【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.
