Research on soil fractal feature of abandoned farmland-A case study from Yijinhuoluo County, Inner Mongolia Autonomous Region
弃耕农田土壤分形特征研究—以内蒙古自治区伊金霍洛旗为例

The changes of soil granularity and its fractal features of the abandoned land in Yijinhuoluo County,Inner Mongolia Autonomous Region in different years were studied.The results show that the soil with less fine particles has less fractal dimension and vice versa.The particle size less than 0.025mm has obvious exponential relation with fractal dimension,reflecting the degree of the land desertification.There also exist remarkable relations among the organic matter,nitrogen of the soil and fractal dimension.Therefore,the soil fractal dimension can be used as an important and quantitative index indicating the degree of the land desertification and evaluating soil deterioration.
