| 摘 要： | 通过对杭州城市灰尘迁移循环模式和不同粒径质量分布特征分析，表明灰尘的来源和搬运方式有关，灰尘的搬运有悬移、跃移和蠕移，其中粒径小于0．1mm的灰尘主要来自异地高空运输，占30％，周边地区的中细尘源占40％，城市内部局地粗尘源占30％。

| Abstract: | Based on the analysis of the dust moving and cycle mode and the distributing character of different size of the dust of Hangzhou city, it indicates that the source of the dust is related to the moving mode which includes float moving, jumping moving and squirming moving. The dust with diameter less than 0.1 rnm mainly comes from other place from upper air which occupies 30 % of all the city dust. The middle size around is about 40% and thick dust in the city is 30%. |
