| 摘 要： | 运用分形理论,选取斑块形状指数,在对三工河流域土壤斑块的标度-频度分形关系进行定量分析的基础上,结合土壤斑块面积-周长分维数,讨论了流域内土壤斑块空间分布的复杂性。结果表明:三工河流域内土壤斑块标度-频度分形关系及土壤类型斑块面积-周长分形关系客观存在;流域内土壤类型分维值具有一定差异,其中潮土的分维数最大,硫酸盐草甸盐土最小。复杂性指数与分维数和形状指数之间具有很好的相关性,能较客观地反映土壤类型斑块在空间分布上的复杂性;流域内高山寒漠土的复杂性指数最大,空间分布最复杂(K=2.403),半固定风沙土的复杂性指数最小,空间分布最简单(K=1.259)。 |

| Abstract: | Based on fractal theory and patch shape index, scale/frequency relations of soil patches in Sangong River Basin were quantitatively analyzed. By combining soil patch area/perimeter fractal dimensions and shape index, soil type spatial distribution complexity in Sangong River Basin were discussed. Results show clear scale/frequency relations and area/perimeter relations of the soil patches in Sangong River Basin. Fractal dimensions of the soil types differ substantially in the basin. The highest fractal dimension is in alluvial soils and the lowest in meadow soloncha soils. There is significant correlation between complexity index and fractal dimension or patch shape index. The complexity index largely reflects the spatial distribution complexity of the soils. The most complex spatial distribution is in the alpine desert soils (K=2.403) and the simplest in semi-fixed aeolian soils (K=1.259). |
