摘要: 以于田绿洲为例, 以Landsat TM/ETM+图像为主要的数据源, 提取了于田绿洲的土地利用/覆被信息. 利用单窗算法反演了地表温度, 综合分析了2001-2011年间于田绿洲土地利用/覆被变化(LUCC)及其对地表温度的影响, 同时利用像元分解模型得出绿洲植被覆被度, 并分析了其与地表温度的关系. 结果表明: 在2001-2011年的10 a期间, 于田绿洲最主要的土地利用类型是以人类为主导因素的, 同时以自然利用类型向人工利用类型的转化最为显著. 耕地、水体等以人类为主导因素的土地利用类型面积增加了809.65 km2, 盐渍地等以自然为主导的土地利用类型面积减少了758.76 km2, 人为影响是于田绿洲较主要的驱动因素. 于田绿洲土地利用/覆被变化改变了地表温度的空间分布特征, 在土地利用/覆被类型发生变化的区域, 地表温度有升有降, 但总体上地表温度的空间分布与土地覆被类型的空间变化格局存在明显的一致性. 地表温度的变化与植被覆被度的变化有关, 证明了植被在改变下垫面热量分布的格局中扮演着重要作用.

Abstract: Study on the response of surface temperature to land use and land cover change by using remote sensing data is an effective way to monitor and evaluate the environment with the support of remote sensing and geographical information system. Landsat TM/ETM+ image of 2001, 2007 and 2011 were used to acquire the land use and land cover data of Yutian Oasis, Xinjiang. The single thermal infrared band was used to retrieve the surface temperature. Based on the classification and surface temperature data in 2001, 2007 and 2011, the land use and land cover change and surface temperature responses were analyzed in combination. The result shows that the major land utilization and land coverage changes are dominated by human activities, and the most obvious change is from original utilization to artificial utilization. The area of farmland and water body has increased 809.65 km2; the area of salinized fields has decreased 758.76 km2. With the change of land use and land cover, the surface temperature patterns are also changing obviously. Different land utilization and land coverage type has different surface temperature pattern. Vegetation plays a vital role in the change of underlying surface heat distribution pattern.

Key words: Yutian Oasis, land use/cover change, dynamic change, land surface temperature
