不论局域种群的Allee效应还是集合种群的似Allee效应，对生态学的各个方面和保护生物学都有深刻的影响。

It has been shown that there are Allee-like effects at metapopulation level, which is similar to that of Allee effects at the local population level.

已有的研究表明，在集合种群水平上，也存在类似于局域种群Allee效应的似Allee效应(Allee-like effect)。

Hence, researches on influences of Allee effect s and Allee-like effects at different spacial scales on predator-prey interactions appear very important.

因此，研究Allee效应和似Allee效应对不同尺度上捕食者。猎物相互关系的影响就具有重要的意义。

However, most research has been focused on the Allee effects of local populations and both theoretical and experimental studies on Allee-like effects at the metapopulation level remain much too limited.

然而，目前的研究主要集中在局域种群水平上，关于集合种群水平上似Allee效应对生态学系统的影响，不论是理论还是实验研究都十分缺乏。

Both theoretical and field studies have indicated that there is an Allee-like effect at the metapopulation level which similar to the Allee effect at the local population level.

理论和实验研究表明，在集合种群水平上，也存在类似于局域种群Allee效应的似Allee效应(Allee-like effect)。

In this paper, I have constructed models for local population and metapopulation dynamics. Then by mathematical analysis and numerical simulation, I focus my studies on the relation between the Allee-like effects at the metapopulation level and the Allee effects at the local population level and their impacts on the stability of ecological systems.

在本文中，通过建立局域种群和集合种群的理论模型，把局域种群动态和集合种群动态结合起来，用数学分析和数值模拟分析的方法研究了集合种群水平上的似Allee效应与局域种群的Allee效应之间的关系以及它们对生态学系统稳定性的影响，并对含Allee效应的物种的自然保护提供了理论依据。

We also conclude that the equilibrium of the prey population will be enlarged due to the Allee effect of the predator, but the Allee effects of the prey may decrease the equilibrium value of the predator, or that of both the predator and prey.

如果捕食者受Allee效应的影响，则猎物种群在平衡点的密度将增大；但是猎物的Allee效应将同时减小捕食者和猎物在平衡点的密度，或者减少捕食者在平衡点的密度。
