【Abstract】 Based on data from 16 plots ,the species richness, evenness and species diversity of grassland typesin the middlezone of northern slop of TianShan Mountainswere discussed. Theresults showed there were evident differences among the diversity indices of grassland typesin UrumqiRiver. The biodiversity is the highest in the Alpine meadowand the lowest in the Montane desert. These differences were closely related to the ecology habitant and environment.更多还原
