摘　　要：全球气候的暖干变化,将会加剧水资源供需矛盾。在分析渭河流域降水及径流量时空分布基础上,根据渭河产流和水平衡原理,依据假定的未来不同气候变化情景,采用模型模拟方法,分析了渭河流域地表水资源量对气候变化的响应趋势。提出了该地区水资源合理利用方案。The global warming has intensified the contradiction between the water supply and demand. Based on the analysis of the characteristics of the precipitation and runoff in the watershed of Weihe river, an evaluation model was established which is used to simulate the surface flow and ground water runoff with the consideration of the runoff yielding and water balance. According to the different kinds of climate scenarios, the responses and variation of the water resources to climate change were analyzed. Based on the actual social, environment and economic development of this region, a reasonable proposal for water resources use is given.
