摘  要:
以日照市茶树种植区为研究对象,对其表层土壤重金属元素的空间分布特征进行分析,利用内梅罗综合指数法评价其环境质量状况,并将评价结果利用ARC/MAP地统计模块中的克里金插值法插值处理。结果表明,日照市茶树种植区重金属元素分布较为均匀,仅Cd,Hg的空间变异性相对较大;根据单因子污染指数评价结果,大部分地区环境质量较好,仅在局部地区存在Cd,Ni污染;根据内梅罗综合污染指数空间分布,大部分地区土壤属于Ⅰ级,少部分属于Ⅱ级和Ⅲ级,整个区域未出现Ⅳ级和Ⅴ级土壤。

摘  要:
Geostatistics method was used to analyze the spatial distribution patterns of heavy metal elements,and Nemerow integrated index method was used to assess environmental qualities regarding heavy metals in tea-planting areas of Rizhao City.The results of assessment were then displayed with Kriging interpolation in ArcMap.The results show that the distributions of all the heavy metals except Cd and Pb were comparatively uniform.The single factor pollution index indicate that the majority of the research areas was clean except that Cd and Ni pollution existed in some parts of the area.The spatial distribution of Nemerow integrated pollution index show that 88.41% of the research areas soil was classified as level Ⅰ,and 6.44% as level Ⅱ,and 5.14% as level Ⅲ,while no area as Ⅳ and level Ⅴ.
