摘要: 如何科学高效地提取大尺度流域水文特征参数，为水资源管理提供基础分析数据，是当前生产需要中急需解决的问题。本文基于DEM、采用“IDDEA”算法实现了汉江流域水系河网的自动提取，采用二叉树二元编码进行河网编码，构建了汉江流域河网水系的空间概化模型，提取了汉江流域内任意涉水工程点的流域水文特征参数信息，为流域水资源管理和技术决策提供支撑。
Abstract: How to extract the hydrological characteristic parameters of large-scale watersheds scientifically and efficiently to provide basic analysis data for water resources management is an urgent problem. Based on DEM data, the automatic extraction of the river network of the Hanjiang basin was realized using the “IDDEA” algorithm, a spatial generalization model of the river network as constructed using binary coding for river network coding, and the hydrological characteristics at any point in the basin can be extracted. The study could provide technical support for water resources management and decision-making.
