heat island effect

The heat island effect causes cities to be several degrees warmer than surrounding areas, increasing energy demand.热岛效应导致城市温度比周围地区高出好几度，从而增加了能源需求。

Strategies for mitigating the heat island effect include increasing vegetation cover and using reflective surface materials.缓解热岛效应的策略包括增加植被覆盖和使用反射性表面材料。
