滁州学院南校区不同类型绿地微气候效应分析

Analysis of Microclimate Effect of Different Types of Green Space in South Campus,Chuzhou University

为了探究微气候效应与人体热舒适度,提升校园生活环境质量,以滁州学院南校区不同绿地为研究对象,采用定点测量法对微气候要素进行实测,并在实测点2 m外发放调查问卷。结果显示,空气温度在3.6℃~14.4℃、相对湿度为39.6%~69.4%、风速为0.4~1.5 m·s^(-1)、太阳辐射为6.4~185 w/m^(2)的条件下,3/4的学生对室外热环境有不同的感觉,热舒适接受为72.79%,不可接受为27.21%。人体热舒适度(PET)范围为9.1℃~22℃,PET与温度之间有极强正相关性,系数区间为0.667~0.984;PET与相对湿度有着极强负相关性,系数为0.639~0.955;PET与风速有负相关性,系数为-0.457~-0.524;太阳辐射与PET有正相关性,系数为0.536~0.694。此研究可为校园生活质量改善提供依据,以加强冬季校园热环境建设。

In order to explore microclimate effect and human body thermal comfort degree,and improve the quality of campus living environment,the study takes different greenbelts in South Campus,Chuzhou University as the research objects;adopts fixed point measurement method to make actual measurement on microclimate elements;and does questionnaire 2 m away from actual measurement sites.The results show that 3/4 students have different senses of outdoor thermal environment,thermal comfort acceptance rate is 72.79%,and unacceptance rate is 27.21%.PET scope of human thermal comfort is 9.1℃~22℃.There is strong positive correlation between PET and temperature,and the coefficient is 0.667~0.984.There is strong negative correlation between PET and relative humidity,and the coefficient is 0.639~0.955.There is negative correlation between PET and wind speed,and the coefficient is-0.457~-0.524.There is positive correlation between solar radiation and PET,and the coefficient is 0.536~0.694.The study can provide reference for the improvement of campus living quality,to promote the construction of campus thermal environment in winter.
