森林的水文效应,早为农林水利工作者和自然地理等科研工作者所重视。近年来人们在进行典型区实验观测的同时,开始注意大面积上森林植被变化对水文情势影响的观察与研究。1981年7月长江上游四川境内发生特大暴雨洪水之后,人们对森林的水文效应,特别是森林与暴雨的关系和森林的调蓄雨水、滞洪削峰作用问题更加关注,并引起了上下左右
Hydrological effects of forests, as early as the forestry and water conservancy workers and natural geography and other research workers attach importance. In recent years, people in the typical experimental observation area at the same time, began to pay attention to large areas of forest vegetation changes on the hydrological situation observed and studied. After the extraordinary storm flood in Sichuan in July 1981 in the upper reaches of the Yangtze River, people paid more attention to the hydrological effect of the forest, especially the relationship between the forest and the heavy rain, and the role of the forest in controlling rainfall and flood arrest.
