| 摘 要： | 对乌梁素海表层沉积物营养盐与重金属的分布情况进行研究,应用SPSS统计分析软件对乌梁素海表层沉积物重金属与营养元素进行相关分析和因子分析,并对重金属元素进行聚类分析。营养元素与重金属间的相关分析表明：重金属元素Cu、Cr、Pb和Cd相互间具有极显著的正相关性;有机质与As和Hg呈极显著的正相关;总氮与Hg呈极显著相关,与As呈显著相关,而与Pb呈极显著负相关,与Cd呈显著负相关;总磷与As呈显著负相关。重金属元素间的R-型聚类分析结果将本论文研究的9种金属元素分为3类。采用主成分分析法对乌梁素海表层沉积物重金属与营养元素进行因子分析,得到4个因子,并进一步分析讨论了各主成分的科学内涵。
