%X 泥石流现象多发生在条件具备的山区, 暴发突然, 发生的准确时间很难预知, 因此将中心点三角白化权函数法 运用于硬梁包水电站左岸磨子沟泥石流易发性评价中。将所在地的观测指标划分为若干个可定义的类别, 从而对 泥石流易发性进行评估, 得出评估结果为轻度易发, 并将其与基于端点三角白化权函数的评估结果和实际情况进行 比较, 两者评价结果一致, 而前者的评估过程更加科学合理并且与当地实际完全相符, 从而在此评价基础上采取建 设性措施对该地泥石流沟进行了排导和防护。  Debris flow o ften occurs in the mountain area w ith r ipe conditio ns, and its sudden outbreak makes it difficult to pr edict the ex act occur rence time. In this paper , the tr iang le w hitening w eight function method of cent ral point w as applied to evaluat e the pro ne degr ee o f the debr is flow o n the left bank o f gr ind g ully of the Ying liang bao hydro pow er station. The observ at ion in2 dexes w ere div ided into sev er al def ined categ or ies, w hich can assess the susceptibility of debr is flow using the t riang le whitening weig ht function metho d of centr al point. The evaluation results show ed that pr one degr ee o f debr is f low is mild in the study a re2 a. Compa red w ith the results o bt ained fr om the triang le whitening w eight functio n of endpo int, the tr iang le whitening w eig ht function method of central po int met ho d is mor e scientific and reasonable and fully co nsistent with the act ual co nditions. On the basis, the constr uctiv e measures w ere pro posed for the drainag e and pro tection of the debr is flow g ully in the study ar ea.
