| 摘要: |
| 为了解贵州省土壤-刺梨系统重金属污染现状，更好的保障刺梨品质及当地刺梨产业的持续发展，本文对贵州省土壤-刺梨系统中5种重金属（Pb、Cd、Cr、As、Hg）在不同地区、不同土壤类型下的含量分布情况进行文献分析，并以有关标准对不同地区、不同土壤类型中重金属污染情况进行评价。分析发现不同地区、不同土壤类型下的刺梨果和土壤中各重金属含量分布情况存在差异，贵州省刺梨种植地土壤中Cr含量极显著高于其他重金属，刺梨果中Pb、Cr含量极显著高于其他重金属，刺梨果对Cd的富集显著高于其他重金属。遵义市、盘州市土壤重金属污染及毕节市刺梨果重金属污染相较其他地区较为严重，黄壤、红棕壤中重金属污染及沙壤中刺梨果重金属污染较为严重。相关性分析，发现土壤中重金属元素之间的相关性不仅限于单一元素，还体现在多元素间的交互作用。研究结果可为后续研究土壤-刺梨重金属污染防治提供一定的参考。 |

| Abstract: |
| The content distribution of five heavy metals (Pb, Cd, Cr, As, and Hg) in the soil- Rosa roxburghii Tratt system in Guizhou Province was examined in various regions and soil types in order to better guarantee the quality of the Rosa roxburghii Tratt and the sustainable growth of the local Rosa roxburghii Tratt industry. In accordance with pertinent criteria, the level of heavy metal pollution in various soil types and geographical areas was assessed. The investigation revealed that different soil types and geographical locations had varying concentrations of heavy metals in Roxburgh pear fruit and soil. Pb and Cr content in Rosa roxburghii Tratt fruit were significantly higher than those of other heavy metals, and the enrichment of Cd in Rosa roxburghii Tratt fruit was significantly higher than that of other heavy metals. The content of Cr was also significantly higher than that of other heavy metals in the Guizhou province's Rosa roxburghii Tratt planting field.The contamination of the soil in Zunyi City and Panzhou City with heavy metals, the contamination of the Rosa roxburghii Tratt in Bijie City, the contamination of the yellow and red brown soil, and the contamination of the Rosa roxburghii Tratt in sandy soil are all more severe than in other locations. The correlation between the heavy metal components in soil is not restricted to a single element; rather, it is reflected in the interactions between several elements, according to correlation analysis. The findings of this study can serve as a guide for future investigations into the prevention and management of heavy metal contamination in soil from Rosa roxburghii Tratt. |
