Abstract:

Based on the ArcGIS10.3 platform, the elevation, slope, aspect and the river distance of the Holocene settlement sites in the south bank of Laizhou Bay are analyzed, the temporal-spatial distribution and evolution characteristics of the settlement sites are obtained. Combined with the environmental background in the South Bank of Laizhou Bay, to explore the influence of Holocene environmental evolution on the distribution and evolution of settlement sites. The results show that: 1) The quantity, frequency and proportion of the number of settlements in the study area are firstly increasing and then decreasing in a V-type (asymmetric) trend. 2) The distribution of the site has a certain regularity, almost all the sites are located in the elevation of the range of 0-29 m in the area, while the Dawenkou culture period is 10-29 m. This difference is closely related to the Huanghua transgression of the middle Holocene. From the slope, the settlement sites are mainly distributed in the range of 0°-4° in the gentle areas; from the aspect, the ancients are mostly concentrated in the direction of south, southeast and southwest. From Houli culture to Longshan culture, the influence of river distance to settlements gradually decreased, and the ability of the ancients to adapt environment gradually increased. 3) 8.5-6.9 ka B.P., the climate goes into warm, and the cold and warm fluctuations, dry and wet alternately, thus Houli culture gets to be developed; 6.9-4.5 ka B.P. appears a brief cooling, but the overall more moderate, superior natural conditions promotes the growth of Dawenkou culture; 4.5-4.0 ka B.P., comparied with Dawenkou culture period, climate conditions are slightly drier, but Neolithic culture is still further development, and entering the peak stage in the Longshan culture period; around 4.0 kaBP, the climate suddenly changes and emerges violent cooling events. The range of change exceeds the human adaptation ability, leading to the decline of Longshan culture. 4) Seawater intrusion restricts human activities, but the formation of ancient lakes and rivers creates the natural conditions for the improvement of the quality of life for the ancients.

Key words: the south bank of Laizhou Bay, Holocene, the temporal and spatial distribution of the site, environmental background
