摘　　要：随着城市化的迅速发展,城市热岛效应的影响变得日益严重。利用广州地区的Landsat 7 ETM+影像,对热红外波段数据和多光谱波段数据分别进行处理和解译,结合GIS数据,以天河区和番禺区为典型样区分析不同的用地结构与热导效应的相关关系。结果显示热场变化与城市集聚程度有明显的关系,下垫面土地覆被类型是主导因素,热场的强度由高到低依次为:工业区、城市中心区(商业区)、居民区、郊区。With the rapid development of urbanization, urban heat island has a trend of enlargement. Based on GIS data and Landsat-7 ETM＋ images, the thermal infrared and multi-spectral remote sensing data have been delt with and translated. , then the relationship between land use pattern and heat island effect has been analyzed. The results indicate that the heat island can change depanding on concertration of urban space. The style of land use/land cover is the main factor. The intensity of heat island from high to low is industrial area, city center（business district）, residential area and suburban area.
