DIVERSITY IN TREE SPECIES AND IT S IMPACT ON URBAN CLIMATE THE CASE OF AHMEDABAD

Abstract

Ahmedabad is located in north-east position of Gujarat state of India, geographically extreme positions 230 1 N (north), 220 56 N (south),72030 E (west) and 720 41 E (east) and average 53m height above sea level. Pre-May 1970, it was capital to Gujarat. This city was established by Sultan Ahmed on bank of Sabarmati river and has own very interesting history.It is district place neighboring to Mehsana, Surendranagar, Gandhinagar, Anand and Kheda districts. Once upon a time, Ahmedabad was globally known as Manchester of India as there was lot of textile mills in this city.As per Census 2011, population of Ahmedabad is 5.5 million and its urban/metropolitan population is 6.3mllion. It is seventh largest metropolitan city of India.It is also judicial capital of Gujarat state. This city has rich industrial establishments since beginning having main industry of textile mills, pharmaceuticals,engineering and latest addition of automotive industry. This city is well-known due to corporates like Nirma, Torrent, Adani, Cadila, and education institutes like IIM, IIT, Gujarat University, Nirma University and of-course for Sardar Sarovar Project which connects state s different area with Narmada River. newlineBeing resident of this city, we have taken up research project to identify and summarize tree species of urban Ahmedabad and its climatic effect. Our work deals with 225 tree species from total 50families. While reviewing, 5major tree species are Azadirachta indica A. Juss, Polyalthia longifolia (Sonn.), Holoptelea integrifolia (Roxb.) planch, Delonixregia (Bojer. ex. Hook) and Acacia nilotica (L) wild ex. Delite ssp. Indica (Benth) and total tree density of 618,048. We have studied environmental pollution with respect to tree density, specifically on Respiratory Suspended Particulate Matters, Suspended Particulate Matters, Sulfur Dioxide and Nitrogen Oxides in individual zone-ward wise. There are many areas which are still in bad situation even today, this due to lack of infrastructure and awareness in habitants.
