甘肃渭河流域土地利用及覆被变化对径流的影响研究
Study on impact from change of land-use and land-cover on runoff in Weihe River Basin in Gansu Province
摘要
Abstract
Based on the remote sensing image and landsat TM image data of 1980 and 2000, the spatial distribution and transfer of the land-use and the land-cover change in Weihe River Basin are analyzed with the classified statistic method and sectional proportion percentage index method. Taking Qingyuanhe River Catchment as a study case, it is simulated by a classified hydrologic model. The result shows that the change of land-use and land-cover within the area of the Loess Plateau has a significant impact on the annual basin runoffs therein; I. E. the impact on runoff represents an obvious seasonal feature, while the impact on the flood process created by rainstorm has a delay effect as well.关键词
