城市“热岛效应”日益受到人们的关注,它是现今困扰都市居民的主要环境问题之一。表现为城市中的气温明显高于外围郊区,这种“热岛效应”是城市化发展带来的副产品。而在其形成的主要原因中,最不容忽视的因素恐怕就是城市里高楼林立,通风能力被大大削弱,从而形成了一个个闭合的高温中心。 Urban “heat island effect” has drawn increasing attention. It is one of the major environmental problems plaguing urban residents today. The performance of urban temperatures is significantly higher than the outer suburbs, this “heat island effect ” is a by-product of urbanization. In the main reason for its formation, the most neglected factor probably is the high-rise buildings in the city where the ventilation capacity is greatly weakened, thus forming a closed high-temperature center.
