[Objective] The research aimed to study the effects of human activities in Shihezi City on spatial distribution and urban ecology. [Method] The samples farm Shihezi City were collected and analyzed. pH was analyzed by Sartorius PB-10 pH meter.The particle size distribu-tion was analyzed using the Malverns Maateraizer-S.The non-dust fraction (particles ＞0.1mm) was separated by wet-sieving. As,Cu,Cr,Mn,Ni, Pb and Zn were analyzed using XRF. [Result] Compared with background value of soil heavy metal elements in China,the concentration of As, Cr,Cu,Mn,Ni and Zn was higher and the concentration of Pb was lower. [Conclusion]There was notable variation among the enrichment factor of Aa,Cr,Cu,Mn,Ni,Pb and Zn in different area and is was affected by parent material,human activity,industry,and traffic pollution.%[目标]探讨石河子市内人类活动对自然表土度城市生态系统的影响.[方法]利用X光谱仪、酸度计、筛分法与激光粒度仪,测量新疆石河子市表土层样品的重金属元素、pH及＞0.1 m、＜0.001mm的粒径组分.[结果]与我国土壤元素背景值相比,城市表土中As、Cr、Cu、Mn、Ni、Zn等平均浓度较高,Pb相对于我国土壤元素背景值浓度较低.[结论]As、Cr、Cu、Mn、Ni、Pb、Zn等重金属元素的富集因子在各功能区有明显的差异,表明由不同程度、方式的人类活动引起表土重金属元素聚集程度的差异.
