This paper analyzes the ecological niche of grasshoppers in the grassland of Tacheng-Emin Basin,in order to provide a theoretical basis for grasshopper disaster monitoring,management and ecological balance protection. In this study,the spatial ecological niche of grasshoppers in the alluvial plain,piedmont pluvial sloping plain and mountain area in the Tacheng-Emin Basin was analyzed. The related parameters such as grasshopper dominance,community composition difference,Levins niche width,Shannon niche width,and Pianka niche overlap were obtained. The results showed that: A total of 1 023 grasshoppers of 19 species and 6 families were collected in the three terrains. There were differences in dominant species,common species,and rare species in different terrains. The grasshopper community composition was significantly different between alluvial plain and piedmont pluvial sloping plain and mountain area. Oedaleus decorus decorus,Dociostaurus tartarus,Calliptamus italicus,Dociostaurus kraussi kraussi and Calliptamus coelesyriensis had wide ecological niches and overlapped with other grasshoppers. There were many species of grassland grasshoppers in Tacheng-Emin Basin,and most dominant species of grasshoppers had strong ability to utilize spatial resources and fierce competition. More efforts should be made to monitor the dominant hazard species,and the rare species in the piedmont pluvial sloping plain of foremountain diluvial should be protected to ensure biodiversity.
