摘要 在TOPMODEL模型中地形指数的计算方法基础上,针对一些地形指数的改进算法指出了其中的不妥之处,认为之所以会出现这种改进算法是因为对于"径流在任一位置上的累积趋势"理解有所偏差所致,据此对该点提出了自己的理解和建议;针对坡度为0的栅格地形指数的计算提出了解决方法,所得结论愿与读者共飨。 On the basis of calculation method for the topographic index in TOPMODEL,the inadequacies are pointed out in view of improved ＇algorithms of some topographic indexes, and these improved algorithms are caused by misunderstanding of ＂runoff cumulative trend at any po- sition＂. Based on this point, understanding and suggestions are raised. Meanwhile, the method is presented for calculation of the grid topo- graphic index with slope of 0 raster.
