杉木凋落物对土壤生物群落结构的影响研究进展

In order to solve the problem of soil quality decline caused by a large number of continuous cultivation of Chinese fir,this paper discusses the interaction of Chinese fir litter on the abundance of soil microbial population,soil microbial community structure,soil enzyme characteristics and soil animals under the forest,and further reveals the influence of litter and soil organisms on the growth of Chinese fir,which provides certain reference for the rational management of Chinese fir plantations.At home and abroad,there are many researches on the long-term productivity maintenance of Chinese fir plantation by litter,but most of them are limited to the impact of litter input on soil.The research on the impact of Chinese fir litter on soil biological abundance,community and activity is relatively few,and it is affected by geographical location.The restoration of Chinese fir land quality depends on the mutual influence of various factors.For artificial management of Chinese fir plantation,how to avoid the singleness of Chinese fir plantation structure,increase biodiversity,and the maintenance of litter and understory vegetation on Chinese fir soil fertility,and the influence of Chinese fir litter on the multi-layer community structure of Chinese fir plantation are the main research directions in the future.
