中文摘要：

根据湖州市吴兴区采样数据，分析了城市灰尘元素中亲铁元素、亲铜元素、亲石元素和常量元素的含量和累积状况，并探讨这些元素与土壤背景的关系。结果表明，湖州市城市灰尘四类元素含量差异较大，但与土壤背景变化趋势基本一致；同种元素在不同功能区的富集等级基本相同，但同类元素问存在明显的累积差异；各功能区灰尘元素与土壤背景的关联度都较好，关联程度由高到低顺序是科教文，工业区，居民区，旅游区，商业区。提示无论人类活动干扰是否强烈，土壤始终是城市灰尘元素的重要来源。

英文摘要：

According to the date of Wuxing in Huzhou city, the content and accumulation of pro inon, pro copper, lithophile and major elements in urban dust was analysed, and investigated the relationship between these elements and background. The result show that the element of urban dust in Huzhou have quite different, but consistent with the soil background; the same element are in the same grade of enrichment on different urban functional areas, and different elements show significant differences in cumulative. Functional areas have a good correlation with soil background, the degree of association is cultural district, industrial zone, neighborhood, tourist area, business district. Finally, regardless of whether a significant human activity, soil has always been an important source of element in urban dust.
