Afterthe travel time of each cell being calculated,the frequency distribution of the times of arrival of individual water droplets at the catchment outlet -GIUH,is obtained.
流域中每一个网格单元的汇流时间得到后，将其看作随机变量，进行统计分析后，得到汇流时间的频率分布—GIUH。

Haloxylon ammodendron population congregated within the scales of 4m×4m、8m×8m、16m×16m and Haloxylon persicum population congregated in 1m×1m、8m×8m scales.
与此同时,分析结果还表明,用频次分布型检验法判断种群空间格局的类型受样方尺度大小的限制。
