The living environment is the foundation of human survival and development, and fundamentally restricts the concentration level and distribution pattern of regional population. This article selects terrain undulation to analyze the terrain suitability of the living environment in Lincang City. Using ArcGIS 10.2 software and the mean change point analysis method, the optimal analysis window size was determined to be 0.2025 km2. Based on this, terrain undulation was calculated, and regional differences in terrain undulation were analyzed for each township. Using SPSS software, correlation and regression analysis were conducted on the average population density and terrain undulation of each township. The R2 value in the correlation analysis was −0.505, and a significant negative correlation was found between the two. The regression analysis followed the inverse curve model, with an R2 value of 0.859. According to the terrain undulation, the suitability of living environment terrain is divided into 5 levels. The terrain undulation value of the height suitable area is less than 1.5, accounting for 41.19%;The terrain undulation value in the moderately suitable area is between 1.5 and 2.0, accounting for 36.34%;The terrain undulation value in the low degree suitable area is between 2.0 and 2.5, accounting for 19.28%;The terrain undulation value of the critical suitable area is between 2.5 and 3.0, accounting for 3.03%;The terrain undulation value in the unsuitable area is ≥ 3.0, accounting for 0.16%. Analysis shows that the population of Lincang City is mainly distributed in relatively flat dam areas.
