ANALYSIS OF NATURAL ENVIRONMENTAL CHANGES USING REMOTE SENSING AND GEOGRAPHIC INFORMATION SYSTEM (GIS): CASE AREA OF MOEYUNGYI WETLAND WILDLIFE SANCTUARY AND ITS ENVIRONMENT, BAGO REGION IN MYANMAR
Abstract
- Moeyungyi Wetland Wildlife Sanctuary is located about 6 furlong away from the YangonMandalay old high way, near Pyinpongyi village, Bago and Waw Township, Bago Region. Moeyungyi Wetland WS is a man-made wetland. It was constructed in 1904 and it provides water flow into Bago-Sittaung canal. Many years later, the reservoir changed naturally into wetland, notified as a wildlife Sanctuary in1988. The maps of the classification of the land use in wetland area are important for natural resource management. The changes of the land use in the natural wetland area have been tested by the accuracy of remote sensing and GIS techniques based on UTM map and Landsat TM satellite data (2006-2019). The maximum likelihood supervised classification technique was applied for land cover classification such as land areas including paddy field and swamp areas, water body area, natural vegetation area consist of shrubby grass. There are many environmental changes year by year. The main water body areas gradually declined during 2006-2015 but water body area sharply enlarged in 2019. Natural Vegetation gradually reduced and shrubby grass areas mainly in wetland decreased during 2006 and 2019 due to deforestation and land use changes which paddy field areas gradually increased duration of 18 years. Over all, not only the original wet land area, but also the whole surrounding area had been transformed into land area by 2019 image analysis. Therefore, the natural ecosystem of wetland can change in the future. If the ecosystem of wetland will be changed, the biodiversity of birds and other species will decrease because the ecosystem of wetland area is not suitable for their habitat.
