Popis: The lower reaches of the Minjiang River are located in an area of land-sea-air interaction. It is not only a sensitive area concerning environmental evolution, but also a hotspot for archaeological research on the southeast coast of China. Exploring the scope of ancient human activities and the evolution of land-use patterns is of great significance for understanding the development of human-land relations. By generating various cost surfaces of sites through GIS cost distance analysis and combining with the site catchment theory and method, we comprehensively analyzed the human activity range and land-use pattern in every cultural period from the Neolithic to the Bronze Age in the lower reaches of the Minjiang River and reconstructed the potential population in each period of the region. The results show that: (1) the area of site catchment, available and actually developed land increased from the Keqiutou to Huangtulun culture period in the lower reaches of the Minjiang River. Chronologically, the area of the site catchment continues to grow from 212 km2 to 4,858 km2, the accessible land area increased from 261 km2 to 7,599 km2, and the land area that was actually used by ancient humans continuously increased from 173 km2 to 3,914 km2. (2) With the development process of culture, the land-use intensity of prehistoric humans in the region first increased and then decreased by 81.58%, 92.95%, 87.99%, 79.33% and 80.57%, respectively, and the degree of land development was reduced, which may be related to the development and progress of productive forces. The frequency of ancient human exchanges can be represented by the ratio of the number of sites in the overlapping site catchment to the total number of sites in the same period (87.50%, 60.00%, 66.67%, 92.54%, and 97.81%, respectively). (3) The reconstruction results showed that the potential population in the area continued to expand, with substantial population growth in the lower Tanshishan-Tanshishan and Huangguashan-Huangtulun transitional periods. It was inferred that there was a relationship between population pressure and culture succession.
