摘要: 土壤有机质在养分循环、土壤理化性质等方面具有重要作用,是陆地生态系统重要的碳库,对全球碳素循环的平衡起着重要作用.本文详细阐述了杉木林地土壤有机质的性质与组成,杉木连栽对土壤有机质含量、腐殖质结合形态的影响以及林分发育过程中土壤有机质的变化,炼山、整地、施肥等经营活动对杉木林地土壤有机质的影响.杉木纯林有机质含量和质量均低于混交林,且随栽植代数的增加有机质含量和质量呈下降趋势,林地土壤肥力下降.最后提出应加强对土壤有机质周转模型、有机质组分,尤其是活性有机质以及有机质与全球碳循环关系的研究.

Abstract: Soil organic matter(SOM) is an important component of soil and an important carbon pool of terrestrial ecosystems,which plays an important role in soil nutrient cycling and in the balance of global carbon cycle.This paper discussed the SOM quality in Chinese fir plantation,the influence of rotation on SOM content,the change of SOM during Chinese fir growth,and the effect of human activities such as burning,site preparations and fertilization on SOM.Human activities changed soil environment including soil moisture,temperature,total porosity and nutrient contents,and hence,made the turnover of SOM slower or quicker.The content and quality of SOM in mixed forests were higher than those in pure Chinese fir plantations,and decreased with rotation.In the last part of this paper,some issues to be further researched were put forward,including the turnover model of SOM,its components,and its relationship with global carbon cycle.

Key words: Chinese fir plantation, Soil organic matter, Continuous planting
