摘要:

根据汉江中下游农业面源污染治理决策的需求,应用遥感与GIS一体化的方法,研究设计了汉江中下游农业面源污染动态监测信息系统的结构、功能及数据库的组成,并建立了可运行的汉江中下游农业面源污染动态监测信息系统,在系统支持下可有效地实现汉江中下游农业面源污染动态监测、最佳管理措施的选择以及区域农业面源污染综合治理规划.系统可以为地方政府相关部门决策提供依据,对有效的保护汉江流域水资源环境,控制汉江流域水污染有着重要意义.

The Establishment and Application of Agricultural Non-point Source Pollution Information System in Hanjiang River Watershed
Abstract:

After analyses to spatial planning decision making requirements of agricultural non point source (AGNPS) pollution in the region of Hanjiang River watershed, we designed the structure, function and database of agricultural non point source pollution information system using the methods of integrating GIS integrated and remote sensing. At the end, the information system was developed. The system comprises of three subsystems: the spatial analysis and remotely sensed data processing system, the model management system and the statistics database management system. This system has multifunction with detailed spatial and attribute database including fundamental geographic elements, eco environment, landform, remotely sensed image and statistics data. Agricultural non point source pollution was then detected dynamically. Our integrated system provides a robust and user friendly environment for the standard three step management procedure of non point source pollution:(1)critical area identification. (2) Best Management Practices (BMPs) selection, and (3) comprehensive regional pollution control plan. It will be helpful for local government to make a feasible decision on this issu.
