Abstract: Remote sensing (RS) and geographic information system (GIS) techniques have been extensively used over the world for the study of chronological changes in land use/land cover (LULC) and land surface temperature (LST). Moreover, understanding the relationship between them is the most important to manage lands. This study explores the application of RS/GIS for identifying LULC change and assessing its impact on LST using temperature-vegetation index (TVX) space in the east sub-basins of Urmia Lake basin, Iran. The results showed that most changes due to agricultural activities were observable as the pixel migrated from the high temperature-sparse vegetation condition to the low temperature-dense vegetation condition from 1989 to 2002; while, in addition to agricultural activities, due to urbanisation and human activities, the pixel migrated from the low temperature-dense vegetation condition to the high temperature-dense vegetation condition from 2002 to 2011 in the TVX space for entire case study. In general, the LULC change is a significant factor for LST increase or decrease, and LST changes mostly related with LULC changes in the study area.
