Although archeological excavations in the region have been on the rise, providing insights into the regional cultural sequence, research on the evolution process of sites from a twin-city perspective remains limited. In this study, geographic information system (GIS) analysis was used to examine the spatiotemporal distribution of settlements in the region from the Neolithic to Bronze Age. Correlations between the distribution of archeological sites and environmental factors and the directionality of human mobility were wxplored. The results indicate that settlement distribution is strongly influenced by environmental factors. Ancient societies considered moderate elevation, convenient distance from rivers without flooding risk, and suitable soil for cultivation as the three main factors when selecting settlement sites. Sites respond to environmental change in different periods based on various factors, such as the slope, aspect, distance from the river, and soil type, and are mainly located in areas with slopes &lt;10°, facing south or west, and within a 2 km radius of rivers. As human reliance on water resources increases with improved productivity, limitations imposed by the natural environment decrease. Notably, since the Neolithic period, soil fertility, water, and topography have been key factors affecting the distribution of settlements. Compared with single factors, interactions among the factors exhibit greater explanatory power for the regional spatial distribution characteristics of settlement sites in the Sichuan-Chongqing region. The distribution of sites from the Neolithic Age to the Western Zhou Dynasty show a decrease in migration patterns along rivers in the Eastern Zhou Dynasty in the Chongqing region, while also demonstrating enhanced clustering. In addition, the dual-center trend intensified gradually in the Sichuan–Chongqing region.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"724 ","pages":"Article 109726"},"PeriodicalIF":1.9,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sedimentary core, retrieved at 40°S - 57°W from the outer shelf, documents the environmental evolution of the coast during the Late Glacial-early Holocene, influenced by significant post-Last Glacial Maximum (LGM) sea-level changes. Between the LGM and 15 cal ka BP, an isolated coastal lagoon was established. It was characterized by reducing and low-energy conditions. Microfossils with continental and marine affinities suggest a brackish environment influenced by continental runoff, originated from increased precipitation in southeastern South America during the Heinrich Stadial 1. Subsequently, between ∼15 and 14 cal ka BP, the environment rapidly evolved into a coastal lagoon with marine connection. This change coincides with the Meltwater Pulse 1 A, which caused a rapid sea-level rise, integrating the lagoon with the open marine environment. The continuous rise in sea-level allowed the formerly isolated lagoon to be connected to the open sea around ∼14 cal ka BP, forming a mesohaline, tide-dominated paleobay. This vegetated tidal flat was characterized by environmental stability and a high diversity of ostracods and foraminifera. Then, around 13.7 cal ka BP, a storm-dominated shoreface is interpreted, indicating high-energy and fully marine conditions. A coarse bioclastic interval reflects repeated storm events on the shelf, mainly during the Younger Dryas stillstand and the Meltwater Pulse 1 B, which marks the last rapid pulse of middle and outer shelf inundation. The holocene sediments represent typical outer shelf conditions, characterized by relict sands formed by the reworking of pleistocene continental and marginal marine sediments.

Abundant evidence suggests that the central government effectively managed and controlled the southwestern region during this period. Nevertheless, in-depth exploration is necessary to delineate the dynamic interplay between environmental changes and social development. This study conducted chronological, grain-size, and spore-pollen analyses on sediment from the T8SW section at the Chengba site in southwestern China, aiming to investigate the hydrology, vegetation, and climate changes during the Han and Jin Dynasties (202 BC-AD 420). The WAPLS (Weighted Average Partial Least Squares Regression) method was also employed to reconstruct the paleoclimate quantitatively. The results showed that in the early and middle phases of the Western Han Dynasty (202-48 BC), this area was characterized by a subtropical-warm temperate mixed forest and grassland landscape. The Jinguan relic is nestled within a serene riverine bay and wetland expanse, boasting lush vegetation. During the Eastern Han Dynasty to the Jin Dynasty (AD 25–420), with the cooling of the climate and the drying of the sedimentary environment, this area transformed into a warm temperate forest and grassland landscape. The position of the Jinguan relic gradually emerged out of water, evolving into high floodplains and terraces with sparse vegetation. Upon entering the Eastern Han Dynasty, a substantial alteration occurred in pollen concentration and composition, which might have been associated with intricate variations in hydrological environments, climate change, and human activities. Quantitative reconstruction approaches have reconstituted the annual precipitation (Pann) and mean temperature of the coldest month (MTco). These data reveal that the climate in the area experienced a ‘warm and humid - cold and dry - warm and humid' cycle from the Han to the Jin Dynasty. Notably, a significant dry climate event occurred around the transition between the Western and Eastern Han Dynasties, approximately AD 8–25. Archaeological and documentary data suggest that changes in human activities within the area were closely linked to variations in vegetation and climate. The shift in fluvial hydrological regimes under the cooling and aridification trend during the Eastern Han Dynasty likely served as the primary catalyst for both the architectural transition from stilt-based to ground-level construction methods, as well as the significant rise in both the quantity and depth of water wells. Simultaneously, the large-scale urban construction and the boom in the mining and smelting industry during the middle and later periods of the Eastern Han Dynasty likely led to selective logging.

The temporal record of salinity and productivity tracking species combined with data from other ISM records, suggests several abrupt events in the monsoonal precipitation in the last 15 cal ka BP. The salinity tracking species show higher abundance during the early Holocene, 6.5 and 2 cal ka BP, pointing towards enhanced river runoff and direct precipitation associated with strong ISM during these periods. Whereas productivity species were abundant during Younger Dryas (YD; 13.6–12.6 cal ka BP), 7.7–5.3 cal ka BP, and its abundance decreased during the early Holocene and late Holocene periods, indicating weak water column stratification associated with reduced ISM. Our data indicate a considerable amount of freshwater runoff during Bølling/Allerød (B/A), early and late Holocene and comparatively less river influx during late glacial periods and YD. This suggests that monsoon intensification occurred during the early Holocene, and a weakening trend was seen during deglacial periods. The increased productivity events may reflect periods of weak stratification, which is possibly driven by weak ISM.
