摘　　要：通过多次野外调查,发现安县长坡沟泥石流的发生主要受该区域地形地貌、地质背景、物源条件和降雨条件影响。分析该泥石流运动的特征值,提出修筑拦砂坝、疏导水流和回填裂缝的防治措施。Several field surveys show that the mudslides occurred mainly under the influ- ence of the area＇s topography, geological background, material conditions and rainfalls. An analysis is made on the eigenvalues of their movement. Control measures like building dams, diverting water and filling cracks are proposed.
