The origins and maintenance of species diversity is a core of biodiversity. Numerous hypotheses address this topic. The maintenance of species diversity in community is divided into increasing process ( speciation , invasion and colonization) , decreasing process(extinction) and species coexistence. The internal cause of species coexistence is the different biological and ecological property of species , external cause is the habitation heterogeneity of community. The habitation heterogeneity of community is the basis of species diversity and drives the community organization process. Patches mosaic structure of community is due to gap formation and lead species diversity. Patches mosaic is the basic property of community which makes the structure and function of ecosystem prolonged maintaining. The patches mosaic pattern and its role in maintenance of species diversity and productivity for the Monsoon evergreen broadleaved forest in Dinghushan Biosphere Reserve have been discussed.
