摘要
以华北地区重工业城市唐山作为研究对象,探讨工业型城市大气降尘元素组成及时空分布特征.表明唐山市区降尘中主要污染元素为Fe、Ca、Sr等;元素浓度呈冬春季偏高,夏秋季偏低的趋势;空间分布充分体现了与污染源地域分布的一致性.
This study discusses the element composition of dustfall and the temporal and spatial distribution of content in the industrial cities through studying the heavy industrial city of Tangshan in Huabei District. The results indicated that the main exceeding normal elements are Sr、Fe、Ca etc. in 37 kinds of elements of dustfall; Some elements contents reflected more variations tendency in spring and winter and less in summer and autumn; The planar distribution tendency was identical with the space distribution of the pollution sources.
