典型边坡对土壤酶活性的影响
Impacts of Slope Types on Soil Enzyme Activities
摘要
Abstract
This study is to investigate the activities of soil invertase and urease and their seasonal variation in different slopes in eastern Chengdu Plain.The results show that,in the natural slope and railway slope,the enzymes are the most active in spring and autumn and in the tillage slope,however,their highest activities occur in spring while the lowest in autumn.The activities of invertase and urease were in the order of natural sloperailway slopetillage slope;and no regular seasonal variation occurs with different landuse types.We conclude that slope types have significant effect on activities of soil invertase and urease（P0.05）.关键词
