的2.55亿m3/a,实现了近期治理节水目标。选取节水效果、投资、效益、可操作性4个指标对中游节水措施的适宜性进行综合评价,结果表明中游近期治理节水目标已基本实现,节水效果较好。建议扩大治理范围,将中游其他区县纳入后期规划中,加大节水力度,真正实现全流域的水资源优化配置。

Comprehensive Evaluation of Water-Saving Effect of Recent Managements in the Middle Reaches of Heihe River

The situation of ecological deterioration and increasing water contradiction in the Heihe River basin are increasingly grim.Recent managements had been implemented since 2001.The main task of the middle reaches of Heihe River was transforming the water-saving system.By 2009,all measures have reached the requirements of planning except the spray irrigation.Water-saving capacity had reached 258 million m3 annually.This article summarizes the completion of water-saving measures,evaluates the water-saving effec...
