河道内生态环境需水量计算方法的研究现状及其改进探讨

Discuss on the research situation of estimating methods of eco-environmental water requirements in river course and its modification

从河道内生态环境需水量的基本概念出发,提出河道内生态环境需水量的计算方法问题,认为尺度转换问题是河道内生态环境需水计算的基础;总结了目前国内外较为常用的河道内生态环境需水量的计算方法,同时对其进行了综合比较,指出了其优缺点;认为将国外和国内计算方法有机结合并进行合理改进,使之适合国内河道内生态环境需水计算,是今后国内河道内生态环境需水研究的方向之一。

Based on the basic concept of eco-environmental water requirements in river course, the question on estimation methods has been presented. The issue of scale transformation was considered the base to estimate eco-environmental water requirements in river course. Then more general estimation methods of eco-environmental water requirements in river course at home and abroad were summarized, the synthesis comparison to them was carried on, and the advantages and disadvantages of applying them to practice were pointed out. Finally, in order to estimate eco-environmental water requirements in river course in domestic, it was thought that combining domestic estimation methods with foreign estimation methods and reasonable improvement was one of research directions.
