了解种群进化同步的原因是生态改善的一个重要问题。本文提出了一个由两个相关环境噪声驱动的Lotka-Volterra模型,并通过理论分析和直接仿真证明了噪声相关能引起互补者的同步。互种时间序列表现出类混沌涨落,这种涨落与噪声相关性无关,但互种比的混沌涨落随噪声相关性而减小。定义了一个描述混沌涨落的定量参数,为测量完全同步发生的时间提供了一个很好的方法。

英文摘要:
Understanding the cause of the synchronization of population evolution is an important issue for ecological improvement. Here we present a Lotka-Volterra-type model driven by two correlated environmental noises and show, via theoretical analysis and direct simulation, that noise correlation can induce a synchronization of the mutualists. The time series of mutual species exhibit a chaotic-like fluctuation, which is independent to the noise correlation, however, the chaotic fluctuation of mutual species ratio decreases with the noise correlation. A quantitative parameter defined for characterizing chaotic fluctuation provides a good approach to measure when the complete synchronization happens.
