Changing Characteristics of Human Comfort in a Typical Urban Forest in Yinchuan
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.
