Dendrolimus houi Lajonquiere is one of the main leaf-eating insects of China coniferous wood and causes serious damage to the safety of the forest ecosystem. In this article, the temporal and spatial distribution patterns of Dendrolimus houi Lajonquiere in the Sichuan Province of China were analyzed by ArcGIS. Using the band set statistical method in ArcGIS, 28 environmental factors were divided, and it was found that Wind10, Prec7, Bio4, Bio15, Srad3, Prec2 and Srad5, these 7 factors played a key role in the distribution of Dendrolimus houi Lajonquiere. Combined with 7 species distribution models, including Artificial Neural Network, Bioclim, GARP, Climate Space Model, Envelope Score, Maximum Entropy and SVM, the potential distribution area of Dendrolimus houi Lajonquiere was simulated, and the simulation results were all greater than 0.8, low, medium, and highly suitable average areas are 96227.54 km², 66062.81 km² and 91549.23 km² respectively, occupying 52.23% of the total area of Sichuan, China. According to the simulation results, it is necessary to strengthen the monitoring of the potential suitable areas for Dendrolimus houi Lajonquiere to prevent the large-scale damage of pine caterpillars in the forests of Sichuan.
