基于MapGIS平台的阿拉善荒漠区啮齿动物群落专家系统中推理机的研究与实现

Research and implementation of the inference engine in the rodent community expert system in the Alashan desert area based on a MapGIS platform

本研究在前期研发阿拉善荒漠区啮齿动物群落专家系统的基础上,对开垦、轮牧和过牧3种不同类型生境中啮齿动物优势种子午沙鼠(Meriones meridianus)、三趾跳鼠(Dipus sagitta)和小毛足鼠(Phodopus roborovskii)相对数量与8个不同植物因子动态关系进行定量非线性分析,借助MapGIS平台,利用3种优势啮齿动物种群相对数量与8个不同植物因子组成的数据库系统、3种优势啮齿动物种的图像信息组成的知识库系统、3种不同生境下19种不同生态模型组成的模型库系统,构成啮齿动物群落中种群相对数量与植物因子动态关系的推理机,通过程序设计语言VB(Visual Basic)进行MapGIS二次开发,在专家系统中予以设计并实现。

Building on previous research and development of the rodent community expert system in the Alashan desert area,we analyzed the relative quantity of Meriones meridianus, Dipus sagitta, and Phodopus roborovskii in three different types of habitats(reclamation, rotation grazing and overgrazing) as well as the dynamic relationships(both quantitative and nonlinear) of eight different plant factors. We utilized the MapGIS platform with eight plant factors and three dominant rodents in three habitats, and a database system composed of population data, a knowledge base system composed of image information of three dominant species of rodents, and a model library system composed of 19 ecological models in three habitats, so as to form an inference engine for the dynamic relationship between the relative number of populations in the rodent community and plant factors. The MapGIS was developed using the programming language VB(Visual Basic) and was designed and applied in the expert system.
