| 摘 要： | 以淮南市表层土壤重金属Pb含量为例,针对其存在趋势与偏态分布的特点,利用指示克里格法研究了土壤Pb含量大于特定阈值的条件概率分布,分析了该地区土壤中Pb含量的空间分布特征。结果表明:研究区表层土壤Pb含量总体不高,但不同部位Pb含量差异较大。指示克里格法适用于原始数据呈非正态分布的土壤属性。该研究结果为该地区土壤环境质量评价和重金属污染防控提供科学依据。

| Abstract: | Considering the skew distribution and trend of heavy mental Pb- content in Huainan soils, indicator method was introducect to study the conditional probability of soil Pb content that exceeds the cutoff. The spatial variability of soil Pb content was analyzed across the study are- a. The results indicated that soil Pb content in Huainan city is not so high, whereas the Pb content varies greatly at various locations. Indicator kriging method is suitable to soil properties with non-normal distribution. The results provide a scientific reference to the quality of environment and prevention of soil heavy mental contamination for Huainan city. |
