|Background, aim, and scope In view of the fact that Hunan is one of the cradles of Neolithic culture in the middle reaches of the Yangtze River, in order to better understand the relationship between man and land in Neolithic period, it constructs a comprehensive evaluation system of fuzzy index of human settlement environment in Neolithic settlement sites with seven indexes: elevation, slope, aspect, water, landform, soil and vegetation distribution type. Materials and methods In this paper, the weight of each factor is determined by using the factor detection method of geographic detector, and the weight value of each factor is weighted and superimposed and classified by comprehensive grade type in ArcGIS. Finally, it gets the evaluation results of the suitability of human settlements in Hunan Neolithic settlement sites. Results Altitude and water factors account for the highest weight value, settlement sites are distributed along rivers, which are mainly distributed around 5—413 m, accounting for 89.11% of the total. Settlement sites distributed in soil suitable for cultivation account for 82.94% of the total, they are mainly distributed between slope and plain. The area with moderate livability or above is 185900 km2, accounting for 87.77% of the total area. Discussion Since the ancient people used walking as their mode of transportation on land, they chose to live in low-altitude and south-facing plains and hills for daily communication and farming. Living near water can not only facilitate daily water intake and fishing, but also play the role of transportation or direction guidance. Plain provided convenient conditions for the agricultural activities of the ancients, while settlements were more inclined to the hills because of abundant animal and plant resources, which could reduce the risk of floods and beasts. Conclusions The living style of agriculture, gathering and hunting prompted them to choose to live in the plain and hills with rich resources and close to the water. Recommendations and perspectives The relationship between man and land in prehistoric settlements is a symbol of harmonious coexistence and gradual development between people and the environment in the early days. With the development of agriculture and population growth, it is required to further study human factors such as settlement expansion and social nature change.
