水源涵养林水文生态效应研究进展

Research Advance of Water Conservation Forest's Hydrological Ecological Effects

水源涵养林是具有特殊意义的防护林,具有涵养水源、调洪削峰、净化水质和调节气候等生态服务功能。该文以过去的众多研究结论为基础,分别从水量、水文生态过程、径流泥沙和水质这4个方面的影响介绍了国内外的研究进展。从各国的研究成果看来,学者们普遍认为林冠的截留率与降水量呈紧密的负相关、与林冠的截留量恰巧相反;森林的植被可以有效地改善溪流的水质情况等。该文旨在寻找其中的科学规律,以期为森林生态环境的建设和保护提供科学依据。

Water conservation forest is a special kind of protection forests. It can protect water resources, control flooo peak, purity water quau- ty, adjust climate and so on. Based on the past research conclusion, research progress at home and abroad were introduced from aspects of water quantity, hydrological ecological process, runoff and sediment and water quality. From the national research view, scholars generally believed that the interception rate of canopy is negatively related to the precipitation, and is opposite with the canopy interception. The forest vegetation can effectively improve water quality of the stream. The study aimed to find their scientific laws and provide reference for the protection and de- velopment of the forest ecological environment.
