Abstract Characteristics of toxic elements and nutritive elements for plants in Changshou Wushan sector along the middle reach of the Yangtze River were systematically studied in this paper. Cd and Hg are the most important toxic elements. Compared with the average values of the whole country, the nutritive element abundances have the following characteristics: Corg is over two times higher than and N, B, TFe2O3, Zn and K2O are over one time higher than their respective average values in the earth. The major famous quality and special products are mustard tuber, navel orange of Fengjie and subtropical fruits.
