Abstract: We examined the spatial distribution of Tenebrionidae in Alxa Plateau and its environmental response based on the investigation of Tenebrionidae in Alxa Plateau, combined with the temperature, precipitation and solar radiation data, using Grid-Cluster analysis, OriginPro 9.0 and Canoco 5.0 analysis software. The results showed that,with increasing latitude, the number of species rose firstly and declined gradually, with the fitting curve being a parabola. With increasing longitude, the number of species increased gradually, and decreased after the peak, with the fitting curve in approximately unimodal. With increasing altitude, the number of species increased gradually, and decreased after the peak, with the fitting curve showed a single-peak trend. Rainfall, temperature, and solar radiation significantly affected the latitudinal distribution of species richness of Tenebrionidae. Species richness followed a unimodal type with increasing rainfall, peaked in the 38°-39° N. Species richness decreased with increasing temperature and peaked in the 39°-40° N. With the increases of average monthly radiation, Tenebrionidae showed a trend of unimodal type, and peaked at about 16100 kJ·m-2·d-1 (38°-39° N). Solar radiation and rainfall were the main meteorological factors affecting the distribution of Tenebrionidae in the Alxa Plateau.
