ArcGIS software was used to analyze the spatial distribution of Mid Holocene (i.e., 6.7-3.1 ka BP) human settlements and sites in the Dalian area. Their evolution was studied in depth alongside the Mid Holocene environmental background known to have existed. The results showed that: ① The number of ancient settlements in the Dalian area increased during this period. Most sites during the three periods studied were to be found 0 to 50 m above sea level (asl), with a significant increase in the number of sites located > 50 m asl during the Bronze Age. In terms of gradient of slope, all settlements were concentrated on coastal plains or in low-altitude, hilly areas on relatively gentle slopes ranging between 0 and 6 °. Settlements from each period faced in all directions, and were mainly located in river valleys or low-altitude mountain valleys with low terrains.② The proximity of ancient settlements to river courses during the Mid Holocene evolved, with Mid and Late Neolithic ....
