摘要

利用卫星热红外数据，研究了Jharia煤田土地利用和土地覆被变化对地表温度的影响。利用2005年和2013年的大气校正参数和改进的地表发射率(LSE)模式，采用通用的地表温度检索算法，得到了精化的地表温度。观测结果表明，地表温度以1.05°C的速率升高，不同LULC单元间地表温度存在显著差异。不透水土地(包括荒地和聚落)的增加导致总体平均地表温度的增加。这表明地表温度上升与地表温度变化密切相关。

Impact of land use dynamics on land surface temperature in Jharia coalfield

This study attempts to show the impact of changing land use land cover (LULC) on land surface temperature (LST) in Jharia Coalfield using satellite thermal infrared data. The refined LST was derived by versatile LST retrieval algorithm using atmospheric correction parameters and improved land surface emissivity (LSE) model for two years i.e. 2005 and 2013. It was observed that LST increased at the rate of 1.05°C and significant differences in LST exist over different LULC units. Increase impervious land including barren land and settlement resulted in increase in the overall mean LST. This showed that rising LST is strongly correlated to LULC changes.
