毛竹林土壤及竹笋重金属含量分析

Analysis of Heavy Metal Contents in Moso Bamboo Forest Soil and Bamboo Shoots

在浙江遂昌县森林食品基地建设区的垵口乡,测定分析了毛竹林土壤及竹笋中的重金属含量。结果表明,垵口乡土壤中铅、铜、镉的含量和竹笋中铅和镉的含量在区域分布上均呈现从北向南逐渐上升的趋势;66个冬笋样品和72个春笋样品中重金属含量不合格率也呈现从北向南逐渐上升的趋势。因此,建议对该乡毛竹林实行分类经营,北部地区可以建设笋竹两用林基地,南部地区建设以生产竹材为主的材用林基地。

The heavy metal contents in Moso bamboo forest soil and bamboo shoots were tested and analyzed at Ankou Towhsnip in Suichang Forest Food Base, Zhejiang. The results showed that Pb, Cu and Cd contents in soil and Pb and Cd contents in bamboo shoots represented a rising trend geographically from the north to the south, and the rate of failure in the test of heavy metal content among 66 winter shoot samples and 72 spring shoot samples also showed an increasing trend from the north to the south. It was suggested that Moso bamboo forest should be managed by classification： bamboo timber and shoot forest could be established in the northern area while bamboo timber forest could be built in the southern area.
