森林覆盖率与水土保持关系研究进展

Summary of the Studies on Relation between Forest Coverage and Water and Soil Conservation

森林覆盖率是反映区域森林状况的重要指标之一,对评价森林保持水土、涵养水源、调节径流和改善森林小气候等生态功能具有重要意义。在分析国内外大量研究资料的基础上,对覆盖率高低与水土流失、区域降水之间关系的研究状况进行了综述,并探讨了今后的研究方向和趋势。

Forest coverage, as one of the most important indicators of regional forest condition, is significant for the evaluation of soil and water conservation, microclimate regulation and etc. Thus, great deal of researches on the influence of the forest coverage on soil and water losses and precipitation has been carried out all over the world. In this paper, the studies in the respect mentioned above are reviewed, and the hotspots and direction in the function research are prospected.
