The research objects of human settlement suitability evaluation are mostly cities or villages, and towns are rarely used for analysis and evaluation. This paper takes Tianpeng town of Pengzhou city as the research area, divides the human settlement environment suitability evaluation factors into three-factor layers, 18 index layers, combined with relevant standards and literature data. Analytic hierarchy process (AHP) is used to obtain the weight of each factor, and uses ArcGIS to calculate with buffer analysis, overlay analysis and other spatial analysis methods, and the evaluation results of human settlement in the study area are obtained. The results showed that unsuitable and particularly unsuitable areas accounted for 25.13% are mainly distributed in the southeast and southwest, and more suitable areas accounted for 74.87% are mainly distributed in the middle and east.
