摘要
The relationship between succession and stability in plant community was discussed based on redundancy theory.We regarded that:① Successions are recombination of components (species,individuals,or patches) on paralleled structures.In succession,simple paralleled redundancy structure in early stage changes into multiple one in later stage.② Community stability is redundancy structure stability.Every succession stage is stable,for replacement of species does not mean instability.③Resistance is related with redundancy structure and biological characters or longevity of species.In general,communities with complicated redundancy structure and long life span species are stronger in resistance than communities with simple redundancy structure and short life span species,especially in early stages.④Resilience is actually the rate of redundancy recruitments.Community redundancy structure will not be destroyed even in communities with simple redundancy structure and short life span species,if there are redundancy recruitments.⑤Resistance,resilience,persistence and variability are redundancy phenomenon at levels of individual,species and community.They should not be defined as 4 components of community stabilities.⑥ Succession speed or pattern,dominants,species diversity and so on have no innate relation with community stability.
