植物种群大尺度空间动态的类型及其特征分析

Analysis and Introduction on the Types of Large-scale Dynamics of Plant Population

植物种群空间动态是植物种群生态学也是空间生态学的焦点,它也是生物物种保护及植被保育的理论基础。本文对种群空间动态的重要理论进行了简要评述,重点介绍了Freckleton等提出的植物种群空间动态分类系统,对各个类型结合实例进行了说明。该系统将植物种群空间动态分为6个类型:1)Meta-种群,2)区域集合,3)空间扩张种群,4)空间结构化局域种群,5)空间非结构化局域种群,6)局域种群。

Dynamics of plant population is the focus of plant population ecology and spatial ecology, It is also the theoretical fundamental of conservation of species and vegetative. In the article we introduce important theories of the spatial dynamics of population, and R. P. Freckleton & A. R. Watkinson s classification system of the dynamics of plant population . Their system classified the dynamics into 6 types, i. e. (1) metapopulations, ( 2 ) Regional ensembles, ( 3 ) Spatially extended population, (4)Spatially structured local populations,(5)Spatially unstructured local population, (6)Local population.
