摘要
在分析河流水环境系统特征的基础上 ,探讨了GIS网络分析技术在河流水污染追踪中的应用方法。主要内容包括数字化河系网络模型的建立、河流水环境数据库的建立与集成、河流水污染追踪应用的方法与步骤 ,并以汉江流域河系为例 。
River is an important water source for human living and production Management of its water quality and pollution sources is one of the major tasks of river basin management of water environment All rivers in a river basin form a river network Some kinds of GIS software provide a module specially for solving network related issues Based on an analysis of the features of river water environmental system, this paper studies the method of application of GIS network analysis technology to river water pollution tracing,which include establishment of digital river network model and river water environmental database, integration of associated with river water environmental data, and implementation of river water pollution tracing In addition, a prototype study has been carried out in the Hanjiang River basin
