摘要
本文以澧水水系河流水文站实测的悬移质模数(1958—1983年)和离子径流模数(1958—1983年)作为依据,应用自然地理学的理论方法,剖析澧水集水区域物质侵蚀和淋溶强度。同时运用河流多年输沙量及离子径流量资料,分析了侵蚀物质的迁移规模及其时空变化规律。
In accordance with the moduluses of suspended load and ion runof measured during the years from 1958 to 1983 at the hydrological stations of the rivers in the Lishui river system,the eroding and leaching intensity in the Lishui watershed is dissected using the theory and the methods of natural geography.Meanwhile,with the data of sediment load and ion run- off of years,it is made to analyse the migrating exention and developing law in time and space of the eroded materials
