摘　　要：在皂河无实测流量资料的情况下,为了分析其径流特性,首先应用径流系数法由降雨资料推求流域径流量,进而对求得的径流序列趋势、周期、持续及突变等特性加以分析。结果表明:年径流序列变化表现为不显著的下降趋势;存在3 a、6 a和17 a的准周期;具有Hurst效应;年径流序列在1976,1985年和2006年发生了突变。There was no measured data of runoff volume in Zaohe River Basin of Xi＇an City,in this circumstance,the method of runoff coefficient was used to calculate the runoff volume,and analyzed the characteristic of its tendency,periodicity,persistence and mutation.The results shows that the annual runoff showed an indistinctive declining trend,and it exist the quasi-periodic signal of 3a、6a and 17a,it had obvious Hurst phenomena,and the mutation points appeared in 1976,1985 and 2006.
