【摘要】：2017年4月,中国共产党中央委员会和国务院决定在河北设立雄安新区,以推进京津冀协同发展,要将雄安新区打造为环境优美的生态城市.通过分析雄安新区2016年5月24日至2017年4月30日的空气质量数据和气象数据,对该地区的大气污染现状进行了研究,并揭示其与气象条件的关系,旨在为雄安新区的合理规划提供科学依据.研究发现雄安新区的主要大气污染物为PM_(2.5)和PM_(10),其重污染过程主要出现在秋、冬两季,污染程度与相对湿度呈正相关,与风速和温度呈负相关.尽管雄安新区目前的开发程度较低,但受本地排放和周边污染物输送的共同影响,大气污染问题不容忽视.在雄安新区的规划和建设过程中,需要考虑周边地区的协调发展,共同治理大气环境.
[Abstract]:In April 2017, the Central Committee of the Communist Party of China and the State Council decided to establish a new Xiong'an District in Hebei Province to promote the coordinated development of Beijing, Tianjin and Hebei. In order to make Xiong'an New area a beautiful ecological city, the air quality data and meteorological data from May 24th 2016 to April 30th 2017 in Xiong'an New area were analyzed. The present situation of air pollution in this area is studied, and the relationship between air pollution and meteorological conditions is revealed. In order to provide scientific basis for rational planning of Xiong'an New area, it is found that the main air pollutants in Xiong'an New area are PMSP 2.5) and PMSP 10. The heavy pollution process mainly occurs in autumn and winter. The pollution level was positively correlated with relative humidity and negatively correlated with wind speed and temperature. Although the development of Xiong'an New area was low at present, it was affected by local emissions and the transport of pollutants around it. The problem of air pollution can not be ignored. In the planning and construction of Xiong'an New area, it is necessary to consider the coordinated development of the surrounding areas and jointly control the atmospheric environment.
