摘 要: 结合基于遥感数据获得的土地利用结果与SCS模型,在GIS环境下模拟了上海浦东新区不同阶段的土地利用/覆被变化对地表径流的影响。结果表明:土地利用结构与格局的变化使地表径流深度趋于增大;同时,在浦东新区城市化的不同时期,由土地利用/覆被变化引起的地表平均径流深度变化也不相同。 Through integrating remote sensing data and SCS model under the GIS environment, the impact of land use and land cover changes on the surface runoff in Shanghai Pudong New District is studied. The result shows that the land use structure and pattern change result in the increase of surface runoff depth. Moreover, the changes of average surface runoff depth induce by land use and land cover changes are different in the different stages of Pudong New District urbanization.
