The contents of 23 elements(K, Na, Ca, Mg, Cu, etc.) in the different parts of Phragmites australis (root, stem, leaves, flower) from 7 sampling sites in Lhalu wetland were detected and the distribution characteristics were analyzed. Results showed the element content, transfer and enrichment abilities were quite different when the same element at different parts of Phragmites australis or different elements at the same part. The average mass concentration of the elements ranged from 0.055 mg/kg(Tl) to 2.20×104 mg/kg(Na), the distribution of most elements were sorted from largest to smallest as root>flower>leaf>stem. Phragmites australis had the strongest transfer ability of Ca, while the weakest of Fe. It had the greatest enrichment ability of Fe, especially in roots the enrichment coefficient was 5.06 million times. |
