以南小河沟数字小流域系统为例,介绍了基于GIS技术构建数字小流域系统的主要技术和方法。系统采用三层架构设计方法,在ArcGIS软件平台基础上,利用Visual Studio和JavaServer Pages进行二次开发,实现南小河沟数字小流域系统建设,将长期积累的各级各类数据进行充分整合和集成,将各类试验研究成果进行形象直观展示。数字小流域系统的建设,为进一步开展流域水土流失预测预报模型及水土保持综合治理效益分析评价模型研究奠定了坚实的基础。
Taking Xiaoxiagou digital small watershed system in south as an example, the main technologies and methods of constructing digital small watershed system based on GIS technology are introduced. Based on the ArcGIS software platform, this system uses Visual Studio and JavaServer Pages for secondary development to realize the construction of the system of digital small watershed in Nan Xiahe Gully and fully integrates and integrates all kinds of data accumulated at various levels for a long time. All kinds of experimental research results visual display. The construction of the digital small watershed system lays a solid foundation for further research on the prediction model of soil and water loss and the benefit analysis and evaluation model of soil and water conservation.
