基于组件GIS的造林决策支持系统的构架

Framework of component GIS-based afforestation decision support system

提出基于组件GIS的造林决策支持系统(ADSS)框架体系。在Windows操作环境下,运用基于VisualBasic和VisualC编程的组件GIS技术、DB技术、ES技术和DSS技术等,以林场为单位建立森林资源的基本管理平台,并在这个平台上通过各种查询、运算、逻辑判断及空间叠加、空间分析功能,实现对林场小班的造林更新决策,获得造林方案图,并以该方案为依据,对未来一定年龄期的林分生长进行预测预估,作为评价和调整原来的造林规划方案的依据,最终实现造林的优化决策。

A framework of component GIS-based afforestation decision support system (ADSS) was put forward. In the environment of Microsoft Windows, a man-machine-interface system, used as a tool for managing forest resource in a forestry center, was established with component GIS, database technique and expert system based on Visual Basic or Visual C. Through various inquiries, calculations, logic judgments and spatial analysis provided by GIS, an afforesting decision could be made and forest planning map of the working team could be obtained. In such a map the growth of a piece of forest at a certain age could be estimated and used as the foundation to evaluate and adjust the original plan, and finally an optimized decision making on afforesttion could be obtained.
