珠江三角洲城市间空气污染的相互影响

Interaction of urban air pollution among cities in Zhujiang Delta.

以2002年源排放清单、气象资料和空气质量观测资料为基础,利用CALPUFF模拟系统,通过数值模拟及对排放源现状分析,揭示了珠江三角洲内城市之间污染物相互输送的特点和规律,分析了不同城市空气污染影响因素的差异,定量给出了珠江三角洲城市间空气污染的相互影响和相互贡献.结果表明,珠江三角洲城市间污染相互作用显著,其中广州是最典型的与周边发生显著相互作用的城市之一.

Based on the year 2002 pollution emission inventory, meteorological data and atmospheric pollutants monitoring data. Utilizing CALPUFF simulation system, through numerical value simulation and analysis of current status of emission sources, the characteristics and the rule of the pollutants transport among cities in Zhujiang delta were demonstrated; the difference of urban air pollution influence factors in different cities were analyzed, and the interaction and mutual contribution of urban air pollution among these cities were quantitatively described. The interactions of urban air pollution influence factors among cities in Zhujiang delta are significant. Guangzhou is one of the most typical cities which have dramatic interactions with the circumjacent cities.
