森林不同组分对降水的生态效应研究进展

Ecological Effects of Different Components of Forest Ecosystems on Rainfall

森林是一个复杂的生态系统,森林水文学是近年来研究的热点。大气降水作为森林生态系统养分来源之一,是目前研究森林生态系统养分循环不可或缺的因子。典型的森林生态系统一般通过乔木层、灌草层、凋落物层和土壤层等组分对降水进行分配。文中系统阐述了国内外研究者关于森林生态系统各组分对降水生态效应的研究进展,同时对森林降水中营养物质的输入和输出研究作了简述,指出目前相关研究中存在的问题和今后努力的方向,旨在为今后的研究提供参考。

Forest is a complicated ecosystem and forest hydrology has been the hot issue in recent years.Rainfall is one of the important nutrient input sources of forest ecosystems, and an integral factor in the research on nutrient cycling in forest ecosystem. Typical forest ecosystems distribute rainfall generally through different components including arbor layer, shrub layer, litter layer and soil layer. The paper reviewed the research progress at home and abroad in the ecological effects of different components in forest ecosystems on rainfall, and also summarized the research on the roles of rainwater as nutrient input and output sources to a forest ecosystem in nutrient cycling. The existing problems in current research and future research orientation were discussed with the expectation to provide a reference for the further research.
