| Abstract: | Jianghan Plain, a very famous plain for its abundant products and river-lake cross landscape, is the place where Yunmenze palaeolake existed. The Miancheng area is the sedimentation center of Jianghan Plain with lowlying topography. Human activities on this area were comparatively late in history. A 56. 18-m-core was collected in Miancheng of Jiang plain in Oct. 1992. According to the sediment lithology, cultural remnants, ~(14)C chronology and human-derived environmental proxies, e.g. pollen, frequency magnetic susceptibility and chemical element phosphorous, the temporal sequences of human activities in Miancheng area since the mid-late Holocene and its relation with palaeoenvironment are discussed in this paper combined with the study on temporal-spatial distri- bution of cultural relics in this area. The results have shown that the climate was warm and wet in 6. 7 - 3. 5 kaBP, and the core site was characterized by fluvial depression or shallow lake environment. In 2. 5 - 1. 7 kaBP, the lake was stable and there was no human dwelling, but was slightly influenced by human activities in surrounding area. In 3. 5 - 2. 5 kaBP, the influence of human activities was enhanced. The core site was exposed since 1. 7 kaBP and there were human residents in this area. All above suggest the human being's subjection to nature in the era of poor productivity. i. e. human being withdrawing with the lake transgression, and marching with the lake regression. |
