Abstract

This study examined the relationship between Land Surface Temperature and various spectral indices in Dera Ghazi Khan division of Pakistan to assess landscape characteristics and ecological health. This study used satellite images to detect temperature variation and urbanization-influenced land cover patterns using remote sensing data during 2013–2023. Estimated results revealed that Land Surface Temperature was significantly linked with spectral indices over the study’ period. The results showed a continuous increase in urban intensity contributing to an increase in surface temperature to 47.19 °C by 2023. It was also found that due to cooling effects, there is a negative relationship between the Normalized Difference Vegetation Index and the Land Surface Temperature, whereas positive values exist concerning the other indices. These findings indicate the higher temperatures for built-up areas, barren land, and water-reduced bodies. Moreover, findings of various spectral indices revealed the significant temperature differences and changing land covers. In addition, the results of land cover changes showed how temperature variations are influenced by urbanization and health status. The findings of this study will be helpful for government and concerned policy makers in promoting sustainable land management practices to mitigate climate change and local environmental protection measures.

期刊介绍： Gondwana Research (GR) is an International Journal aimed to promote high quality research publications on all topics related to solid Earth, particularly with reference to the origin and evolution of continents, continental assemblies and their resources. GR is an "all earth science" journal with no restrictions on geological time, terrane or theme and covers a wide spectrum of topics in geosciences such as geology, geomorphology, palaeontology, structure, petrology, geochemistry, stable isotopes, geochronology, economic geology, exploration geology, engineering geology, geophysics, and environmental geology among other themes, and provides an appropriate forum to integrate studies from different disciplines and different terrains. In addition to regular articles and thematic issues, the journal invites high profile state-of-the-art reviews on thrust area topics for its column, ''GR FOCUS''. Focus articles include short biographies and photographs of the authors. Short articles (within ten printed pages) for rapid publication reporting important discoveries or innovative models of global interest will be considered under the category ''GR LETTERS''.
