中文摘要:
      贵州遵义松林地区华南下寒武统黑色页岩 Ni-Mo 矿化带土壤质量评价具有重要的科学及实际意义。以松林土壤为研究对象,采用 ICP-MS 方法分析其中23个元素的含量,分析结果显示具有高镉、砷、汞含量特征。运用地质累积指数和潜在生态风险指数分别对土壤镉、砷污染程度和潜在生态风险进行评价,评价结果表明:遵义松林土壤已遭受镉、砷相对较高程度的污染;该区土壤镉、砷具有较高潜在生态风险,值得进一步的土壤污染修复研究,以期为土地资源管护、农业结构的调整和特色山地农业的发展及永久基本农田划定提供科技支撑。
英文摘要:
      Evaluation of soil quality in the mineralized zone of black shale Ni-Mo Lower Cambrian in Zunyi, Guizhou is of great scientific and practical significance. ICP-MS method was used to analyze the content of 23 elements in pine forest soil. The results showed high cadmium, arsenic and mercury content. Geological accumulation index and potential ecological risk index were used to evaluate the soil cadmium and arsenic pollution degree and potential ecological risk respectively. The results showed that the soil of Zunyi pine forest had been polluted by cadmium and arsenic; Soil cadmium and arsenic in this area have high potential ecological risk, so it is worth further study on soil pollution remediation. It provides scientific and technological support for the management and protection of land resources, the adjustment of agricultural structure, the development of characteristic mountain agriculture and the delineation of permanent basic farmland.
