以种植红托竹荪的基地土壤中重金属为研究对象,共采集19个基地的土壤样品,利用原子荧光法和原子吸收法测其重金属的含量,对基地土壤中重金属的富集系数和生态危害系数以及生态危害指数进行了分析,采用了瑞典学者LarsHakanson潜在生态危害指数法对基地土壤中重金属的生态危害进行了评价。结果表明:土壤中铬和铅的含量较高,汞的含量较低,其含量的大小顺序为Cr>Pb>As>Cd>Hg;镉对基地土壤生态环境已造成较强或很强的生态危害,砷、铅、铬等重金属未对基地土壤造成生态危害。3、9、13、14和18号基地不适合作红托竹荪种植基地;1、2、7、8、12、15和16号基地符合红托竹荪种植基地要求。
A total of 19 soil samples were collected from the soils of the base of Phyllostachys erythrophylla. The contents of heavy metals in the soils were measured by atomic fluorescence spectrometry and atomic absorption spectrometry, and the enrichment coefficients of heavy metals and ecological hazards The coefficient and the index of ecological risk were analyzed. The ecological risk of heavy metals in base soil was evaluated by the Lars Hakanson potential ecological risk index method of Swedish scholar. The results showed that the content of Cr and Pb in soil was high and the content of Hg was low, the order of content was Cr> Pb> As> Cd> Hg. Cadmium had a strong or strong ecological environment in the base soil Hazard, arsenic, lead, chromium and other heavy metals did not cause ecological harm to the base soil. 3, 9, 13, 14 and 18 base unsuitable for Phyllostachys grandis planting base; 1, 2, 7, 8, 12, 15 and 16 bases in line with the Red Bamboo Shoushen planting base requirements.
