PERUBAHAN PENUTUPAN LAHAN DI SUB-SUB DAS AMANDIT

Abstract

The aims of this research is to identify, classify and map landcover in Amandit Sub Sub Watershed using Landsat Imagery that acquared in 1992, 2000 and 2010, and analyzing landcover changes in Amandit Sub Sub Watershed in 1992-2000, 2000-2010 and 1992-2010 period. Furthermore, the data changes in landcover extracted by the method of stacking and overlapping pivot table analysis (cross tab). The results of the analysis of landcover changes clearly show that the Bushes and the moor are both landcover classes that experienced the greatest rate of change during the period 1992-2000-2010. Both of them contradictory, bush shrub widely experienced the greatest increasing, while the broad moor experienced the greatest reduction. Both landcover maps and landcover change matrix, also showed the emergence of two new types of landcover in 2010, those are the Plantation Forest and the Palm Oil. Throughout the forested areas, both Primary Forest, Secondary Forest, and Swamp Forest, experience a significant reduction in area. Forest except that the width increases. In total, the rate of deforestation in Amandit Sub Sub Watershed over a period of 18 years (1992-2010) is approximately 1519.88 hectares per year
