| Research Abstract |
In the Wuchuan County, the middle part of the Inner Mongolia Autonomous Region, China, it is clarified that maximum gully erosion rate estimated to 25-115 cm/yr during 2003-2010 due to our observation. The gullies in this area continue to form since the middle Holocene. On the eastern margin of the Ulan Buh desert, Western Inner Mongolia, the amount of sand dune migration attains more than 1, 500～2, 800 m since ca. 8 ka, especially 1～10 m/yr in the past five decades. Under such physical environment, local farmers intensively engaged in sunflower cropping in unsustainable consciousness. We also made clear the part of desertification processes of the Hunshandake Desert, from the analysis of NDVI-value change during the recent years.
