一、调节气候与保护环境绿色植物具有强大的蒸腾作用,可不断向空气中输送水蒸气,提高空气湿度。据分析,绿地的相对湿度要比非绿化区高出10%至20%。植物叶面的蒸腾作用能调节气温,吸收太阳辐射热,对改善城市小气候具有积极的作用。研究资料表明,当夏季城市气温为27.5℃时,草坪表面温度为20℃至24.5℃。冬季,铺有草坪的足球场的表面温度则比裸露的球场
First, climate regulation and environmental protection Green plants have a strong transpiration, can continue to transport water vapor to the air, improve air humidity. According to the analysis, the relative humidity of green space is 10% to 20% higher than that of non-green area. The transpiration of plant foliage can regulate the temperature and absorb solar radiation heat, which has a positive effect on the improvement of urban microclimate. Research data show that when the summer city temperature is 27.5 ℃, the lawn surface temperature is 20 ℃ to 24.5 ℃. In winter, the lawn-covered football field has a surface temperature that is lower than that of the bare course
