摘要: 以二道坊河沉积物为研究对象,采用相关与回归分析综合地研究了14种元素在沉积物中的富集特征.结果表明:地球化学性质相近的元素,它们在沉积物中的相关系数大多达到了显著或极显著的水平;通过因子分析,求出了4个主因子,它们代表沉积物中14种元素测定信息的85%,以第一、二主因子对应的特征向量为X、Y轴将14个元素分成了3类;建立了大部分元素与沉积物性质之间的多元回归方程.

Abstract: This paper dealt with the accumulation characteristics of 14 elements in the sediments of Erdaofang River. Correlation and regression analysis showed that the correlation coefficients of elements with similar geochemical properties in the sediments attained to a very significant or significant level. Based on factor analysis, four principal factors which represented 85% of measurement information of 14 elements were selected. With corresponding eigenvectors of first and second principal factors as ax is X and Y,the 14 elements were divided into three types. Multi regression models of most elements and sediment properties were established.
