为提高无资料地区临界雨量分析结果的精确度，采用双曲正切产流模型和单位线流域汇流模型，结合山西省清凉寺沟流域水文下垫面产汇流模型参数，对实测暴雨洪水进行了模拟分析。结果表明：径流深及洪峰流量的合格率均为75％，参数是合理、可靠的，据此得出了该流域不同流量级时的临界雨量。
為提高無資料地區臨界雨量分析結果的精確度，採用雙麯正切產流模型和單位線流域彙流模型，結閤山西省清涼寺溝流域水文下墊麵產彙流模型參數，對實測暴雨洪水進行瞭模擬分析。結果錶明：徑流深及洪峰流量的閤格率均為75％，參數是閤理、可靠的，據此得齣瞭該流域不同流量級時的臨界雨量。

In order to improve the region without data of critical rainfall of the accuracy of analytical results,using the hyperbolic tangent runoff model and unit hydrograph of watershed concentration model and combing with the parameters of hydrological underlying surface runoff model of Qingliangsigou watershed in Shanxi Province,the observed storm flood was simulated and analyzed. The results show that the depths of runoff and peak flow of qualified rate are all 75%,the parameter is reasonable and reliable. Based on that,the critical rainfall of different flow levels of the basin has been obtained.
