淮河上游流域土地利用变化对 次暴雨产沙影响研究
Research on the impacts of land use change on single storm sediment yield characteristics of the upper Huaihe Basin
摘要
Abstract
The change of land use alters not only hydrological cycle but also sediment yield process. The paper took the basin above Dapoling hydrological station in the upper reaches of Huaihe river as the study area. Based on data of land-use,and data of corresponding hydrology and meteorology in each 10 rain-storm in 1990s and 2000s, it modified the water - sediment model to simulate the sediment delivery process of Dapoling station with 0 . 5 hour as time scale and analyzed the impact of land use change on the relationship between rainfall and sediment load. Based on the parameters gotten in 1990s and 2000s,the paper simulated, sediment delivery process of 10 storms' so as to analyze the impact of land use change on sediment yield. The results indicated that the simulated results meet precision demand. The land use pat-tern changed the relationship between rainfall and sediment load. The change of land use from 1990s to 2000s mitigated the soil erosion of watershed, and resulted in the decrease of sediment load, peak and E-rosion modulus. The results can provide the scientific reference for the water and soil conservation of Hua-ihe basin, rich and innovate the theory and method of water and soil loss simulation in humid and semi-humid region.关键词
