环境模型与地理信息系统的耦合

通过对环境模型与GIS的特点进行分析,探讨了环境模型与GIS耦合以及GIS应用于环境模型的优势与方法,研究了环境模型与地理信息系统耦合的3种方法。分析了3种方法的特点,指出各种方法的优势以及不足,提出了环境因素影响下GIS空间分析的系统框架与实现方法,分析阐述了各个功能模块。以雾影响通视分析为例,建立了影响模型,从而为进一步研究环境因素影响下地理信息空间分析提供了一个系统模型。环境模型与GIS的耦合将在很大程度上扩展了GIS的应用领域,促进了GIS与环境模型系统的深入发展。

The Integration of Environment Model and Geography Information System

This paper analyzed the characteristic of the environment model and GIS,discussed the advantage of the integration of environment model and GIS and the way of GIS's apply in the environment model,analyzed the three integration method between the environment model and GIS, analyzed the characteristic of all the three method,pointed out their advantage and disadvantage,then put forward a framework of GIS spatial analysis,analyzed the function of every system model,established the influence model of visibility by the example of fog and found a way to establish the framework based on the environmental influence for the future.The integration of the environment model and GIS will extend the field for using deeply,and accelerate the development of GIS and the environment model system.
