基于分形理论，研究了英罗湾(北纬21°28‘，东经109°43’)红树林土壤粒度分布的分维特征。结果表明，土壤的分维值在2.6837~2.8834之间，由大到小依次为砂壤&轻壤土；中壤土&轻粘土；重壤土&轻粘土。外滩土壤的分维低于中滩和内滩。分维与土壤盐分和有机质含量呈显著的线性正相关。影响土壤分维的主要因素是群落类型、土壤质地、滩涂位置、土壤盐分和土壤有机质含量。
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.
