| 摘 要： | 现有的地理信息系统软件一般没有考虑时间和空间多维因素，难以处理时空多维地学现象。而空间过程模拟是地学现象研究的主要手段。本文对空间过程模拟的数学模型、空间过程模拟模型的特点、现有GIS数据模型的局限性进行了分析，提出用快照序列模型和时间参数模型支持过程模拟的方法，并结合地震动过程模拟进行实例分析。

| Abstract: | Current Geographic Information System (GIS) software does not support the manipulation of multi dimensional spatio temporal data, therefore it is difficult to deal with the geographic phenomena with spatio temporal multi dimensions. Spatial process simulation is the main way to study the geographic phenomena. In this paper, a discussion is conducted about the mathematical model of spatial process simulation, the characteristics of spatial process simulation models, and the shortcomings of the present GIS data models. A method using the sequent snapshot approach and the temporal parametric model to support spatial process simulation is put forward, and a practical example is analyzed with combination of seismic dynamic process simulation. |
