国内外森林水文研究现状和进展

基于国内外近几十年森林水文学的研究成果,在简要介绍森林水文研究历史的基础上,概述了森林对降水、蒸发散、径流、泥沙和水质的影响等方面的最新研究进展.从国内外的研究成果看,森林植被在涵养水源、调节径流、减少径流泥沙、改善水质等方面具有重要作用,但由于研究方法、研究尺度、森林生态系统本身的复杂性等原因,各地森林水文效应具有较大差异.因此,今后森林水文研究工作必须加强水文过程物理机制研究,对于分析评价不同地带、尺度、类型的森林水文效应具有重要意义.

A Review on Current Situation of Forest Hydrology Research and Its Advances

After a brief review on forest hydrology history in the past decades, the latest advances of forest effect on rainfall, evapotranspiration, run off, sediment and water quality, etc. were summerized. The domestic and overseas research showed that forest vegetation played a very important role in water conservation, run off adjustment, sediment decrease and water quality improvement. The forest hydrological effect varied dramatically from place to place due to different research methodologies, research scales and the complexity of forest ecosystem. Therefore, the physical mechanics of hydrological process should be stressed in forest hydrology study, which was of great importance for analyzing and evaluating forest hydrology effects in different zones, different scales and different forest types.
