青岛地区硫传输通量的估算

Calculation of sulphur transmission flux in Qingdao district.

利用三维欧拉模式，估算外地源和本地源对青岛地区硫沉降的贡献，同时估算硫的去除，估算的方法是根据当地的风速、风向，模拟计算各种含硫化合物（包括ＳＯ２、硫酸盐及ＤＭＳ）在青岛地区的各方向上输出或输入青岛地区的量、当地源排放的量以及硫化物的干、湿沉降量。通过估算可以得出，青岛地区硫来源中本地源与外来源相当，硫的去除主要是往外输出，占全部硫来源的８０％以上。

狪n this paper the three-dimensional Eulerian model is used to calculate the contribution of local and outside sources to sulphur deposition and S removal in Qingdao district. The calculation method involves calculating the input and output volume of S compound (including SO 2, sulphate and DMS) in every direction based on the wind speed and wind direction, the emission from local sources and the dry and wet deposit ion amounts of S compounds.This study finds that local and outside sources are well matched in the contribution to the sulphur deposition in Qingdao district and that the transmission outward is the main removal of sulphur, which accounts for 80% of the total sulphur source.
