探讨适合长江流域特点的水量分配研究框架

长江流域水资源相对丰富,但存在降水时空分布不均、自然灾害频繁、城市需水增长快、供求矛盾加剧、水污染加重、用水效率低下等水资源问题.三峡水库的建设运用,外流域调水工程的实施打破了长江原有的水平衡.保证流域水资源的合理开发利用与调配对流域社会经济的发展极其重要,了解流域本身的水资源特点和问题,研究河流生态用水,分析不同功能、不同区域的水量分配额度,提出区域社会经济发展的水量分配方案,是水资源管理的基础,也是保障流域水资源的合理调配和可持续开发利用,维护河流健康发展的需求和根本.对适合长江流域特点的水量分配研究框架进行了探讨.

Investigation on water resources allocation frame being appropriate for the characteristics of the Yangtze river

The water resources in the Yangtze basin is abundant relatively,but time-spatial distribution is uneven.In the Yangtze river basin,the nature disaster is frequent,urban water demand increases fast,water supply and demand contradiction become more violent,water pollution become serious,water use efficiency is low etc.The construction of TGP and water transfer for other basins will upset original water balance of the Yangtze river.Reasonable development,utilization and allocation of water resources in the Yangtze river basin are very important for the social and economic development in the basin.Understanding the water resources characteristics and problems in the basin,researching river ecological water use,analysing water allocation quota for different water functions and different regions,putting forward water allocation scheme for regional society and economy development are the bases for water resources management,and are also the requirement and fundamental prerequisite of reasonable water resources allocation.This paper discusses water allocation frame being appropriate for the characteristics of the Yangtze river.
