城市热岛城市热岛 【城市热岛l城市中心地区的气温较周围外部较高的一种现象。其强度以城区平均气温与郊区平均气温的差额表示。一般大城市的年平均气温比郊区高0.5一1.0度,冬季平均最低气温约高1一2℃。由于城市路面和建筑材料大多数反射率小,热传导和热容t较大,在夏季阳光照射下,混凝土平面的气温比大气温度高8℃,比柏油路面高17℃,兼之城区工厂林立、人口密集,交通繁忙,大t的C仇排放到大气中,破坏了原来的生态平衡,导致城市温度过高。如果对城市勾划等温线,气温自城市中心向四周降低,如同海洋上的岛屿高出海平面的情形,故通常用“城市热岛”来描述城市气温的这种变化现象。热岛的存在与消失与风速有很大关系,风速在6In/秒,城乡温差最明显,风速n而秒时热岛消失。城市热岛的形成是城市环境恶化的信号,采用何种手段和措施以避免热岛形成或降低其强度,是当前环境保护的一大课题,也是改善城市环境的一个突破口。
