摘　　要：研究了一类具有B-D功能反应且满足齐次边界条件的捕食-食饵模型共存态的存在性,运用不动点指数理论,得到了共存态存在的充分必要条件。In this vestigated, which index theory, the paper, a predator- prey model with Bedding -DeAngelis functional response is in- is subject to homogeneous Dirichlet boundary conditions. Based on the fixed point necessary and sufficient conditions for existence of coexistence states are found.

关 键 词：捕食-食饵模型 B-D功能反应 共存态 不动点指数
