For Gansu province that is famous for its draggling and aridity, it is very important to research the relation between water resources carrying capacity and the development of social economy in drainage areas roundly, and to harmonize the relation of living water demand, production water demand and zoology water demand,.

本本阐明全省分流域的水资源数量、质量，在不同时期的可利用水资源量、需水量、可供水量，提出合理的水资源配置方案，分析评价水资源的承载能力，并提出有关对策措施。

The excising quota system for distributing water resources has its innate defects and disadvantages. In order to minimize and finally to eliminate the imbalance between supply and demand of water resources, the thesis argues that it is necessary to establish water rights marketing in China, and to achieve the unity of justice and efficiency in administration ,therefore, we ought to bring new ideas to the administrative systems concerning water resources.

为提高水资源的利用效率，实现水资源的可持续利用，实现以流域为单位的整体性开发与保护，在水资源配置过程中引入市场机制，建立与完善水权市场己势在必行，这必然也对水权市场的管理提出更高的要求。

The natural runoff for 1983 to 2000 from Linjiacun and Huaxian gaging station, and industrial and domestic wastewater discharge for 1989 to 2006 in Anhui province is used. It is found that higher the degree of autocorrelation, higher the precision.

并分别对渭河流域的林家村站和华县站1983-2000年的年径流数据以及安徽省1989-2006年的工业和生活废水排放量数据进行了实例分析，发现自相关程度越高，精度越高。

SWAT model is a kind of distributed hydrologic model with the ability to evaluate the effects of landuse change on hydrologic response. This model was applied in Cao River catchment of Miyun reservoir basin. First, the sensitive parameters were identified through sensitive analysis. Then, the calibration and validation for flow and sediment were performed from 1986 to 1991 at Xiahui gaging station. The results of model evaluation show that the streamflow was simulated excellently, and sediment is also well simulated.

将可表征土地利用变化对水文响应影响的分布式水文模型SWAT应用于密云水库潮河子流域，对模型的敏感性进行了分析，并采用1986~1991年下会水文站数据对其径流量和泥沙负荷进行了率定和验证，模型评估结果表明该模型对径流的模拟效果非常好，对泥沙的模拟效果较好。
