摘　　要：为了天然草原的生息繁衍和可持续发展,针对目前我国草原严重受损的现状,研究了人类活动对草原生长状况的影响,建立了草与食草动物两种生物相互作用的生态学模型,对其进行了深入分析;此后考虑到人为破坏行为对草原生物链的影响,对模型作了进一步改进;巧妙地将模型中的非线性微分方程组线性化,对模型求解;应用Matlab软件对草原的命运予以仿真;最后得出重要结论,对草原的修复及保护有重要参考意义。For the reproduction and sustained development of natural prairie, and for the current situation that the prairie of our country has been damaged greatly, the influence of human beings' activities on the prairie was researched into and an ecology model was set up, in which the grass and herbivores interact with each other. Considering the influence of artificial destruction on prairie's biology chain, the model was improved and the differential equation series of the model was linearized to figure out the result. MATLAB software was applied to emulate the destiny of the prairie and the important conclusion was drawn, that has great significance for the rehabilitation and protection of our prairie.
