摘　　要：藉助MATLAB工具 ,对泥石流沟的六个地貌要素之沟床比降与切割度、流域面积与主沟长 ,用最小平方距离法进行了初步处理分析的探讨 :建立了线性相关的回归方程 ,并与用最小二乘法得到的线性回归方程进行比较 。On the base of MATLAB, the regression equation of the groove gradient and the degree of cutting is built by the method of least square distances. Then, this compare of results by the method of least square distances and by the method of least squares if my own work. The estimates is improved. Same works of the drainage area and the length of main groove are made. drawn.
