基于Landsat8和ALOS2的矿区地表温度及形变研究

Research on surface temperature and deformation of mining area based on Landsat8 and ALOS

地表温度和地表形变监测,在生态环境和地质灾害中应用广泛,本文使用大气校正法获取地表温度,利用DInSAR是获取地表形变,并探寻矿区内两者的关联。本文以湖北宜昌作为研究区域,分别统计矿区范围内地表温度和地表形变,进行对比分析。实验结果表明,建筑用花岗岩矿的地表温度高,对于太阳辐射吸收强,磷矿的地表温度低,对于太阳辐射吸收弱;铁矿的地表形变大,玻璃用石英岩和建筑用花岗岩的地表形变小,应加强铁矿区域地表形变监测;露天开采矿区地表温度远高于地下开采,地下开采矿区的形变程度远强于露天开采,研究区内分布的地表温度越低的矿区,其地表形变反而越大。

Surface temperature and surface deformation monitoring are widely used in ecological environment and geological disasters.In this paper,the atmospheric correction method is used to obtain the surface temperature,and DInSAR is used to obtain the surface deformation and explore the relationship between the two in the mining area.This paper takes Yichang,Hubei as the research area,and makes a comparative analysis of the surface temperature and surface deformation in the mining area.The experimental results show that the surface temperature of the granite mine for construction is high,and the absorption of solar radiation is strong;the surface temperature of phosphate rock is low,and the absorption of solar radiation is weak;the surface deformation of iron ore is large,and the surface deformation of quartzite for glass and granite for construction If it is small,the monitoring of surface deformation in the iron ore area should be strengthened;The surface temperature of the open-pit mining area is much higher than that of the underground mining,and the deformation degree of the underground mining area is much stronger than that of the open-pit mining.
