临空煤田火区地表温度变化特征及驱动机制
Characteristics and Driving Mechanisms of Land Surface Temperature Variations in the Fire Zone at the Coalfield-Atmosphere Interface
摘要
Abstract
In order to explore the influence of spontaneous combustion of coal seam in coalfield fire area on the mining area and surrounding environment,the Qiquan Lake mining area was taken as the research area,and the Landsat 7/8 image covering the research area was used as the data source.The radiative transfer equation method was used to invert the surface temperature data of five periods.The calculation results were compared with the MODIS LST observation results.The surface temperature variation characteristics of the Qiquan Lake mining area and its surrounding environment from 2012 to 2022 were studied.Using the geographic detector,the land surface temperature change data and the data of various factors are spatially matched and statistically analyzed.The results show that the surface temperature of Qiquan Lake mining area and its surrounding environment presents a dynamic distribution from 2012 to 2022.The areas with higher temperatures are concentrated in the mining pit area of the mining area,and the surface temperature of the surrounding area decreases slowly with the increase of the distance from the mining pit area.Land use,surface albedo and vegetation index have a high degree of influence on surface temperature,while slope and aspect have a small degree of influence.关键词
