夏尔希里地区土壤重金属含量特征及空间变异分析① 钟巧 王勇辉 焦黎* (新疆师范大学 地理科学与旅游学院 乌鲁木齐830054) 摘要：本文以夏尔希里地区为研究区，对土壤样品中Co、Cr、Cu、Mn、Ni含量为：Mn＞Cr＞Cu＞Ni＞CoCo与Cu、MnCr与Cu、NiCr、Mn、Cu、NiCo和Mn属于轻污染，Cr处于警戒线，属于尚清洁状态。 The Characteristics and Spatial Variability Analysis of Soil Heavy Metals in Xiaerxili Area ZHONG Qiao，WANG Yonghui， （College of geography and tourism，Xinjiang Normal University，Urumq 830054，China) Abstract: Quality of the soil are closely linked with the developments of urbanization and industrialization. In this article, analysis structural characteristics and spatial distributions of five heavy metals (Co, Cr, Cu,Mn and Ni) in the soil in Xiaerxili, and the study area of soil heavy metals pollution condition and characteristics were analyzed by means of single factor index, Nemerow multi factor index and Kriging interpolation method. Research area 5 kinds of heavy metals (Co、Cr、Cu、Mn、Ni) content laws: Mn＞Cr＞Cu＞Ni＞Co, the heavy metals and organic matter belongs to the medium in variability; The results of correlation analysis show that the significantly correlations were found between Co and Cu, Mn, and the correlation coefficient are -0.624 and 0.494, the significantly positive correlations between Cr and Cu, Ni, and the correlation coefficient are 0.541 基金项目：新疆师范大学地理学博士点支撑学科开放课题基金项目（XJNU—DL—201504）和国家自然科学基金共同资助。 * 通讯jiaolixjsd@） 作者简介：钟巧（1991—），女，新疆克拉玛依人，硕士研究生，主要从事干旱区景观生态方面的研究，E-mail:869740826@ and 0.684; Then organic matter and Cr、Mn、Cu、Ni show a positive correlation, but the correlation coefficient is small; The spatial distribution of the heavy metal contents characteristics of overall performance for oasis area＞desert area＞mountain area; The results of assessment of heavy metals pollution Co and Mn belong to light pollution , Cr and Ni are still clean but at the cordon level. These conclusion can provide scientific reference for related research in other areas. Keywords: Xiaerxili area; soil heavy metal; correlation analysis; analysis of pollution index; spatial variab
