摘要
基于遥感(RS)和地理信息系统(GIS)的分布式水文模型已成为当前水文科学发展的前沿,地理信息建模系统是目前地理信息系统研究的热点问题之一。目前实现通用GIS空间分析功能与水文模型的集成主要有四种途径:水文模型嵌入GIS平台,GIS功能嵌入水文模型,水文模型和GIS的松散连接以及水文模型和GIS的紧密连接。本文提出的ArcTOP分布式水文模型系统,运用ArcViewGIS提供的宏语言,将以物理概念为基础的分布式水文模型TOPKAPI和GIS紧密连接,实现分布式水文模型和CIS的完全集成。
Distributed hydrological models based on Remote Sensing (RS) and Geographical Information Systems (GIS) have become disciplinary frontiers of hydrological research, while developing GIS-based modeling systems are becoming more of an issue in GIS applied research. At present, the integration of hydrological models and GIS usually takes four approaches: hydrological modules embedded in a GIS, GIS functions embedded in a hydrological model, loose coupling of hydrological models and GIS and tight coupling of hydrological models and GIS. This paper introduces a distributed hydrological modeling system, namely, ArcTOP - a realization of full integration of a hydrological model within a GIS environment, which tightly couples a cell-based distributed model TOPKAPI with the ArcView GIS by using the macro language Avenue of ArcView.
