Forest Change Detection Using Multi-temporal Remotely Sensed Data in Phu Luang Wildlife Sanctuary, Northeast Thailand

摘要

The main functions of the Wildlife Sanctuary are to conserve forest ecology and to maintain a rich habitat wildlife species. Remotely sensed data provides the updated information on the change and dynamics of the Sanctuary. The objective of this study is to periodically monitor the forest change and to identify the plant community in the sanctuary. Aerial photo acquired in 1976, Landsat data in 1998 and 2005 were used to produce the land use patterns and its changes. The field investigation was conducted to verify the interpretation and to the inventory the plant community and sub community of forest types including its profile diagram. In addition the GIS database of land use pattern was established for the years 1976, 1998 and 2005. Further analysis was digitally performed to create the change detection maps. The results obtained indicate a significant change of forest acreage between 1976-1998 and 1998-2005. The forest types and the plant community were identified within intensive plot observation.
