Based on field investigation and literature analysis,the species distribution and flora of the Tengger Desert are systematically studied,and the characteristics of insect communities in the desert area are analyzed.The results show that there are 819 species of insects distributed in the Tengger Desert,belonging to 16 orders,173 families and 594 genera. The fauna composition of insects is:645 species of Paleo-Northern species,accounting for 78. 75%;27 species of Oriental species,accounting for 3. 30%;and 147 species of widespread species,accounting for 17. 95%. The insect distribution area is 730 species in agricultural and forestry areas,385 species in desert steppe areas,335 species in fixed and semi-fixed sand areas,and 62 species in quicksand areas. Insect communities in the desert area are divided into three types:mobile dune type,fixed and semi-fixed dune type and desert steppe type.
