Abstract:
In order to study the relationship between different land use patterns and soil fertility and land degradation,the loess hilly area of Inner Mongolia was used as the object,nine soil physical and chemical indicators of five kinds of land use types including cultivated land,grassland,abandoned land,shrub land and arbor forest woodland were selected.The study calculated the soil fertility composite index and the soil degradation index of different land use types.The results showed that there were significant differences in soil indicators among different land use types.The comprehensive index scores of soil fertility of five land use types were as follows,cultivated land > grassland > shrub land > arbor woodland > abandoned land.The soil degradation index of abandoned land and tree woodland were negative,the soil degradation index of shrub woodland and cultivated land were positive.Different land uses had different influence on soil fertility,it had a good linear relationship between soil fertility comprehensive index and soil degradation index.
