In this study, to take Canjiang Basin as an example, technical framework TMYL plan is proposed, constructing the watershed management system for the goals to maintain the health of aquatic ecosystems and water quality objectives. In ARCGIS9.3 environment, a core-based control unit for the management, online monitoring of pollution sources as supporting the construction of three-tier monitoring system is established, in the use of GIS-overlay technology. With the establishment of performance evaluation and assessment analysis on water pollution prevention, this platform provides aid decision making for the total control of water pollution control programs and measures. Practice shows that, the statistical analysis of geographic information during the water pollution control process is an important tool, which provides an effective work platform and reliable technical support to achieve the business objectives of river water quality management for data management, spatial analysis of graphic expression and spatial decision. The management with the control unit as the core management is proved to be important means for water ecological health to achieve sustainable development of river basin, and for river water quality to meet long-term ecosystem services.%以赣江流域为例,提出了基于GIS的TMYL计划技术框架,构建了以保持水生态系统健康为目标的流域水质目标管理技术体系.在ARCGIS9.3的环境中,利用GIS的叠置技术,建立基于控制单元为管理核心、污染源在线监控为配套建设的三级监控体系.结合流域水污染防治绩效评估体系的建立及评估分析,为流域水污染控制的总量控制方案和对策措施提供辅助决策依据.实践表明,在水污染防治过程中,地理信息数据的统计分析是实现流域水质目标业务化管理的重要工具,为数据管理、空间图形表达和空间决策分析提供有效的工作平台和可靠的技术支持.以控制单元为管理核心的管理方式,是实现流域水生态健康可持续发展,流域水质长期满足水生态服务功能的重要手段.
