The discussion of soil elements of the vertical distribution characteristics at scallions origin Zhangqiu

摘要

The important content of ecological geochemical in Zhangqiu area is soil elements of source and origin. The vertical distribution characteristics about soil elements reflect the content difference between surface and deep soil and provide the important basis for the genetic srudy of elements. This paper used the survey results of the local ecological geochemical, systematically summarizes the element content changes in the vertical profile, then explore the soil element migration regularity and source in this area. The research shows that the relationship is closed between element content and into soil cane in Zhangqiu area. But because of the farming and pollution, S,Se, Hg, N, P element are significant effects under supergene geochemistry activation.
