大凌河流域水土保持信息系统的建立与应用

Development and Application of Soil and Water Conservation Information System (SWCIS) for Daling River Watershed(DLRW)

将 GIS(地理信息系统 )、RS(遥感技术 )、Fox Pro数据库等技术集成 ,应用于“朝阳市国家重点治理区大凌河流域治理工程”建设实践 ,建立了“国家重点治理区大凌河流域水土保持信息系统”。该系统包括 :1属性数据信息管理子系统 ;2图件空间信息管理子系统 ;3流域规划设计与措施配置子系统 ;4效益监测、评价与预测子系统。使用该信息系统对区域的 81条小流域进行了规划设计、治理开发措施的优化调控和效益的分析评价 ,实现了大凌河流域治理工程管理决策的科学化 ,促进了大凌河流域治理工程的高质量完成 ,达到了工程的高效率管理和工程的高收益 。

Applying the integrating technology of geographic information system(GIS) and remote sense system(RS) and SQL database system (FoxPro) to the constructing practice of the Daling river watershed harnessing project; the SWCIS for the DLRW was developed in the mainly harnessing area of China. It is consisted of four sub systems: ①The sub system of attribute data management for basic condition of the DLRW; ②The sub system of spatial data management for the graph and photograph of the DLRW; ③The sub system of the harnessing measure plan, design and control of the DLRW; ④The sub system of the benefit monitor, evaluation and prediction of the DLRW. By the SWCIS, we can design and work out the plans of 81 small watersheds of the DLRW, and optimum design plans, and control the harnessing measures. Meanwhile, we can evaluate and analyse the benefits of the DLRW. This study of the SWCIS is not only advantageous to the completion of the Daling river watershed harnessing project, but also to the ecological environment protection and soil and water conservation, then to the sustainable development and utilization of soil and water resources in China.
