摘要: 通过对地带性常绿阔叶林、杉木人工林、农田、竹林等不同土地利用方式下土壤有机质总量、活性有机质及其组分的研究,发现土地利用方式对土壤有机质和活性有机质各组分的影响差异显著,其中阔叶林含量最高,杉木人工林低于阔叶林,竹林和农田最低。这些差别主要是由于凋落物的数量、质量以及各种管理措施不同所致.

Abstract: To investigate the influence of land use on soil organic matter,experiments were conducted in nature evergreen broad-leaved forest,Chinese fir plantation,farmland and Phyllostachys.pubescens stand.The results indicated that total soil organic matter and fractions of active soil organic matter were significantly influenced by land use.The content of total soil organic matter and active soil organic matter differed significantly,among which broad-leaved forest was the highest,and P.pubescens stand was the lowest.This difference was mainly resulted from the difference of the quality and quantity of litter and management practices.
