摘    要:应用分形理论分析了英罗港红树林土壤粒径分布的分形特征。结果表明,红树林土壤的分形维数为2.6837-2.8834,不同质地土壤的分形维数呈现砂壤土<轻壤土<中壤土<重壤土<轻粘土的规律,外滩红树林土壤的分形维数低于中滩和内滩。土壤分形维数与其盐分和有机质含量呈显著正相关。群落类型、土壤质地、滩位、含盐量、有机质含量等是影响英罗港红树林土壤分形维数的主要因子。

关 键 词:红树林  土壤  粒径分布  分形维数

Abstract:Based on fractal theory, the fractal characteristics of particle-size distributions of mangrove soils in Yingluo Bay (21 degrees 28'N, 109 degrees 43'E) were studied. The results show that the fractal dimensions of the soils ranged from 2.6837 to 2.8834, and decreased in the order of sand loam < light loam < medium loam < heavy loam < light clay. The fractal dimensions of the soils on exterior beach were lower than those on middle and inner beaches. There was a significant positive linear relationship between fractal dimension and soil salinity and organic matter content. The major factors that influenced the fractal dimensions of the soils were community type, soil texture, beach position, soil salinity, and soil organic matter content.
Keywords:Mangroves  Soil  Particle size distribution  Fractal dimension
