摘　　要：为指导炎热天气下骑行者健康出行,以福州市西三环快速路沿侧慢行道为试验靶区,构建基于微型传感器的骑行测量平台,采集骑行者心率(HR)以及骑行路线上PM_(2.5)、PM_(10)和黑碳(BC)等大气颗粒物的高分辨率样本,统计解析骑行者HR变化特征及原因。结果表明:骑行者平均HR呈现小区侧大于沿江侧,与所有颗粒物均表现出较强的长期持续性关联特征;柴油车数量、气温、大气压强分别对全路段、沿江侧和小区侧慢行道的骑行者HR变化有较大解释权重,但骑行者HR也因路侧环境、地形等条件的差异而不同;PM_(2.5)和BC对骑行者HR的影响具有即时效应,PM_(10)的影响存在滞后性。因此,分路段差异化管控机动车,尤其严控排放对骑行者有即时影响污染物的机动车,并引导选择路侧通透、绿化覆盖率高的路线出行,能够提升骑行者出行品质。To guide healthy travel for cyclists in hot weather,a cycling measurement platform using micro-sensors was developed to collect high-resolution data on cyclists'heart rates,as well as atmospheric particulate matter(i.e.,PM_(2.5),PM_(10),and BC(Black Carbon)on the non-motorized lanes of the Western Third-Ring Expressway in Fuzhou.Statistical analyses were conducted to characterize and interpret variations in cyclists'heart rates.Results indicate that cyclists'average heart rates near residential zones are higher than that of riverside segments,showing strong and sustained associations with all measured particulates.The number of diesel vehicles,ambient temperature,and atmospheric pressure are found to significantly influence the heart rate changes across sections of the entire route,riverside,and residential sections,respectively.Cyclists'heart rates also fluctuate due to varying environmental and topographical conditions along the route.Immediate effects of PM_(2.5)and BC on heart rate are observed,while PM_(10)effects are delayed.Therefore,implementing road-segment-specific control measures for motor vehicles,particularly strict regulation of those emitting pollutants with immediate effects on cyclists,and guiding the selection of routes with better roadside ventilation and higher greenery coverage,can effectively enhance the travel quality for cyclists.
