土地利用变化对东江流域径流量的影响
Impact of land use change on the runoff in Dongjiang basin
摘要
Abstract
An improved monthly SCS model was calibrated and used to simulate the runoff of each sub-basin of Dongjiang under different land use scenarios, based on the status quo of the land figures for two periods (the years 1980 and 2000) and the inputs of monthly hydrological data in the sub-basins Shuntian, Lantang, Jiuzhou and Yuecheng. Simulations of the four sub-basins by this model are satisfactory. The results show that since 1980s the land use in the Dongjiang basin have been characterized with a prominent increase in built-up land and strong farmland, while little change in forest, water and unutilized land. Land use change in the subbasins have caused increases in monthly mean runoff, maximum runoff and runoff in the flood period to different extent.关键词
