春季福建柏林内、林缘与市区的舒适度对比研究

Comparative Study of Human Comfort Level in Fukien Cypress Forest,Forest Margin and City Center in Spring

用陆鼎煌提出的“综合舒适度指数（S）”表征人体舒适度这一生物气象指标，比较了春季福建柏林内外与市区小气候的差异，结果表明：福建柏林缘与市区相比降温幅度为0．6～3．5℃；福建柏林内与市区相比降温幅度为1．3～4．2℃。在增湿率方面，福建柏林缘与市区相比增湿幅度为5．28％～29．27％；福建柏林内与市区相比增湿幅度为7．7％。33．7％。在降低风速方面，林缘与市区相比平均风速降低了0．05m／s；林内与市区相比平均风速降低了0．74m／s。综合各下垫面人体感觉舒适的时间分别为福建柏林内（8h）：福建柏林缘（8h）〉市区（4h）。

The comprehensive comfort index（S） by Lu Dinghuang was used to as a weather index for the comfortable degree of human body to compare the urban microclimate differences with inside and outside of Fukien cypress （Fokienia hodginsii） in spring. Results showed that the temperature at the edge of Fukien cypress was 0.6 to 3.5℃ lower than the city center. The temperature in Fukien cypress was 1.3℃ to 4.2℃ lower than the city center. The humidification rate along the edge of Fukien cypress was 5.28% to 29.27% higher than the city center. The humidification rate in Fukien cypress was 7.7% to 33.7% higher than the city center. Compared with and city center, the average wind speed along the edge of the Fukien cypress reduced by 0.05 m/s and the average wind speed in Fukien cypress reduced by 0.74 m/s. Considering all the indexes, the time when human feel comfortable in Fukien cypress was 8 h, which is the same as at the forest margin, but longer than in the city center （4 h）.
