Species and species diversity in relation with restoration and persistence of degraded ecosystem functions

Abstract

Abstract: Species diversity is an important character of an ecosystem,and keeps it to function.Species diversity, their communities provide human with essential ecosystem services,including nutrient cycling,biological productivity,trophic function,etc.Species diversity is tightly related with the ecosystem's ability to withstand stress, disturbance.Increasing biodiversity could enhance system stability.Compared to individual species, species number,functional group, functional diversity impose larger impact on system functioning,and are good approaches used to measure stability, to predict community change.Several forms with which the species act on ecosystem functioning were proposed, discussed in this paper.Understanding the relationship between species diversity, ecosystem function could guide the practice of restoring degraded ecosystem, maintaining its functions.Particularly,it provides basic ecological theories for “species assemblage” at initial stage of restoration.
