具有污染和捕获影响的一类广义Logistic种群的生存分析

Analysis on the Existence of a Class of General Logistic Species Community with Pollution and Capture Effect

利用比较原理,对一类广义Logistic种群的生存状况进行了深入讨论,得到了种群β-生存和在有限时间内零绝灭的充分条件.

This paper makes a thorough discussion on the existence of a class of general Logistic species community by comparability principle. It gives sufficient conditions for β-existence and zero extinction in finite time.
