Land surface temperature plays an essential role in estimating radiation budgets, in heat balance studies and as a control for the climate dynamics and modeling frame, and in studying the impact of LULC changes at regional level. The paper provides a comprehensive evaluation of the relationship between Land use and Land Surface Temperature (LST), through a landscape dynamics assessment based on multi-source and multi-sensor remote sensing technologies. In particular, the study was performed using the Landsat satellite 5 TM, ETM and OLI 8 data for three different dates (1985, 2001 and 2017) and aimed to assess the land use/land cover changes effects on the LST distribution in the region of Taroudant, Morocco. Spatial and statistical analysis and comparison of maps generated from remotely sensed data using GIS indicate the existence of different changes in the Taroudant region between 1985 and 2017. These changes are predominantly characterized by an increase in built-up areas and bare ground and a decrease in natural areas (vegetation, forest ...). The average temperatures in 1985, 2001 and 2017 in open forests were 32,74°C, 34,37°C and 39,17°C respectively. The farming greenhouse temperatures were 24.09°C, 28.5°C, 35.58 °C, and barren soils 37.14 °C, 38.38°C, 40.01°C. The average land surface temperatures of farming lands were 24.31 °C, 27.87°C and 28.61°C, respectively. As a result, the soil artificialization and everything associated with such as greenhouse gas emissions, and abusive consumption of agricultural and natural land, are likely to be the origin of environmental problems and climate change marked mainly by these changes in surface temperature and irregular rainfall and unprecedented periods of drought.
