Jiangsu Kunshan Site In Ginger Sporopollen Archaeological Research With The Environment

Human existence and development are closely linked to Holocene environment evolution. Environmental archaeology is an important field in PAGES to study Holocene environment evolution and the interaction between human and nature. Applying environmental analysis methods to archaeology is helpful to resume the specific background of human civilization. It is significant to understand, coordinate the human-earth relationship and predict the future development trend of the environment.Jiangli Site is the study object in this article. It is located in kunshan, Suzhou, Jiangsu Province, in the east of Taihu region. Based on excavated materials, this article chooses sporopollen analysis as the main method, coordinates with archaeology, draws support from AMS14C dating to cultural layer, assists by grading analysis and diatom records. According to the Holocene environmental background in Yangtze River Delta and related archeological evidences in this region, this article resumes the early-mid Holocene paleoenvironment in the east of Taihu region.Furthermore, from the viewpoint of geography, archeology, history and etc, this article reveals the living environments and cultural connotations in Neolithic, emphatically discusses the Holocene environment changes and the temporal spatial distribution of archaeological sites in Taihu region, then researches interaction mechanisms between Neolithic cultural development and environmental factors such as eustatic changes, delta landscape evolution.Based on sporopollen records, excavated materials and other indexes in Jiangli Site and other research findings in other Neolithic sites, three primary conclusions are obtained as follows:1. Analysis of sporopollen, grain size and diatom of Jiangli Site indicates that from the Majiabang culture to the Liangzhu culture, the surroundings kept to be wet land or network of rivers. It was stable and feasible to live in and cultivate for human beings.2. Sporopollen assemblages, archaeological remains and unearthed relics demonstrate that on the whole, paleoenvironments and paleovegetations were accordant in Jiangli Site, Chuodun Site and Caoxieshan Site.3. Holocene eustatic changes and Yangtze River Delta development are significant driving forces to the evolution of Neolithic culture in the east of Taihu region. By a combination of the two forces, the sea land position was stable, Lacustrine environment and shallow water wetland was formed, providing a stable environment for culture evolution. Neolithic period was a time of plenty in the east of Taihu region.
