安庆狮子山公园植物景观空间微气候舒适度评价

Microclimate Comfort Evaluation of Plant Landscape Space in Shizishan Park of Anqing City

为研究不同植物群落空间对人体舒适度的影响,以安庆市狮子山公园为对象实地测量小气候数据,研究了安庆市狮子山公园植物群落的郁密度对微气候和人体舒适度的影响。结果表明:各植物群落在一天内的相对湿度的变化趋势为先降低后增长,其中以中低郁密度为代表的植物群落相对湿度最高,为71.4%;四组样地的人体舒适度都在上午呈现显著的增长趋势,之后趋于平稳,其中高郁密度的植物群落的温湿指数最高,为25.65。具有中郁密度的植物群落产生的降温增湿作用明显超过其他配置的植物群落,全天人体舒适度评级基本是“冷”。所以,中郁密度的植物群落能够更加有效地改善微环境,更加适合春季人们的日常游憩。

In order to study the influence of different plant community spaces on human comfort, the microclimate data of Shizishan Park in Anqing City were measured to study the influence of canopy density of plant community on microclimate and human comfort. The results showed that the relative humidity of each plant community decreased first and then increased in a day, and the relative humidity of plant communities represented by mid-low canopy density was the highest(71.4 %). The human comfort of the four plots showed an aboriginal growth trend in the morning, and then stabilized. The temperature and humidity index of plant community with high canopy density was the highest, which was 25.65. The study found that the cooling and humidifying effect of plant communities with moderate canopy density was significantly higher than that of other plant communities, and the whole-day human comfort rating was basically ’cold’. In summary, plant community with medium canopy density can improve the microenvironment more effectively, which is more suitable for people’ s daily recreation in spring.
