对西北某荒漠地区啮齿动物的群落稳定性进行分析研究.通过建立GM(1,1)数学模型,辅以SPSS统计分析,预测啮齿动物在不同的干扰条件下各自的数量变化趋势;采用神经网络算法,结合Matlab模拟仿真,分析啮齿动物群落多样性受外界干扰的影响程度.合理地分析并预测出该地区动物群落的变化趋势,从而分析得出该地区啮齿动物群落的稳定性.%The stability of rodent community in a desert area of Northwest China is analyzed. By GM(1,1) statistical analysis mathematical model, SPSS predicts their respective change trends of the numbers of different rodents in different disturbance con-ditions. Combining Matlab simulation with neural network algorithm, the influence of external disturbance on the diversity of ro-dent community is analyzed. The integration of the two methods can more reasonably analyze and predict the change trends of ani-mal communities in the area, so as to get the stability of rodent community in this area.
