以在贵州省遵义市习水县寨坝镇采集的42个土壤样品为例,运用分形维数模型分析渝贵地区低中山的土壤分形维数(D)特征及其与土地利用方式、海拔高度、土壤性质的关系,结果表明:研究区的D值介于2.565~2.856之间,均值为2.699,总体变异性较弱,土壤质地为中壤土、重壤土,重壤土D值大于中壤土.土壤分形维数主要由粘粒含量决定(R=0.963),其次与粉粒含量呈显著负相关(R=-0.537),与砂粒含量相关性不明显(R=0.157).不同土地利用类型的D值从大到小依次为草地、旱地、林地、水田.D值和土壤性质中TP质量分数呈显著的正相关关系,但与土壤的其他性质相关性不显著.
Taking 42 soil samples collected in Zhaba Town, Xishui County, Zunyi City, Guizhou Province as an example, the fractal dimension model was used to analyze the characteristics of soil fractal dimension (D) and its relationship with land use patterns, altitude The results showed that the D value of the study area ranged from 2.565 to 2.856 with a mean of 2.699, and the overall variability was weak. The soil texture was medium loam soil, heavy loam soil and heavy loam soil with D value greater than that of medium loam soil. The fractal dimension was mainly determined by the clay content (R = 0.963), followed by a significant negative correlation with the silt content (R = -0.537), but not with the sand content (R = 0.157) The values of descending order were grassland, dry land, forest land and paddy field.The values of D were positively correlated with the TP content of soil, but not significant with other soil properties.
