摘要
城市森林能为人们能提供舒适的场所。以银川市的银川植物园(市郊公园)和花博园(城市公园)为研究对象,监测气温、相对空气湿度、平均风速等气象指标,计算综合舒适度指数,分析不同季节的舒适度指数日变化及舒适时长变化。结果表明:2019年舒适度指数计算得出一天中户外最舒适的时间均为15:00—18:00,最舒适季节是夏季,全天综合舒适度指数都处于很舒适范围内;2021年舒适度指数计算得出一天中户外最舒适的时间与2019年相同,为15:00—18:00,舒适度达到舒适等级的小时数在夏季最多,可见,城市森林建设应增加阔叶树种或乔木灌木配种,增加林分郁闭度,提升林分结构复杂程度,以最大限度发挥城市森林对城市环境调节作用。
Urban forests can provide people with comfortable leisure and recreation places.In this paper,Yinchuan Botanical Garden(a suburban park)and Flower Expo Garden(a city park)in Yinchuan City were used as the study sites to monitor meteorological indicators such as air temperature,relative air humidity,and average wind speed,to calculate the comprehensive comfort index,and to analyze the daily changes of the comfort index and the seasonal changes of the comfort hours in different seasons.The results show that:1)The Comfort Index calculations for 2019 all yielded the most comfortable hours of the day outdoors from 15:00-18:00,with the most comfortable season being summer,and the composite comfort indexes for the entire day were in the very comfortable range.The Comfort Index calculations for 2021 yielded the most comfortable hours of the day outdoors from the same time as in 2019,15:00-18:00,and the number of hours reaching the comfort level is likewise highest in the summer months.Therefore,urban forest construction should increase the planting of broad-leaved tree species or mix tree and shrub species to enhance forest density and structural complexity,thereby maximizing the environmental regulation role of urban forests.
