坡面泥石流的发生是地貌信息的综合反映,是地表能量在各种因素影响下的再分配。坡面泥石流堆积物是坡地系统总能量减少的最好证明,堆积物体积的大小与坡面泥石流宽度、坡积物厚度、流域高差、流域狭长度、坡度和沟谷纵比降等地理要素密切相关。本文以北碚区坡面泥石流为例,初步探讨了坡地总能量的减少与各种地貌要素的关系,并通过多元回归的方法求取了坡地总能量减少的回归方程。检验后证明回归系数与0有显著差别,该回归方程有意义。
The occurrence of debris flow on the slope is a comprehensive reflection of geomorphological information and is the redistribution of surface energy under the influence of various factors. The debris flow debris on the slope is the best proof that the total energy of the slope system decreases. The size of the sediment is closely related to the geographical factors such as the width of the debris flow, the thickness of the slope sediment, the elevation of the catchment, the narrowness of the catchment, the slope and the vertical gradient of the valleys Related. Taking the slope debris flow in Beibei area as an example, this paper discusses the relationship between the reduction of total energy and various geomorphic factors in slopeland and obtains the regression equation of the total energy reduction of slope by multivariate regression. After the test proved that the regression coefficient and 0 are significantly different, the regression equation makes sense.
