基于MapGIS和植被数量指标的啮齿动物群落模拟专家系统的设计与实现

选择鼠害频发的阿拉善荒漠区分布面积较大的红砂+泡泡刺生境、红砂+杂类草生境和白刺生境,以夹日法记录三种生境中啮齿动物种群相对数量,利用啮齿动物种群相对数量与荒漠区灌木和草本植物之间的依存关系建立专家模拟系统,分析三种生境的主要害鼠子午沙鼠、三趾跳鼠和小毛足鼠种群相对数量与植物群落因子间的动态关系,并以MapGIS为地理信息平台,借助VB程序语言设计工具,设计阿拉善荒漠区啮齿动物群落模拟专家系统,探索植物群落与啮齿动物群落的反馈动态变化,实现利用植物群落指标预测啮齿动物群落组分及其相对数量变化的目标,为鼠害防控提供依据。

Design and Implementation of Rodent Community Simulation Expert System Based on MapGIS and Vegetation Quantity Index

In this study,Reaumuria soongorica+Nitraria sphaerocarpa habitat,Nitraria tangutorum habitat and Reaumuria soongorica habitat with large distribution area in Alxa desert area with frequent rodent damage were selected as the research objects.The relative number of rodent populations in the three habitats was recorded by the method of trap-day,and the expert simulation system was established by using the dependence between the relative number of rodent populations and shrub-herbaceous plants in the desert areas.This paper analyzed the dynamic relationship between the relative populations of Meriones meridianus,Dipus sagitta and Phodopus roborovskii and shrub-herb community factors in three habitats,and designed a rodent community simulation expert system in the Alxa desert with the help of VB program language design tool based on MapGIS,so as to explore the feedback dynamic changes of shrub-herb and rodent communities,to achieve the goal of using shrub-herb community indicators to predict the composition and relative quantitative changes of rodent community,so as to provide basis for rodent prevention and control.
