Abstract: Based on fractal theory, the fractal characteristics of particlesize distributions of mangrove soils in Yingluo Bay (21°28′N,109°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.
