摘要: 基于国产HIMS(Hydro-Informatic Modeling System)模型,以青海湟水流域为研究区域,利用1986-2000年33个雨量站和8个气象站的逐日降水和气温数据,对其径流变化进行模拟;选取流域内6个水文站同期的实测径流数据,进行参数率定及验证。结果表明:HIMS模型日、月率定及验证结果良好,在湟水流域具有良好的适用性。在此基础之上,分析了湟水流域1961-2010年降水及气温的变化趋势,并对不同气候变化情景下的水文响应(径流量)进行模拟分析。结果显示气候变化对湟水流域径流量变化趋势影响显著,随气温升高和降水量的减少,径流量呈明显的减少趋势,反之,呈增加趋势。

Abstract: It is important for rational water use and water management to study the change of runoff processes in response to climate change. Based on HIMS(Hydro-Informatic Modeling System) model, using daily precipitation data from 33 rainfall stations from 1986 to 2000, and daily maximum and minimum temperature measured at 8 meteorological stations, this paper presents a simulation of runoff processes in the Huangshui river basin in Qinghai province. Parameter sensitivity analysis and validation of the simulation are conducted using the recorded runoff data from six hydrological stations during the same time period. Results indicate that efficiency coefficient and correlation coefficient of the simulated daily data at five stations exceed 0.5, except Shiyazhuang station; the efficiency coefficient and correlation coefficient of the simulated monthly data at five stations exceed 0.9. Daily and monthly sensitivity analysis and validation generates good outcome as well, demonstrating that the HIMS model applies to the runoff processes in the Huangshui River basin very well, and can be used to simulate the scenarios of areal responses to climate change, which meets the requirements of water resources management. Based on this, the changes of precipitation and temperature in recent 50 years(from 1961 to 2010) in the Huangshui River basin are analyzed, and the hydrological responses(runoff) to 9 types of possible climate change scenarios are simulated and analyzed. The results suggest that climate change has significantly effects on the runoff of the Huangshui River basin. If temperature rises and precipitation decreases, then runoff shows a strong tendency to decrease; on the contrary, if changes of temperature and precipitation reverse, runoff shows a tendency to increase. In addition, in the Huangshui river basin, precipitation is the key climatic factor, and the effect of precipitation change on runoff processes is significantly greater than that of temperature change.
