Abstract: Taking Zitong County of Sichuan Province for an example, researches were conducted on effects of different land use types on soil nutrients by use of the method of soil sampling and laboratory analysis. The result indicated that the different land use types had significant impacts on soil nutrients. The content of soil organic matter and soil N would decline in sequence from paddy land, forest land, dry land to grassland. The content of soil total P and available P would decline in sequence from dry land, forest land, paddy land to grassland. The content of soil total K would and available K decline in sequence from paddy land, dry land, forest land to grassland.
