✦ Synopsis
Fossil pollen data from China indicate continued forest decline during the midto late Holocene in most regions north of the Yangtze River. The earliest forest decline can be detected ca. 5000 yr BP in the middle and lower Yellow River regions. North, northeast and northwest from this region, forest decline became progressively later, and almost no decline took place in the northernmost part of northeast China and in the remote areas of west China during the last 5000 yr. Climate changes could hardly account for the temporal and spatial patterns of the forest decline. Instead, anthropogenic disturbance may have been of overwhelming importance. Ancient agriculture and high-density settlement expanded outward from the middle and lower Yellow River regions in similar patterns to those of forest change. This study also indicates that land-use and land-cover changes may have started in the early stage of Chinese civilization in an extensive area of the country.
