九龙江北溪流域河流特征及其构造指示意义
Geomorphological Features and Its Tectonic Implication of Beixi River Basin,Jiulongjiang Area,Fujian Province
摘要
Abstract
River concave degree index,steep index and sinuosity index extracted from DEM data by using bedrock channel erosion mode are used for reveal the geologic structure activity characteristics in Beixi river basin,Jiulongjiang area.Through the analysis of geomorphic parameters,there is the law of diminishing from northwest to southeast.Rule out Climate factors and back rock factors,we consider that the distribution of river steep index reveals the regularity of uplift rate change（diminishing from northwest to south east） of Beixi river basin,Jiulongjiang area,which is similar to the result of crust movement rate from using method of precision level material calculating vertical.关键词
