英文摘要	Forty-four soils representing the eight types of soils in China were sampled, and their total rare earths and La, Ce, Nd, Sm and Y contents were measured by spectrophotometric and ICP-AES methods, averaging 264, 43.7, 86.2, 35.8, 8.38, and 21.8 mu g.g(-1), respectively. Rare earth elements were accumulated and leached to a different extent in the various soil-forming processes, but REE contents in the soils showed no zonal variation. The available rare earth contents in the sixty-one soil samples, averaging 24.9 mu g.g(-1), present a decreasing trend from the South to the Not-thin China. About 17% of the total acid soil samples are lower than 10 mu g.g(-1) in available rare earths, whereas 77% of the total neutral and calcareous soil samples are below the value. Availability of soil REE is primarily affected by pH, Eh(redox potential), and clay contents in the soils.
