| 摘 要： | 为了研究城市不同绿地类型缓解热岛效应的效果大小，在长沙市城区选取4种典型绿地类型的样地及其相邻裸地，进行实地观测获取温度和湿度数据，通过分析，结果表明：降温效应和增湿效应都是乔木林>乔灌林>灌丛>草地；乔木林、乔灌林、灌丛和草地的温度变化指数分别是7.32、6.59、5.33和4.10，湿度变化指数依次为16.87、13.23、9.42和7.61。结论表明：不同类型的绿地因其内部结构和垂直结构不同，降低城市热岛效应的强度不一样，长沙市4种典型绿地类型减缓城市热岛效应强度的大小排序是乔木林>乔灌林>灌丛>草地；为减缓城市热岛效应的影响，在城市绿地建设中，长沙市应加大乔木林、乔灌林建设的面积，减少灌丛和草地建设面积。

| Abstract: | This paper studied four types of green space in urban on the reduction of heat island effect.The authors selected four typical types of green space and their adjacent bare plot in changsha city to carry out field observations of temperature,humidity and obtained data.By statistical analysis,the results showed that:different types of green space had different effects to reduce the urban heat island;cooling effect and humidifying effect were showed that:the arbor forests ' was higher than arbor-shrubberys ' t... |
