其他摘要：Hyderabad city, the fourth most populous city and sixth most populous urban agglomeration in India is emerging into a megacity with the population set to cross the 10 million mark by 2015. The city is currently in the midst of unprecedented urbanization as it has grown into a cyber-capital, and is now known as the tricity of Cyberabad- Hyderabad and Secunderabad. Commanding a massive area of 1905 km2, the city suffers from a host of problems including heavy population growth, over-use of basic amenities and resources, sprawl, depletion of ground water and climatic changes attributed to enhanced greenhouse gases. This study evaluates the growth of the urban built up areas within the city using remote sensing and GIS, apart from analyzing the temperature profile across various land use and land cover. Landsat 5 TM data of 1989, 1999 and 2009 were used to understand the temperature changes over different land use and land cover. The study shows a 67% loss in water bodies while the urban built up areas have grown by 270%. The temperature profile also shows a dip in temperature while encountering water bodies, gardens and parks.
