摘　　要：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。This paper takes the Naxiaohegou catchment as an example to introduce the main technology and methods of the GIS-based digital system for catchment.The design of the system adopts a three-level structure and is developed in the runtime environment of Microsoft Visual Studio and Java Server Pages.Based on the ArcGIS development platform,all kinds of data which are collected at different time are able to be fully incorporated into the system,and the research results can be clearly presented in it.Through the system,we can conclude that the establishment of the digital small-catchment system builds a solid foundation on researching on models of water-soil erosion forecasting and water-soil conservation management.
