摘　　要：为探讨干旱半干旱城市公园绿地夏季连续测量下植被的环境效应及相关因子的影响,于2020年7月—8月天气晴朗且人为干扰因素较小的10 d,选取呼和浩特市敕勒川公园落叶阔叶疏林、落叶阔叶密林、针阔混交密林、针阔混交疏林等4种不同配置结构的植物群落及对照点为监测点,分析人体舒适度、空气颗粒物、负离子、噪声等日变化规律及影响因素。结果表明:落叶阔叶密林日平均人体舒适度指数最小,人体舒适度感受最好;针阔混交密林颗粒物日平均浓度最低,空气质量最好;落叶阔叶密林负离子浓度最高,可达1030.37个/cm^(3);针阔混交密林的噪音最低,可达55.30 dB;综合各项指标,落叶阔叶密林的环境效应最好,人们在选择户外休闲锻炼,建议选择落叶阔叶密林附近的区域。In order to explore the environmental effects of vegetation and related influencing factors under continuous measurement in urban park green space in summer,10 days with sunny weather and less human disturbance in July and August 2020 were selected,four plant communities(i.e.,deciduous broad-leaved dense forest,deciduous broad-leaved sparse forest,evergreen coniferous and deciduous broad-leaved mixed forest,evergreen coniferous and deciduous broad-leaved mixed forest,evergreen coniferous and decid-uous broad-leaved mixed forest)with different configuration structures in the Chilechuan Park in Hohhot,and the control point on the edge of the road outside the park were monitored.The daily variation of human comfort,air particulate matter,negative ions,noise,and the correlation of related influencing factors were analyzed.The results showed that the human comfort index of the decidu-ous broad-leaved forest was the lowest among the five monitoring sites,making the human body feeling best.The daily average concen-tration of the particulate matter in the deciduous broad-leaved and evergreen coniferous mixed forest was the lowest,and the air quali-ty was the best.The negative ion concentration in the deciduous broad-leaved mixed forest was the highest,reaching 1030.37 ions/cm^(3).The deciduous broad-leaved forest and evergreen coniferous forest had the lowest noise concentration with the value of 55.30 dB.Considering the environmental effects of the five monitoring sites,the deciduous broad-leaved forest had the best environmental effect.People could choose the area near the deciduous broad-leaved forest when they choose outdoor leisure exercise.
