中文摘要	选择干旱区典型城市河流乌鲁木齐市水磨河为研究区,结合经典统计学与地统计学相关方法理论,研究了乌鲁木齐市水磨河沿岸土壤重金属含量的分布特征及其污染评价。结果表明:水磨河沿岸土壤重金属含量在土层深度上差异较小;从土地利用方式来看,人为活动明显干扰重金属在沿岸土壤分布中的含量变化,重金属元素间的相关关系在一定程度上反映着几种重金属的同源性与差异性;主成分分析表明, Cu和Zn为水磨河沿岸土壤特征重金属元素,且重金属因子负载图表明Cu和Zn含量存在多因素控制;从空间分布来看,水磨河表层土壤重金属含量分布高值点位置基本相似,主要在河流南端(上游硫磺沟附近)并与河道遇水库、遇支流有关,高值点主要集中在青格达湖、塔桥湾水库、九道湾水库和硫磺沟附近;水磨河沿岸不同土层重金属的单因子污染指数平均值均小于1,整体表现为未污染状态;内梅罗综合污染指数分别为1.26(0-20cm),1.20(20-40cm),1.32(40-60cm),介于1.0
英文摘要	The study area was Shuimo River,a typical urban river in the arid area in Urumqi.Heavy metal contents and distribution characteristics in the riparian soils of the Shuimo River were studied,and heavy metal pollution was evaluated,by combining classical statistics and geo-statistics correlation method.The results showed that the contents of heavy metals differed slightly at different soil depths.From the aspect of land use mode,human activities significantly interfered with the change of heavy metal content in the riparian soils,the correlations between heavy metals reflect the homology and diversity of several heavy metals to some degree.The results of principal component analysis indicated that Cu and Zn were the characteristic heavy metals which were controlled by multiple factors.From the aspect of spatial distribution,the peak value points of the distribution of heavy metals in the surface soil was similar,being mainly at the southern tip of the river.Single factor pollution indices of heavy metals in the riparian soils at different depths were all less than one,indicating that the soil was not polluted.Nemerow integrated pollution index in the riparian soils at different depth was 1.26(0-20cm),1.20(20-40cm)and 1.32(40-60cm),respectively,all with 1.0
