摘    要:为确定规划中无径流资料的云首水库工程规模,需要分析计算设计年径流量及年内分配.采用地理综合法计算了云首水库坝址以上控制流域年径流的均值、变差系数和偏态系数,获得了该流域在丰水年(P=20%)、平水年(P=50%)、枯水年(P=75%)和特枯水年(P=95%)的设计年径流量分别为2 393,1 198,654,318万m3.采用水文比拟法确定了年内分配.研究表明,采用地理综合法计算年径流的均值、变差系数和偏态系数,采用水文比拟法确定年内分配,可作为无资料地区年径流合理分析计算的方法组合.

关 键 词:设计年径流量  径流年内分配  地理综合法  水文比拟法

Abstract:In order to determine the size of the planned Yunshou Reservoir without runoff data,it's necessary to calculate and analyze design annual runoff and runoff annual distribution. The geography comprehensive method is adopted to compute the mean,variation coefficient and skewness coefficient of annual runoff of the control basin above the dam site of Yunshou Reservoir. The runoff annual distribution is determined by hydrological analogy method. The results show that the design annual runoff under the frequency of wet year(P = 20%),normal year(P = 50%),dry year( P = 75%) and super dry year( P = 95%) is 23. 93 × 106m3,11.98 ×106m3,6. 54 × 106m3,3.18 ×106m3,respectively. Therefore,it can be a combination of methods to carry out a rational analysis of annual runoff in no data region that geography comprehensive method is used to calculate the average annual runoff,coefficient of variation and coefficient of skewness and hydrologic analogy method is used to calculate intra-annual runoff distribution.
Keywords:design annual runoff  runoff annual distribution  geography comprehensive method  hydrological analogy method
