摘　　要：福建省是遭受崩岗侵蚀灾害最为严重的省份之一。本文基于野外详细调查,选取研究区2015年5月19日~7月20日8场降雨资料,采用灰色关联度法分析安溪县崩岗的降雨持续时间、降雨量、植被覆盖率和孔隙度4个影响因子的权重。结果表明：影响因子的优劣排序为：降雨量〉植被覆盖率〉孔隙度〉降雨持续时间。该研究成果为崩岗侵蚀机制与防治提供理论基础。Fujian province is one of the most serious areas that suffered from Slump Gully Erosion disaster. Based on detailed field investigation,and select 8 parts rainfall data as the sample from May 19 to July 20 in the study area,the gray correlation degree method was adopted to analyze the function degree of each factor that may induce rainfall duration,rainfall,vegetation coverage and porosity. The result shows： the order of factor is rainfall,vegetation coverage,porosity,and rainfall duration. The research results provide a basis theoretical about the Slump Gully erosion prevention Mechanism.
