The probability grading for quantitative characters 400 large-flowered cultivars were chosed and their eighteen chief quantitative characters were tested and recorded according to the test method of morphological characters in the .The empirical distributions were determined by nonparametric test after the distribution range,mean value and variation coefficients of these characters were calculated and frequency diagrams were drawn.

数量性状分级选择代表性强的400个大菊品种，参照《菊花DUS测试指南》的形态性状测试方法，检测其18个主要的数量性状，并对性状的分布范围、平均值、变异系数进行统计计算，在此基础上，绘制了分布频次图，结合非参数检验判断性状的分布类型。

From the probabilistic equation of debris-flow occurrence, the curves of probability-slope-water level were obtained. One can see the influences of water level and sediment-layer slope on the probability of occurrence from the curves. The influence of coefficients of variation on occurrence probability are also shown in this paper.
