| 摘 要： | 根据水力侵蚀面蚀和沟蚀两种不同侵蚀形态发生过程尺度空间大小不一的侵蚀特点,确定了研究区面蚀和沟蚀的不同调查评价方法.面蚀的发生过程空间尺度小,选用小区调查方法进行,而沟蚀的发生过程尺度空间大,在典型调查小流域尺度进行全面调查.然后在两种尺度下,分析形成沟蚀和面蚀的影响因素,进行沟蚀程度和面蚀强度分级,并把研究成果展延到澜沧江凤庆河流域和晓街河流域.最后,以在典型调查小流域的研究结果为对照判别依据,判断风庆河和晓街河流域的土壤侵蚀状况.结果显示,澜沧江典型流域的面蚀强度差异不大,沟蚀是造成不同流域土壤侵蚀和沟道输沙差异的主要水力侵蚀形式.

| Abstract: | Both gully erosion and surface erosion were investigated. Since the scale of these different erosion processes is different, different methods are also needed for gully erosion and surface erosion. For surface erosion, plot observations were made, but for gully erosion a survey was conducted in the 4 sub-catchments. In both cases, the factors influencing soil erosion were analysed and surface erosion susceptibility and gully erosion severity were classified. Finally the soil erosion situation in the 2 face erosion study and the gully erosion survey. The catchments was assessed using the results from both the surclear difference in erosion between the different catchments is caused by differences in gully erosion, since surface erosion is quite similar in different catchments. |
