| Abstract: | By analysing regional distribution for soil background volues in nine agricutural natural areas of China, the results are that: elements contented in soils of subtropical zone are higher than that in warm-temperature zone; elements contented in soils are regular progressively increasing from north to south in Shanaxi province; geographic distribution is not uniform in nine areas. |
