摘　　要：城市热岛强度分区是城市通风环境改善的前期准备工作。通过空间信息技术方法,提取不同土地类型,并结合建成区热岛强度指数划分武汉市热岛及冷空气生成区。结果表明:用地类型与地表温度存在明显的相关性,大部分水域处于低温区及次低温区,高温区不存在林草地和耕地,城市建设用地主要分布在高温区内;热岛区域大部分分布在武汉市主城区范围内,冷空气生成区位于城市热岛的周边,主城区范围内的大型湖泊、河流和公园绿地对热岛进行分隔。由此提出,对武汉市各个气候功能片区采取分类规划改善策略。Thermal environment study is a preliminary research for urban ventilation environment study. The paper extracts the different land use which based on the spatial information technology, and combines the in-dex to divide the urban heat islands and cold air areas of Wuhan. It indicates that there is a strong relationship between land use and land surface temperature. Most of the waters are in low temperature areas. The grass land and cultivated land are not existed in high temperature areas, but the urban construction land is mainly distribu-ted in high temperature areas. As for the Wuhan City, most of the heat islands exist in the main urban areas, and the cold air generated area is located in the surrounding of urban heat islands. The heat island in the main areas are separated by large lakes,rivers and the park green space. Lastly, this paper presents the planning strategy of each climate zone in Wuhan.
