基于RS/GIS的玛纳斯河流域土壤空间分布的分形与分维

open access: yes, 2010
分形理论在描述不规则几何图形方面的优越性十分显著。基于分形理论,对玛纳斯河流域土壤空间分布的分形性质进行了定量研究,在建立了玛纳斯河流域各土壤类型斑块周长-面积定量关系的基础上,进一步计算出各土壤类型在空间分布上的分维数与稳定性指数,得出以下结论:玛纳斯河流域各土壤类型斑块的周长-面积双对数关系显著,即玛纳斯河流域土壤空间分形结构客观存在。各土壤类型图斑的分维数存在差异,分维数最大的是草甸盐土,为1.7091,最小的是灌耕石灰性草甸土,为1.0524,分维数空间分布的总体趋势是由南向北逐渐变小 ...
