摘　　要：研究湖北省不同级别山区河流的形态特征和产流特性,可为水利工作中相关参数取值提供借鉴。利用湖北省第一次全国水利普查成果,对省内934条山区河流的河长、流域面积分别进行统计分析。结果表明:湖北省各级山区河流的河长和面积不服从正态分布;河长和流域面积表现出不同的规律特征,且具有较好相关性,但淮河和唐白河的河长-面积与其他样本差异显著。不同级别河流的径流系数分布呈现不同统计特征,流域尺度较大的河流,其径流系数分布相对比较集中,随着流域尺度的减小,径流系数越分散,2~5级河流径流系数在均值两侧出现两个分布集中区。Studying the morphological characteristics and runoff generation characteristics of rivers in different grades of mountainous areas in Hubei Province can provide reference for the determination of parameter in water conservancy work.Based on the first national survey of water resources in Hubei Province,this paper analyzed the river length and drainage area of 934 mountain rivers in Hubei Province.The results showed that the statistical characteristics of river length and area of mountain rivers at all levels in Hubei Province do not obey normal distribution;the river length and basin area presented different characteristics.There was a good correlation between the length and area of rivers at all levels in Hubei Province except Huaihe River and Tangbai River,which were significantly different from other rivers.The distribution of runoff coefficient of rivers of different levels presented different statistical characteristics.The distribution of runoff coefficient of rivers with large basin scale was relatively centralized.With the decrease of basin scale,the runoff coefficient was more dispersed,and there were two distribution concentration areas on both sides of the mean value of the runoff coefficient of rivers of level 2 to 5.
