松嫩平原西部草原生态环境专家系统开发与应用

Study on the Exploitation and Application of Grassland Eco-environment Expert System in Northern Songnen Plain

我国草原生态环境日益恶化,要求加快研究进度,而培养专家周期长,寻找草原环境评价专家的替代或复制品就成了当务之急。笔者在听取大量专家意见并详细分析了相关资料后,通过快速原型与增量式开发建立了松嫩平原西部草原生态环境专家系统。本专家系统使用功能强大的VisualC++完成数据库的建立、知识的表示、推理机的设计、解释的给出和人机交互界面的形成,实现了数据信息的可视化、图形显示、结果输出以及其它系统功能。它包含大量的松嫩平原西部草原现状资料、遥感解译图及系统的环境现状评价、适宜性评价、土地退化程度评价等模块。通过在长岭县、大安市的应用测试,证明该系统运行稳定,结论正确,应用前景广阔。

As the grassland eco-environment is getting worse in our country, it calls for the study schedule being fasten, while the periods to bring up experts is too long, so it is urgent to find a reproduction. After listening to a great deal of experts, and referring to the relative information, Songnen Plan Grassland Eco-environment Expert System (GEES for short) was built up through speedy antitype and supplement exploitation. VC++ was used in the GEES to complete the database building up, the knowledge express, the reasoning mechanism design, explain supply and the interfacial formation between man and the computer, and to achieve the visibility of the data, figure show and result export etc. as well. There is plenty of information of status quo and RS separated map in Northern of Songnen plain, and several module of systemic estimation on environment status quo, feasibility and soil degradation degree. After the application to Changling City and Da'an County, the GEES is proved to be stably running, can reach correctly result, and it will be widely used in future.
