福州冬季兰花植物园舒适度对比

Comparasion on Comfortable Level in Orchid Botanic Gardens of Fuzhou in Winter

选择2月中旬晴朗天气,通过对冬季福州市3个兰花专类园（分别位于远郊、近郊、市中心）6个监测点的温度、湿度、风速、热力指数、湿球指数、露点温度等数据的采集,采用综合舒适度指数模型进行数据分析. 研究了3个兰花植物园温度、湿度、风速及舒适度的日变化规律以及不同区位条件下的对比变化,并对兰花植物园与福州市背景气象数据进行相关性分析. 结果表明,各兰花专类园的温度、湿度呈＆quot;U＆quot;字型变化,温度在13：00～15：00时较高,7：00时最低;湿度在7：00时最高,13：00左右最低;风速呈不规则式变化;综合各下垫面,人体感觉舒适的时间呈U字型变化;冬季3个点皆为林缘舒适度高于园内;3个兰花植物园的舒适度对比为远郊〈近郊〈市区;与市区背景气象数据相比得出,3个兰花植物园的相对湿度大于市区,平均温度及平均风速明显小于市区.

Selecting a sunny day in mid-February, through the collection of data such as temperature, humidity, wind speed, thermal index, web bulb index and dew point temperature on 6 monitoring point in 3 orchid specialized gardens （being respectively located in outer suburbs, suburbs and the downtown） in Fuzhou City in winter, ＆quot;integrated comfort algorithm index＆quot; model was adopted to carry on data analysis. The daily change rule of temperature, humidity, wind speed and comfortable level in 3 orchid botanic gardens and comparative change were studied, and correlation analysis between background meteorological data of orchid botanic garden and Fuzhou City. Results showed that temperature and humidity in every orchid specialized garden presented font variation of U, the temperature during the time from 13：00 to 15：00 was higher, and the temperature was the lowest at 7：00; The humidity was the highest at 7：00, and the humidity was the lowest at 13：00; Wind speed presented irregular style change. The integration of time for which human body feeled comfortable on underlying surface, which presented font variation of U; Each comfortable level on forest edge on 3 points was higher than that of the garden inside; Each comfortable level in 3 orchid botanic gardens respectively located in outer suburbs, suburbs and the downtown was contrasted to show that outer suburbs〈suburbs〈the downtown; Compared with background meteorological data in the downtown, it could be reached that relative humidity in 3 orchid botanic gardens was higher than that of the downtown, and average temperature and wind speed was obviously lower than that in the downtown.
