Design and realization of GIS model for hydrological cycle of a small watershed on the loess plateau

摘要

摘要: 探讨了小流域水循环地理信息系统(GIS)的研究和构建：其中包括GIS在水文水资源系统中的应用模式，小流域水循环地理信息系统的系统设计的原则，系统架构设计和系统功能设计。应用组件式技术，采用新一代组件式GIS开发平台ArcObjects与可视化开发语言VB，以黄土高原六道沟小流域为例，设计建立小流域水循环空间数据库和属性数据库，并在此基础上，建立了小流域水循环地理信息系统。系统能够采集、表达和输出小流域水循环过程各类数据，系统还提供实现水文模型与系统的集成接口，为黄土高原小流域水循环过程研究提供数据采集、表达和分析支持。

Abstract: In this paper, a GIS for hydrological cycle of small watershed was designed and realized. This was done by three steps. First, combination modes of GIS and hydrological models were developed. Then, design of framework, functions and database of the system was discussed particularly. Finally, the GIS model for hydrological cycle of small watershed was realized with VB and ArcObjects for the Liudaogou small watershed on the Loess Plateau as a case study. This GIS includes input，management, and output of spatial data and attritute data of hydrological cycle of the small watershed, furthermore the model combines hydrological models with GIS technology, so this GIS is useful for the research of hydrological cycle of a small watershed on the Loess Plateau.
