Abstract

Soil heavy metal pollution has become a focus of attention in the world. The poplar trees have some characteristics: easiness to plant, quick growth, strong resistance, and large biomass. Therefore, the poplar is taken as the example and this paper studies the enrichment characteristics of different heavy metalspaper. The results are shown that: (1) the enrichment ability of heavy metals by polar is: zinc > copper > cadmium > lead > nickel > chromium. As for different parts, the heavy metal enrichment capability of leaf is the largest. (2) The transfer ability of heavy metals by polar is: copper > cadmium> zinc > lead > nickel > chromium. Among them, the transfer coefficient of chromium by poplar stem is the largest, and leaf has the maximum transfer coefficient on the rest five heavy metals. In summary, the results indicate that zinc, copper and cadmium are the enrichment heavy metals of polar.
