Exploring the spatial pattern of urban heat island formation in relation to land transformation: A study on a mining industrial region of West Bengal, India

Abstract

The Earth surface has transformed a lot by various deliberate and inadvertent anthropogenic activities; most profound among them are perhaps the changes in the land use land cover pattern of any area. It is considered to be responsible for many irreversible changes in the regional heat budget and water balance. Expansion of the built up area found to be modified the surface interaction of solar radiation thereby alters the surface temperature pattern of any region. Present study has been carried out in the Jamuria community development (C D.) block of West Bengal to examine the relation between land use land cover (LULC) change and its impact on the rising land surface temperature (LST) by using multi temporal satellite data. Urbanization, industrialization and mining activity in the study area found to be alters the LULC to a great extent which seems to be responsible for the general rise in the ambient temperature and micro climatic variation. Definite association has been found to be exists between LST and LULC pattern of the study area. Rise in the LST pattern are considered to be spatially associated with those areas where the intensity of land use change is maximum. Correlation between them, land use indices like normalized difference vegetation index (NDVI), normalized difference built index (NDBI) etc and transect profile also confirmed these facts.
