摘　　要：利用ArcGIS 9.2和ArcView 3.2对玛纳斯河流域进行图幅拼接、配准、数字化、生成DEM,在水文分析基础上完成了水系提取及分级。提取结果与石河子南部山区水系实际分布基本吻合,呈现树形分布特征并与地形地貌特征吻合,符合水文学规律。ArcGIS 9.2 and ArcView 3.2 were used to carry on map sheet splicing, map registering, map digitization on Manasi river basin to produce DEM, the river system extraction and grading were achieved based on hydrology analysis. The extraction results basically tallied with the actual distribution of the river system in the southern mountainous of Shihezi, the distribution of the river system presented the shape of tree distribution characteristics and tallied with the terrain and landform characteristics, conformed to the hydrologic law.
