生态需水的概念及其计算方法

Concept of ecological water requirement and its estimation method

论述了生态需水的概念,从生态需水量的基本原理出发,探讨了各类生态需水量计算的框架。以渭河为例,估算其多年平均河道内生态需水为39 80亿m3。并对未来生态需水研究趋势进行了展望。

The concept of ecological water requirement is presented, and the essential principles and the estimation method for ecological water requirement are discussed The framework is demonstrated by an application to the Weihe River basin, which ecological water requirement is estimated as 3980×108 m3 Some prospects of this field are also presented
