基于3S技术的大凌河流域水土保持管理信息系统建设

 为提高大凌河流域水土流失综合防治技术水平,在水土保持信息资料收集与抽样实地调查的基础上,应用RS、GPS与GIS技术,构建大凌河流域水土保持管理信息系统。该系统不仅利用了RS技术信息丰富、宏观性强等特性,还充分发挥了GIS具有的强大空间分析和管理功能。通过高效科学的管理决策过程,为水土保持监测工作的开展奠定了扎实的数据信息基础和更新方法基础,实现全流域水土保持信息资源共享及动态更新、动态管理和动态监督,从而使辽西大凌河流域水土保持管理实现了信息化、自动化、智能化和高效化。

Management information system of soil and water conservation in Dalinghe River Basin based on 3S technologies

In order to enhancing synthesis control of soil erosion in Dalinghe River Basin, based on collected information and materials of soil and water conservation and sampled investigating the plots, the management information system of soil and water conservation by the combining ways of RS, GPS and GIS technologies was established. And it not only utilized the abundant information of RS but also made full use of spatial analysis and management function of GIS was established. The fundamentals of management and decision-making system was well established by efficient and scientific approach, which also implements share, dynamic update, dymanic management and dynamic monitory of information in the basin. It realized the informational, automatic, intellective, and effective management of soil and water conservation of Dalinghe River watershed.
