根据对长沙市公园土壤的重金属含量测定结果,采用内梅罗综合污染指数对其进行了评价,并运用相关分析、聚类分析进行了统计分析.研究结果表明,岳麓山公园、烈士公园土壤重金属含量较低,月亮岛土壤重金属含量较高.通过内梅罗综合污染指数评价,认为岳麓山公园土壤属于安全级别,未发生重金属污染;烈士公园土壤中Cr、Hg、Cd属轻污染,其余重金属无污染;月亮岛中土壤重金属污染相对严重,其中Zn、Cd属重污染.通过相关分析表明,与pH值呈正相关的为Cr、Zn、Pb、As;聚类分析研究表明,在距离为20分为两大类Cr、Zn;Hg、Cd、Cu、As、Pb、pH.

Based on the analysis of heavy metals in soils of Changsha parks, using the Nemero pollution index, and correlation analysis, cluster analysis for statistical analysis,the content of heavy metals in soils of Changsha parks was evalated. The results show that Yuelushan Park and Lieshi Park of heavy metals in soils low, and Moon island with a high level of heavy metals in soils. Through the Nemero pollution index evaluation that Yuelushan park belongs to the security level of soil, no heavy metal pollution.Cr, Hg, Cd belong to light pollution in soil of Lieshi park, and the others no pollution. Heavy metals pollution in soil of Moon island is relatively serious, in which Zn, Cd is a heavily pollution. Through correlation analysis showed that the pH value and a positive correlation for Cr,Zn,Pb,As.cluster analysis showed that at a distance of 20 is divided into two major categories of Cr,Zn;Hg,Cd,Cu,As,Pb,pH.
