内容 研究概要:The area of forest in Northeast Thailand decreased by about 300f the area of the region in 30 years from 1961. To prevent further loss of forest, many reforestation projects have progressed significantly in the last decade. However, forest areas estimated from satellite images continue to decline and do not reflect recent expansion of tree plantations. This is partly due to the difficulty of distinguishing newly planted forest land from idle land and upland fields by remote sensing. This study aims at monitoring and mapping recent reforestation in Northeast Thailand based on the results of a questionnaire survey, available databases and national statistics, as a preparatory step to combining remote sensing technology with various types of field survey. NETVIS, an integrated GIS developed by the authors, which incorporates the Village Database and agricultural statistics as its primary data, is applied to this study.
