- Abstract:
-
Xubao site is located in the northwest of Henan and southeast of Shanxi Province, and is an important Neolithic site of the Longshan period (5 000—4 000 aBP). The landform distribution law in Neolithic sites of Qin River downstream areas, grain size characteristics in Xubao profiles and historical deposition rate during the study period showed that human of Yangshao culture (7 000—5 000 aBP) lived on Qingfengling hill or loess tableland on alluvial plains. During the late Yangshao or early Longshan culture (5 000—4 000 aBP) period, the bed of Qin River was cut down and the human of Longshan culture were able to live on the alluvial plains since then. From Western Zhou Dynasty to the early Western Han Dynasty, Xubao profile indicated that the stability of deposition and particle size characteristics of section speculated that Xubao site was a high floodplain geomorphic position. In the late Western Han, Xubao site had experienced a large flood again, floods spread all over the ground of the site and Xubao was abandoned again. From Western Zhou Dynasty to the Western Han Dynasty, the deposition rate was about 0.1 cm/a, deposition rate was about 0.2 cm/a in Western Han Dynasty, deposition rate was about 0.1 cm/a in Song Dynasty, indicating the expansion of humankind activities during the Western Han Dynasty, population growth of the Western Han Dynasty and the frequent economic activity as well as agricultural technology progress, accelerated serious soil erosion in the Yellow River Basin. Xubao profile can well reflect the erosion process and the deposition characteristics in the historical period.
