The Anthropocene and the landscape of Confucius: A historical ecology of landscape changes in northern and eastern China during the middle to late-Holocene.

The Yellow River catchment of northern China was central to the rise of complex societies from the first Neolithic farmers through to early states and empires. These cultural developments brought with them rising populations and increasing intensity of land-use. This region provides an important record of landscape changes that mark the development of the Anthropocene in China. Geoarchaeological research in the middle reaches of the Yellow River catchment of Henan Province and eastward to the Si River drainage of Shandong Province illustrates human impact on vegetation and hydrological systems dating back at least until the middle Neolithic Yangshao Period in the mid-Holocene, ca. 7000 yr BP. This research provides geomorphological evidence that early human impact began in the Yangshao period with deforestation, soil erosion, and increased alluviation in the upper catchment of the Yiluo River. The increased alluviation allowed small-scale Neolithic farmers to intensify and supplement their production with rice paddy farming. Further east along the Si River of Shandong Province, Neolithic Dawenkou farmers were intensifying production by taking advantage of the already moist floodplains, but had little impact on the surrounding forests and hillslopes. At the beginning of the Zhou Period (ca. 1000 BCE), farmers along the Si River at Qufu began to intensify production by digging canals into the floodplain, and deforestation of the hillslopes led to the beginnings of widespread floods and silty floodplain buildup, culminating in the massive destructive floods of the later Han Period characterized by thick sand beds.
