东江流域河水电导率形成机制
Mechanism of River Electrical Conductivity in the Dongjiang River Basin
摘要
Abstract
Based on the hydrochemical data of water samples from the Dongjiang River Basin in dry and wet seasons, the mechanism of river electrical conductivity ( EC ) is considered. The results show that EC in the Dongjiang River Basin is 85. 3μS/cm in January and 87. 7μS/cm in July. The share of weathering conductivity ( Cw ) , seasalt conductivity ( Cs) and anthropogenic conductivity ( Ch ) is 46. 4% , 19. 6% and 33. 9% respectively. It indicates that chemical weathering is the main contributing factor for EC in the Dongjiang River Basin. The humanity interference cannot be neglected, while the seasalt settlement has certain effects on the hydrochemistry. Furthermore, the nonparametric statistics methods and spatial analysis are used to prove that the geographic features (lithology, landform, soil, vegetation and human activities) have played an important role in the EC mechanism.关键词
