摘要
在文[7][8]的基础上,分析一类食饵具常数收获项的Ⅱ类功能反应的捕食系统.通过对两鞍点分界线相互位置仔细的分析,得到了比较完备的定性结论,特别是第一次在生态系统的讨论中得到了三个极限环的存在性.
The paper and its sister paper mainly investgate a prey-predator system of bolting'sⅡ functional response with havesting term. By studying the change of relative situations of the separatrixs of two saddle points, a comparative completely qualitative conclusion is given. For the reasion of space,the part of the existence of the limits cycles is left to the next paper.
