| 摘 要： | 依据贵州后寨河流域15个水化学监测站1981~2001年的水化学监测数据,对该流域水化学特征及其与流域降雨量、岩性及土地利用的关系进行了统计分析。结果表明,后寨河流域水化学组成呈明显的时间和空间分布特征。主要离子的变化与降水丰、枯季节、丰枯周期年变化有紧密的关系;其变化趋势在空间上呈有规律的分布,基本反映了水体中离子的空间变化特征。

| Abstract: | Based on the data of 15 hydro-chemical monitoring stations in Houzhai River Basin from 1981 to 2001,the hydro-chemical characteristics and the relations between hydro-chemical characteristics and rainfall,lithology,and land use were analyzed.The results indicate that the hydro-chemical constitutes show obvious spatial-temporal distribution characteristics.The variations of main ions are closely related to precipitation in flood season,dry season,and precipitation in different years.The main ions vary regularly in space,which presents the spatial variations of the ions on the whole. |
