Application of remote sensing and GIS to assess forest cover change during the 2010-2015 period in Huong Khe district, Ha Tinh province
Tran Quoc Vinh, Nguyen Thuy Ngan
SUMMARY
The application of remote sensing and GIS overcomes many limitations of traditional methods and is particularly effective in assessing land use changes in the areas where travel is difficult. The objective of this study is to assess the forest cover change during the period of 2010-2015 in Huong Khe district, Ha Tinh province. Landsat satellite data of 2010 and 2015 were used to establish forest cover maps for those years, with an accuracy represented by Kappa coefficients of 0.89 and 0.91, respectively. The map of forest cover change for the period of 2010-2015 was established using the GIS overlaying method. During this period forest cover area of Huong Khe district decreased by 7262.46 ha, meanwhile there was only 392.6 ha of newly planted forest. Main causes of deforestation in the district included forest fire, indiscriminate logging, cutting forest for milpa cultivation, conversion of forest to industrial or fruit trees and construction of forest product processing plants.
Keywords: Remote sensing, GIS, forest cover change.
