基于PM2.5浓度逐时数据和太原市迎泽公园内锻炼群体锻炼习惯问卷,掌握PM2.5浓度各季节变化规律,探究PM2.5污染对公园日常锻炼居民潜在健康风险,从出行决策的角度为锻炼群体锻炼时间及锻炼方式提出建议.结果表明:1)PM2.5浓度整体呈现“W”型变化,各季节含量:冬季>秋季>春季>夏季.2)2019年太原市空气污染呈现出夏轻冬重的情况,非采暖期空气质量明显好于采暖期.3)居民外出锻炼时间除夏季上午为7～8时人数最多,其余季节均为上午8～9时,下午19～20时人数最多.群体的锻炼方式主要以中等强度运动为主.4)通过将PM2.5逐时浓度季节变化特征与各时段外出锻炼人数特征进行相关性分析得出,春季和夏季PM2.5浓度与外出锻炼人数不具有相关性,秋季和冬季存在显著负相关关系.
Abstract：Based on the time-by-time data of PM2.5concentration and the questionnaire of exercise habits of exercise groups in Yingze Park of Taiyuan City,we mastered the change regulations of PM2.5concentration in all seasons,explored the potential health risks of PM2.5pollution to the residents of the park for daily exercise,and made suggestions for the exercise group's exercise time and exercise mode from the perspective of travel decision-making. The results show that:1)PM2.5concentration overall shows “W” type changes,the content of each season:winter>fall>spring>summer. 2)In 2019,air pollution in Taiyuan City shows a light summer and heavy winter,and the air quality in Taiyuan City in the non-heating period is significantly better than that in the heating period.3)Residents' workout times are the highest except for the morning in summer,when the number of people is 7～8 a.m.8～9 a.m.and 19～20 p.m.in the rest of the seasons.The exercise mode of the group mainly focuses on moderate-intensity exercise.4)Correlation analysis between seasonal changes in PM2.5concentration and the number of people who go out for exercise in each time period shows that there is no correlation between PM2.5concentration and the number of people who go out for exercise in spring and summer,and there is a significant negative correlation between PM2.5concentration and the number of people who go out for exercise in fall and winter.
