Spatial Metrics of Deforestation in Kampar and Indragiri Hulu, Riau Province

Abstract

The Riau Province has been suffering from the highest deforestation rate in Sumatra, Indonesia. Many and various factors haved been discussed as causes of different deforestation types. This research is focused on evaluating the spatial pattern of deforestation in a specific location respresenting a typical deforestation in Riau. The main objective of this study to identify spatial metrics to describe deforestation that occurred in Kamp was ar and Indragiri Hulu regencies.The study divided the deforestation process into 3 periods of observation, . ., 1990– e g 2000, 2000–2010, and 2010–2014. The study based on Landsat satellite imagery aquired in 1990, 2000, 2010, and 2014 as the main data sources. The deforestation was detected using post-classification comparison (PCC) on the basis of 11 land cover classes developed prior to any further change detection. The deforestation was initially derived from reclassifying the original classes into only forest and non-forest classes, and then followed by spatial pattern analysis using Fragstat The shows that spatial pattern of deforestation in Kampar distinctly differs from software. study 2 those occurred in Indragiri Hulu egency for the period of 1990–2014 The spatial pattern of R , particularly . deforestation in Kampar egency re clumped, low contiguous between patch, and high fragmentated. Mea R we nwhile, the spatial pattern in Indragiri Hulu Regency re clumped, high contiguous between patch, and low fr we agmentated. Profile of deforestation in Kampar egency was cathegorized into early deforestation and Indragiri H R R ulu egency as lately deforestation.
