摘　　要：利用电子探针对南昌市降尘颗粒物的形貌特征和成分进行了分析,并探讨了它们的来源。得出南昌市降尘颗粒物的主要组成为矿物颗粒、钙质颗粒以及块状烟尘集合体和燃煤飞灰颗粒。不同功能区的采样点颗粒物的组成有一定差异,表明颗粒物的来源不同。根据颗粒物的来源和分布特点,认为南昌市的城市规划布局不甚合理,尚需进一步改善。Electronic probe is used to analyze the morphology and component of atmospheric dust in Nanchang, and the sources are discussed. The results indicate that the main particles are composed of mineral particles, rich in Ca particles, massive soot aggregate and coal combustion fly ash. The composition of the particles is different in different functional areas. This shows that the sources of the particles are from different part. According to the sources and distribution of the particles, the city planning of Nanchang is unreasonable and it needs to improve.
