摘要
高寒区产汇流规律复杂,且水文实测资料稀缺,给流域径流分析带来诸多挑战。以宗通卡坝址以上流域为研究对象,采用传统的水文比拟法,依据干流上下游水文站资料,推求坝址1960~2009年月径流系列。同时基于全球气象数据产品,考虑融雪径流的影响,构建了适用于该流域的HBV半分布式水文模型,模拟坝址1960~2009年月径流系列。通过对比两种方法的径流成果,分析其异同,认为HBV模型可用于高寒区径流模拟。
The runoff yield and concentration characteristics are complex in alpine area.Moreover,the hydrological data are scarce,which brings many challenges to watershed runoff analysis.In this paper,the basin above the Zongtongka dam site,Tibet alpine area,is selected as the study area.Based on the runoff data of upstream and downstream on the trunk stream,the traditional hydrological analogy method is adopted for determining the annual and monthly runoff at the dam site from1960to2009.Meanwhile,based on the global meteorological products,the semi-distributed HBV model is constructed for the basin by considering the effect of snowmelt runoff.Then,the monthly runoff at the dam site from1960to2009is simulated.Through comparing the runoff results of the two methods,the differences between them are analyzed and the results show that the HBV model can be used to simulate runoff in alpine regions.
