摘　　要：根据LandsatTM数据,利用单窗算法对重庆市主城区进行地表温度反演,得出重庆市主城区地表温度场的分布规律,并通过选取样区对地表温度空间分布作了对比分析。结果表明:重庆市城区与近郊温差为4.75℃,城区与郊区温差达9.88℃,城市热岛效应明显;城市地表温度与土地利用类型紧密相关。研究成果对于改善城市生态环境、加强科学规划有重要的参考价值。This paper studies the response of urban surface temperature in Chongqing.According to Landsat TM Remote Sensing,using single-window algorithm to retrieve surface temperature,obtained in Chongqing urban area the distribution of surface temperature and the sample area by selecting the spatial distribution of surface temperature were compared.The results showed that it is close to 4.75℃ with Chongqing city and Peri-urban,and temperature difference between urban and suburban areas over 9.88℃,urban heat island effect is very obvious;The urban surface temperature and land use types are closely related.The research results for improving the urban ecological environment,strengthen the scientific planning of important have important reference value.
