Abstract:This paper analysed synthetically landuse and 5 nutrution factors of soil fertility in the 1980s and 1990s in Shizishan region in Wuhan city, the change characteristics of landuse construction and soil fertility in this area were illustrated generally. Soil fertility assessment was regarded as focal point, four kinds of fertility assessment models were put forward, and the best model was selected and the soil fertility in this area was graded and assessed by the best model in this area. The results indicated that the fertility of forestry land, vegetable land and paddy was going up and the fertility of dry land and orchard land was going down from 1981 to 1995; the change characteristics of landuse construction were that the areas of vegetable land, water, buildings and orchard land were increasing and the areas of the crop land and nudeveloped land were declining.
Keywords:landuse construction  soil fertility  model  assessment
