提高绿水生产效率之探析

Analysis on How to Increase the Productivity of Green Water

绿水是一种通过土壤蒸发和植被蒸腾等流向大气圈的水汽蒸散流。中国的绿水资源量为3.4万亿m3,占降水资源总量的54%。现综述了绿水在陆地生态系统中的作用及影响绿水流因素,结合国外相关研究进展,给出了提高绿水生产效率的几种途径,为进一步开发利用绿水资源提供参考。

Green water is one water flow returned to atmosphere derived from soil evaporation and plants transpiration. It is estimated that the total amount of green water is approximately 3. 4 billion km^3 in China, about 54% of the total precipitation. This paper reviewed the roles of green water played in the terrestrial ecosystems and the effects influenced green water flow. Combined with foreign advanced researches in green water, several ways on how to increase the productivity of green water were given. And this article gave some references to further development and utilization of green water resources.
