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 was to identify spatial metrics to
describe deforestation that occurred in Kampar and Indragiri Hulu regencies.The
study divided the deforestation process into 3 periods of observation, e.g.,
1990–2000, 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 software. The study shows that 2 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 were clumped, low contiguous between patch, and high
fragmentated. Meanwhile, the spatial pattern in Indragiri Hulu Regency were
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.
