英文摘要：

Pond re-storage times refers to the ratio of effective utilization of water and pond capacity, and is one of the important characteristic values reflecting the water supply capacity of a pond. It is the important parameters indicating water supply estimates and capacity determination of a pond. It has great guiding significance for regional pond planning and regulation of water resources in irrigation. At present, domestic and foreign scholars have carried out considerable research work on rainwater utilization, but fewer relevant outcomes have been projected on pond re-storage times in a hilly region. A pond in a hilly region has the features that small-scale projects monomer pond, a small amount of water, its water storage capacity is small, and its controlled irrigation area is small, but the distribution is wide, with a large number of groups, groups of large capacity, and so on. For this type of small water storage facilities, generally not hydrology and runoff observation points, there are almost no measured hydrological and runoff observations, and this has caused great difficulties for hydrological calculations. Predictions in ungauged basins （PUB） has been the focus of hydrology research and one of the difficult problems, and has been a widespread concern of scholars at home and abroad. A SCS model was the design flood of a small watershed model that was presented by United States Department of agriculture soil conservation service in the 1950s. It has the features that make the calculation process simple, with fewer required parameters of data readily available, especially for areas without data or lack of data. That has been widely used in various hydrologic problems, such as river engineering planning, soil and water conservation, flood control, city hydrology, and in ungaged basins, and achieved good results. On this basis, the pond irrigation area of Jianghuai Hilly as an example was selected, with hydrological simulation without any data of the pond irrigation district was resolved by the SCS m
