基于GIS的松花江水环境风险信息管理系统开发

摘要

This study develops a water environmental risk source information management system of Songhua River based on GIS technology ,according to its risk source status and the demand for risk source classification .The construction of risk source spatial database aims to realize the management and query of risk source in spatial data .At the same time ,the typical industry and sensitive target method is taken to identify the risk sources . According to the risk source classification model , the implementation of the classification of the risk source in Songhua River basin will be made to provide the data technology and management tools for the management of the administrative department of environmental protection .%根据松花江流域风险源现状，以及对风险源分类的需求，研发基于G IS的松花江水环境风险源信息管理系统。构建风险源空间数据库，实现对空间数据中风险源的管理和查询。同时采用基于典型行业和敏感目标方法对研究区域内风险源进行识别。根据风险源分类模型，实现松花江流域风险源的分类，可以为环境保护部门提供数据支持和管理工具。
