根据Landsat TM数据，利用单窗算法对洞庭湖区域进行地表温度反演，得出湖区地表温度的分布规律。结果表明：温度反演成果可靠误差小，湖区温度比周边植被、裸露地地表温度偏低，湖泊冷湖效应明显；地表温度与土地利用类型紧密相关。研究成果对于改善湖区生态环境、加强科学规划洞庭湖具有参考价值。

According to Landsat TM data, the single window algorithm was used for inversion of surfacetemperature in Dongting Lake area, and the distribution law of surface temperature was concluded .The temperatureinversion results were reliable with small error .The surface temperature of lake area was lower thanthat of surrounding vegetation and open ground showing obvious “cold lake effect”.The surface temperaturewas closely related with the land use types.This research results had important reference value for improvingecological environment and strengthening scientific planning of Dongting Lake .
