旱涝灾害的链锁反应与水利工程管理

Chain Reaction between Drought and Excessive Rain and Management for Irrigation Works

传统的疏通泄洪、排水治涝的水利工程指导方针 ,导致地表水资源日趋匮乏 ,而全球变暖使冰雪 -固体淡水也面临消亡 .变排水工程为蓄水工程 ,恢复湿地、芦苇荡、荷塘和沼泽湖泊 ,研制地下水回灌系统 ,建立水上动植物生产基地和生活基地 ,这是在人口压力下扩大地表和地下蓄水的必然趋势 ,也是蓄水工程的首要任务 .将青藏高原之水引入塔里木河 ,利用沙漠无人区蓄水 。

The traditional irrigation works that led up the desertification are drainage works.With the global warming,plenty of ice and snow would melt and flow into sea.The human being would be faced with crisis of water resources.Keeping water resources in the continent is the most important task of irrigation in the whole world.Diversion of southern waters from Qinghai-Tibet Plateau north into the basin of the Tarim He,is a longterm plan for the carrying out the water resources utilization and eco-environmental protection simultaneously.
