Study on Floristic and Ecology of Species Endemic to Xinjiang

In Xinjiang,the environmental complexity brings on species diversity.The results showed that there are 268 endemic species in 119 genera of 38 families in Xinjiang.They are rather indigent and origin younger but most of them are distributed in mountain system.So we should protect these key endemic species and their sensitive occurring areas.In order to understand and investigate Xinjiang flora's characteristics,origin and evolutive rule,the floristic and ecological characteristics of endemic species are studied in present paper.
