The Analytic Methods of Mineralization Anomaly on Soil Radon Concentrations Based on Fractal Theory：A Case Study of Jinshiling Destrict of Chenzhou,Hunan
土壤氡浓度分布具有双分形特征,其分维值分别为 D 1=0.079 4和 D 2=1.465 4,分形临界值为2 167.7 Bq/m 3.低于临界值的分形其分维值 D 1很小,代表了区域背景分布,其背景值为1 088.16 Bq/m 3.高于临界值的分形其分维值 D 2显著增大,反映该区发生了较强的成矿作用的叠加.分形临界值可以作为异常下限值.金狮岭地区土壤氡浓度异常区分布范围较大,表明具有较好的成矿远景.
摘要(英文)：
The distribution of radon concentration in soil contains the characteristics of double fractal,the fractal dimension is D 1=0.079 4 and D 2=1.465 4 respectively,and the fractal threshold is 2 167.7 Bq/m 3.The fractal dimension value of D 1 is very small, which represents the region background distribution,and its background value is 1 088.16 Bq/m 3.The fractal dimension value of D 2 is higher than the critical value,and the strong mineralization superposition occurs in the reaction zone.The fractal critical value can be used as the lower limit value.The distribution of radon concentration anom...
