摘要: 研究了被动式SO2采样法在杭州市区使用的可适性,建立了其与空气自动监测数据的回归方程,自动监测值=0.3360×挂片值+47.20,r=0.805;利用被动采样法适用地域范围广、使用周期长的特点,分析了杭州市区空气中的SO2浓度及变化,并使之图形化.结果表明,不同气候条件下SO2的高值中心位置不同,夏季大气扩散条件好,高值中心南移,冬季逆温层厚,高值中心区变大;酸雨的发生强度与发生频率与大气中SO2浓度的季节变化趋势一致.

关键词: SO2, 时空分布, 被动采样, 酸雨, 杭州

Abstract: The feasibility of diffusible sampler for monitoring SO2 in cantonal Hangzhou was studied,and its correlation equation with automatic monitoring was built. The distribution and variation of SO2 concentration in Hangzhou were analyzed and mapped. Position of SO2 concentration centre was changed along with different climate condition. SO2 concentration centre moved towards south in summer with higher diffusion capability of atmosphere and enlarged in winter with thicker inversion layer. Intension and frequency of acid rain were consistent with change tendency of SO2 concentration.

Key words: SO2, Spatial temporal distribution, Passive sampling, Acid rain, Hangzhou
