Other AbstractIn order to reveal the long-term effects of resettlement and construction on soil nutrients in the middle part of the three Gorges Reservoir area, three typical land use patterns (cultivated land, orchard and woodland) were selected in different landform types of resettlement areas in the middle of the reservoir area. By means of principal component analysis and Nemero index method, the characteristics and interannual variation of soil nutrients in different regions from 1998 to 2015 were revealed. The results showed that the total soil nutrient level was low in the resettlement area of the middle part of the reservoir area, and the characteristics and changes of soil nutrients in different geomorphological types and land use patterns were different. In 2008, 2012 was the lowest and highest point of soil nutrient comprehensive index, the soil nutrient index of strip low mountain area was the highest, that of shallow hill area was the second, and that of monoclinic deep hill area was the lowest, but the range of change was larger. The change of soil nutrient index in cultivated land was significant, but the forest land and orchard were more stable.
