园林绿地秋季温湿度与细颗粒物(PM2.5)浓度的关系研究——以北京玉渊潭公园为例

摘要

近年来,空气质量越来越成为社会所关注的主要环境问题之一,尤其是以PM2.5为代表的空气颗粒物,对居民生活产生了巨大的影响.园林绿地是城市重要的组成部分,具有降低空气污染物等生态功能.以北京玉渊潭公园为研究地点,采用多点同步连续监测的方式,对公园内不同区域的温、湿度及细颗粒物(PM2.5)浓度进行监测.通过一个完整秋季的数据,分析园林绿地中温、湿度和PM2.5浓度在秋季的变化情况,温、湿度和PM2.5浓度之间的相关性,以及不同站点间温、湿度与PM2.5浓度之间的关系.%Recently,air quality is becoming one of the environmental issues which are most concerned by the public,especially the fine particular matters (PM2.5),which had huge influence on residents' daily lives.Green spaces are important components of a city,and have ecological functions to reduce air pollutants.This paper concurrently monitored temperature,humidity and fine particles at different places in Yuyuantan Park,Beijing.By the analysis of the data in autumn 2017,some conclusions were drawn on the change of temperature,humidity and fine particles during autumn,the correlation between temperature,humidity and fine particles,and the difference average temperature,humidity and fine particles among different places in the park.
