摘　　要：为评估浙江省一次细颗粒物(PM_(2.5))重污染过程的区域协同减排效果,利用本地化的WRF-CMAQ模型对2017年12月29日至2018年1月2日的PM_(2.5)污染过程进行了模拟。结果显示:(1)城市单独减排时,浙江省11个地市仅宁波市减排效果较好,其他地市减排效果都不理想,需要开展区域协同减排。(2)区域协同减排时,全省特别是污染较重的核心地市减排效果明显提升。(3)各地市减排效果与污染过程的气象条件、地理位置、产业分布有密切关系,开展重污染过程区域协同减排应根据实际情况进行分析,使减排方案具有针对性和可行性。In order to evaluate the effect of regional synergy reduction plans in Zhejiang Province during a PM_(2.5)severe pollution episode,a localized WRF-CMAQ model was used to simulate PM_(2.5)from December 29th,2017 to January 2nd,2018.Results showed that:(1)when each city reduced emissions separately,only Ningbo had a good emission reduction effect,but the other 10 cities had little effect.Therefore,it was necessary to carry out regional synergy reduction plans.(2)By adopting regional synergy reduction plans,the reduction effect of Zhejiang Province,espcially the core prefecture-level cities with severe pollution,increased significantly.(3)The emission reduction effect of each city was closely related to the meteorological condition,geographical location and industrial distribution.When carrying out regional synergy reduction in severe air pollution episode,the regional synergy reduction plans should be analyzed according to the actual situation to make it more targeted and feasible.
