摘要
森林凋落物是森林中植物组分产生并归还地面,作为分解者的物质和能量来源,借以维持生态系统功能的所有有机质的总称,有着重要的生态系统功能,其中凋落物的涵养水源功能及其重要。不同林型或树种的凋落物有不同的涵养蓄水能力,且森林凋落物的涵养蓄水能力受不同因素的影响。本文对不同林型凋落物持水性研究及影响其持水能力的影响因素进行了综述,对林业建设过程中的树种选择、林型搭配、林下凋落物处理提供了科学的依据。
Forest litter is the generic terms of all organic matter from plant components and returned to the ground in the forest,as material and energy sources of disintegrator,so as to maintain the ecosystem func-tion.Water conservation function of foret litter is very important. There were different water storage capacities of litters from different forest or the trees,and the water storage capacities were influenced by different factors.This paper summarized water binding capacities of litters from different forest and influence factors to water holding capacities of litters,it provided a scientific basis for tree species selection,tree species collocation and forest litter processing in forestry construction.
