The Middle Holocene period witnessed significant environmental and cultural transitions regarding the deceleration of sea‐level rise and the emergence of early agriculture, which profoundly moulded human–environment interactions in coastal regions. The Hemudu Culture (7000–5000 cal. a BP) is primarily distributed in eastern China coastal plains and marks a milestone in the origin of rice agriculture, and thus serves as an ideal case for examining these dramatic transitions. However, most existing studies have only focused on one particular aspect of the interactions amongst cultural evolution, subsistence strategies and sea‐level fluctuations in the Yaojiang Valley, and comprehensive understanding of cultural responses to Middle Holocene sea‐level fluctuations across the Ningshao Plain remains ambiguous. In this multi‐proxy study, pollen, phytolith and diatom remains from a high‐resolution profile of the Xiawangdu site (Hangzhou Bay, eastern China), along with a systematic collection of archaeological sites and radiocarbon dates for the Hemudu and Liangzhu cultures, were employed to assess human adaptation to the coastal environment. Coinciding with the cultural interruption between 6200 and 5600 cal. a BP, induced by Middle Holocene sea‐level transgression, Hemudu Culture diffused from the Yaojiang Valley northward to the Zhoushan Islands and southward to the Ningbo Plain, e.g. the Xiawangdu site. The regional ecological environment has experienced an evolutionary sequence from marine transgression (6200–5600 cal. a BP), to coastal lagoon (5600–5300 cal. a BP), through to freshwater wetland (5300–4300 cal. a BP). Settlements of pile dwellings and terraces were constructed to adapt to the hydrological transition from coastal lagoon to freshwater wetland around 5300 cal. a BP. In addition, evidence of both rice phytoliths and Poaceae pollen suggests that rice had already been domesticated by 5600 cal. a BP. Thus, the dispersal, settlement and subsistence of Hemudu Culture in the coastal lowlands of eastern China were largely dependent upon sea‐level fluctuations.
The eastern China coastal plain is an ideal area for studying the human–environment interaction during the Neolithic period as there are multiple Neolithic sites in this area. Located in the Ningshao Coastal Plain of the south bank of Hangzhou Bay in eastern China, the Hejia Site is part of the late Hemudu Culture sites and includes the late Hemudu Culture, the Liangzhu Culture, and the Qianshanyang Culture. Based on palynology, charcoal, X-ray fluorescence (XRF), and magnetic susceptibility (χ), combined with accelerator mass spectrometry 14C dating and analysis of the archaeological cultural layers, we explored the paleoenvironmental evolution and human activities at the Hejia Site. 1) Pollen records suggest that the vegetation type was evergreen and deciduous broad-leaved mixed forest during the Middle Holocene. Cr/Cu and low-frequency magnetic susceptibility (χlf) reveal that the climate underwent through warm and wet (Hemudu Culture Period IV)–cool and dry (Liangzhu Culture Period)–warm and wet (Qianshanyang Culture Period) periods. 2) During the Middle Holocene, the intensity of human activities, related to the transformation of the natural environment, increased obviously. The increasing Poaceae pollen (>37 μm) indicates that the ability of prehistoric humans in managing crop fields gradually increased from the late Hemudu Culture Period to the Liangzhu Culture Period. The charcoal concentration results suggest that the occurrence of high-intensity fire events during the late Hemudu Culture Period might be caused by the slash-and-burn operation, while those that occurred during the middle Liangzhu Culture Period might be caused by the increasing fire demand owing to the greater ancestors’ lives and production activities in the Liangzhu Culture Period.
