摘要：
Present study was carried out to classify and map the mangrove vegetation as well as erosion and accretion rate along coastal tract of Bhitarkanika, east coast of India using Landsat 7 and 8 satellite data from the year 1989 to 2013.The study resulted different classes like dense mangroves, sparse mangroves and mangroves scrub of mangrove environment. Erosion and accretion rate of Bhitarkanika coast were identified through supervised classification technique. Results of classified image concluded that the changes of sparse mangroves were +2892.78 ha, dense mangroves -350.55 ha. and mangrove scrub +1792.35 ha. Similarly the rate of erosion was 35.6238 sq. km. towards Gahirmatha beach and the deposition of 8.2134 sq. km. near the Maipura river of Bhitarkanika ecosystem from 1989 to 2013.
