摘　要：摘　要：Michael Rosenzweig于1971年首次提出“富食悖论”这一概念：在简单的被捕食者－捕食者系统中，随着营养物质供应的增加，系统变得不再稳定，并产生大振幅波动，最终导致系统内的物种灭亡。然而，许多实验结果并不支持Rosenzweig的理论。综述“富食悖论”的定义、理论和实验研究，同时综述各种解释实际与理论之间矛盾的机制，最后探讨“富食悖论”的研究前景。

Abstract: Abstract: The term “paradox of enrichment” was coined by Michael Rosenzweig in 1971. In simple prey-predator models， increasing food availability to prey destabilizes the stable system and produces large amplitude population oscillations leading to species extinction. Subsequently， a great number of experimental studies have been conducted to test this theory， while many results do not support Rosenzweig{$39}s theory. In this study， we review the definition of the “paradox of enrichment”， its theoretical and experimental cases， and give a brief overview of the mechanisms underlying the discrepancy between theoretical expectations and experimental observations. Finally， we consider future directions for research on the "paradox of enrichment".
