我国森林生态系统水量调节研究综述

An Overview of Research on Forest Water Conservation in China

森林水源涵养功能受到了越来越多人的关注.研究不同水文层水量调节过程对森林水源涵养具有重要意义.本文在总结我国不同尺度森林水源涵养研究的基础上指出目前研究的主要方向:小尺度上,通过野外监测实验研究森林水量调节过程;大尺度上,利用遥感、GIS技术及水源涵养评估模型等技术评估森林生态系统水源涵养功能.研究为明确森林植被各水文层的水文作用以及不同尺度下水文过程,开发基于物理过程的水文模型及评价森林生态系统的水量调节功能提供重要基础.

More and more people begin to pay close attention to Water Conservation Function of forest. Study the regulation process of different hydrological layer and canopy interception model have an important meaning in water conservation forests. This paper summarizes the research on Water Conservation Function of Forest in Multi-Scale in our country,pointing out： in small scale,studying the hydrological processes with experimental research; in large scale,evaluating the water regulation process of forest ecosystems with remote sensing,GIS technology and the evaluation model. Provide the basis for correct evaluation on hydrological effect of the forest vegetation hydrology layers,development hydrological model based on physical processes,studying on the hydrological processes at different scales,evaluating on the water regulation process of forest ecosystems.
