| ABSTRACT |
| The soils in the South China Sea Islands (SCSI) were divided into three types, namely, phospho-calc soils, skeletisols and coastic solonchaks, which were derived from bio-clastic and strongly calcareous sediments. In comparison with their parent materials, the phospho-calc soils have higher contents of P, Zn, Cu, Ba, and Cd, which tend to increase gradually with time, and lower contents of Mg, Ca, Sr, B, V, Pb, and Mo, which tend to decrease by degrees with time. The above-mentioned constituents in skeletisols and coastic solonchaks are similar to those in their parent materials except for P and Na. The factors affecting element distribution are mainly special bioclimate and parent material, meanwhile, resulting in the remarkable influence on element distribution through soil-forming time. |
