For the sake of realizing some special functions in spatial analysis of GIS, it is necessary to covert irregular vector polygon into regular grid.

在实际的GIS空间分析过程中，为了更加简便快捷的实现某些特定的空间分析功能，常常需要将不规则的矢量多边形区域转化为规则的格网区域。

Therefore, the model of SD with non-spatial dynamic simulation melted with spatial analysis of GIS technology can make full use of their advantages.

因此，在以空间分析为特色的GIS技术环境下融入非空间动态模拟的SD模型，可充分利用两者的优势。
