摘要

利用人工模拟降雨装置对影响坡耕地土壤入渗的诸因素进行了研究。发现坡面产流历时与土壤容重、初始含水率、坡度、降雨强度、耕作管理措施呈负相关土壤稳渗速率与降雨强度、耕作管理措施呈正相关

与土壤容重、初始含水率、坡度呈负相关。通过综合因素分析可知

影响坡面土壤入渗和产流历时的主要因子为土壤物理性质和耕作管理措施。

Abstract

Using the simulated rainfall methods

the affecting factors of soil infiltration are studied.The results show runoff time has a negative relationship with soil bulk

a ntecedent soil moisture

slope gradient

rainfall intensity

and different tillage measures;soil steady infiltration rates have a positive relationship with rainfall intensity and tillage measures

and have a negative relationship with soil bulk

antecedent soil moisture

and slope gradient.The major factors which affect soil steady infiltration rates and runoff time are soil physical property and tillage measures according to result of synthetic analysis.
