摘要
针对一类稀疏效应下的生态系统模型 x =x2 (1 -Ax) (1 +Bx2 ) -x2 y y =y(Dx2 - 1 )进行了数学研究 ,得出了一些重要性质的判别准则 。
In this paper, we discuss a class of predator-prey system with sparse effect =x 2(1-Ax)(1+Bx 2)-x 2y =y(Dx 2-1) we obtain the sufficient conditions for some important property and give the appropriate bilogical iuustrations.
