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

Penelitian ini menjelaskan pola deforestasi yang terjadi di Kabupaten Riau (Indragiri Hulu dan Kampar) selama periode 1990 hingga 2014. Penelitian ini mengungkapkan tentang pola perubahan dan konversi lahan hutan menjadi penggunaan atau tutupan selain hutan selama periode tersebut.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 was to identify spatial metrics to describe deforestation that occurred in Kampar and Indragiri Hulu regencies.The study divided the deforestation process into three periods of observation, i.e., 1990???2000, 2000???2010 and 2010???2014. The study based on Landsat sattellite 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 software. The study shows that two spatial pattern of deforestation in Kampar distinctly differs from those occurred in Indragiri Hulu regency, particularly for the period of 1990???2014. The spatial pattern of deforestation in Kampar regency are clumped, low contiguous between patch and high fragmentated. Meanwhile, the spatial pattern in Indragiri Hulu regency are clumped, high contiguous between patch and low fragmentated. Profile of deforestation in Kampar regency was cathegorized into early deforestation and Indragiri Hulu regency as lately deforestation
