【摘要】 无资料或资料稀缺地区的水文模拟研究，是近代国际水文水资源研究的热点和难点问题之一。本文针对中国西北内陆资料稀缺地区的特点，采用星载雷达TRMM PR(Tropical Rainfall Measuring Mission Precipitation Radar)资料与实测站点资料相结合的方法插值计算资料稀缺流域的降水空间分布，并在新疆开都河流域构建了大尺度分布式陆面VIC(Variable Infiltration Capacity)水文模型，进行了水文模拟计算。试图在中国西北资料稀缺地区的水文模拟方法上做一些应用性的探讨。 本文在前人研究基础上，总结了中国西北部干旱半干旱地区的水文特性，降水及径流的时空分布规律。通过分析星载雷达TRMM PR资料的空间相关关系，提出了利用TRMM星载雷达资料和少量站点实测资料推算无资料地区的降水空间插值方法，并对干旱半干旱区的新疆开都河流域降水和气温资料进行插值，应用了大尺度分布式VIC水文模型，对开都河流域大山口站1981～1987年月径流量过程模拟并进行了验证。结果表明，本文提出的开都河流域降水插值方法是可行的，VIC模型在开都河流域的月过程模拟结果是准确的，能初步满足区域水资源分析的精度要求。 将大尺度分布式VIC水文模型开都河流域应用的水文参数移用到博斯腾湖流域，基于模型在博斯腾湖流域的水文模拟，初步分析了博斯腾湖流域1980～2001年的降水、蒸发、气温和入湖径流量等水文要素的变化，揭示了20世纪80年代以来博斯腾湖流域的水文特征及其变化趋势，为该地区的水资源开发利用提供参考。更多还原

【Abstract】 Hydrologic simulations in non-data or data scarce regions are now one of the hotspots and the difficulties in Hydrologic researches. In the view of the characters of data scarce regions in the northwest of China, this paper combines TRMM PR (Tropical Rainfall Measuring Mission Precipitation Radar) data and few observations to interpolate precipitation in data scarce areas. Macro-scale land hydrologic VIC (Variable Infiltration Capacity) model is established to testify it. It does some appliance research in hydrological simulation in data scarce region in the northwest of China.This paper summarized hydrological characters, distribution of precipitation and runoff in arid and semiarid regions in the northwest of China on the basis of the previous researches. It introduces a spatial interpolation method of precipitation according to the relationship of TRMM PR data and few observations in data scarce area. It interpolates precipitation and temperature of Kaidu river basin as an example, and macro-scale land hydrologic VIC model is established to simulate and validate the monthly runoff. The results show that this method is feasible in interpolation precipitation of Kaidu river basin. The simulation of VIC model in Kaidu river basin is accurate. It is able to use in area water resource to estimate and analysis of data scarce regions.Precipitation, evaporation, air temperature and runoff in Bositenghu Lake basin are primary analyzed on the basis of hydrological simulation of VIC model. It shows the hydrological features and trend of Bositenghu Lake basin from 1980s. It provides the reference for exploitation and utilization of local water resources.更多还原
