摘　　要：综述了数学和统计学对哺乳动物种群系统生态学过程与环境随机过程交互作用的研究进展,以及种群波动同步性的Moran原理及效应。自然种群最普遍的现象是其数量在时间和空间上的变异性。在不同种群之间,种群大小的波动方式存在显著的差异。阐明和理解这种差异,探讨其随环境条件而改变的潜在规律,是种群和群落生态学的主要挑战之一。种群变异性存在空间分量,在相对大的距离内,种群的波动常同步发生。对种群内部密度制约过程与诸如环境变异性等外部因子交互作用的检验正在成为哺乳动物种群系统生态学领域关注的论题。In this paper, we briefly review the progress in the way of temporal and spatial variability in mammalian population system, and Moran's theorem and Moran's effect to the synchronization of population fluctuations. One of the most universal phenomena of all natural populations is their variability in numbers in space and time. However, there are distinguishable differences among populations in the way the population size fluctuates. One of the major challenges in population and community ecology is to explain and understand this variety and to find possible rules that might be modified from case-to-case. Population variability also has a spatial component because fluctuations are synchronized over relatively large distances. Recently, this has led to growing interest in how internal processes such as density-dependent interact with external factors such as environmental variability.
