摘要
以广东省淇澳岛红树林林内和林外无林地作为研究对象,评估红树林温湿小气候环境对人体的舒适度。每天从8:00-18:00,每隔10 min 1次,同时测定红树林内和林外无林地的温度和相对湿度,每月连续测定3 d,持续测定1 a。对两站点的气候因子的日变化和年变化进行对比和分析。结果表明:在测定的时间段内,红树林林内的气温一直低于林外无林地,相对湿度则高于林外无林地,红树林日降温幅度在0.6-2.4℃,平均降温1.3℃,平均降温率3.92%;日增湿幅度4.0%-20.7%,平均增湿8.0%,平均增湿率12.0%;两地气温、相对湿度的日最大差值出现在14:00左右,年最大差值出现在8月份,通过对温湿度指数的计算,红树林小气候对人体舒适度有一定的调节作用。
The open spaces within and around mangrove in Qi＇ao Island of Zhuhai, Guangdong Province were investigated to estimate the effects of mangrove microclimate such as temperature and humidity on human comfort. From 8：00 a.m. to 18：00 p. m. everyday, the temperature and relative humidity in clearings within and around mangrove were measured simultaneously every 10 minutes, continuously 3 days per month, and the measurement lasted for one year. Comparison of the daily and annual variation of climate factors between two sites was conducted. During the test, the temperature within the mangrove was lower than that around it, but the relative humidity was higher. In the mangrove, the daily temperature decreasing was in the range from 0.6 ℃ to 2.4 ℃ with the mean value of 1.3 ℃ in the average percentage of 3.92%, while the daily humidity increasing was in the range from 4.0% to 20.7% with the mean value of 8.0% in the average percentage of 12.0%. Between two sites, the daily maximum difference values of temperature and relative humidity occurred at 14 ： 00 p. m. , while the annual maximum difference values occurred in August. According to calculation of temperature and humidity indices, the effects of mangrove microclimate on human comfort were proved.
