Dinamika Tutupan Lahan Kawasan Hutan Lindung Air Telang Menggunakan Teknik Overlay Multitemporal

Abstract

Identification of various types of land cover in the Air Telang Protected Forest has been carried out during the period 1989-2013. The method used in identifying the dynamics of land cover in this area is the survey method of land cover changes based on time series remote sensing data in 1989, 2001 and 2013. Analysis of data in this study was in the form of analysis of land cover changes in Air Telang Protected Forest using GIS with a two-period overlay of time series technique namely the period 1989- 2001 and 2001-2013. The results showed that there were around 55.11% (6,978.00 ha) of primary forest that still survived during period 1 (1989-2001) and around 44.8% (5,671.53 ha) in period 2 (2001-2013). The area of primary forest increases because of the succession of several types of land cover, such as secondary forests, coconut plantations, swamp shrubs, ponds and water bodies into primary forests. The reduction in primary forest area is caused by the conversion of forests by communities into coconut plantations, oil palm plantations and ponds, and illegal logging. The Air Telang Protected Forest area needs to be restored in an effort to maintain its function as a protected forest. Keywords:
