Multi-temporal relationship between surface temperature, land use and normalized vegetation index

Abstract: Land surface temperature can reflect environmental interactions and exchanges between soil, land cover and atmosphere, which is important for studying environmental changes. Nevertheless, research on surface temperature in ecologically fragile saline areas is rare. Thus, in most previous research articles, the main study areas were large agglomerations and other areas characterized by natural phenomena such as erosion. In fact, the study of this parameter is difficult at the local scale because it is influenced by climatic variations and anthropogenic practices that determine land use. In summary, the Atmospheric Correction Model from Landsat data can easily extract surface temperature and explore its relationship with land use and NDVI. Indeed, the variation of the surface temperature is according to the type of land use. This study provides a reference for land use planning, restoration of the ecological environment in round of saline areas. The days of 03/31/1987, 03/26/2000 and 03/28/2015 were chosen mainly for the quality and availability of the images and that the vegetation is ripe at this time of the year.
