Spatial Patterns Analysis of Deforestation in Palopo Municipality and East Luwu Regency

[摘要] Deforestation is an activity or process that converts forest cover into non-forest land cover with a certain pattern. Palopo and East Luwu are two districts in South Sulawesi deforested due to the demand of the human need to convert the land into settlements, infrastructure and timber harvesting. This research was conducted to find out the temporal spatial pattern in dealing with deforestation. Analysis of spatial patterns using fragstat software with input data i.e. land cover shapefile data in 1990, 2000, 2010, and 2016 that produced contour in metrics, and its subdivision in metrics. Temporal spatial patterns of deforestation are built by combining three spatial metric values. Based on the description of deforestation analysis in Palopo Municipality covering 852,96 ha and East Luwu with 86,963,46 ha, Palopo Municipality experienced the highest deforestation from 1990 to 2000 amounted to 451.69 ha and continued to decline in the period of 2000-2010 and 2010-2016. Deforestation in East Luwu Regency is the highest in the 1990-2000 period which is 38.655,05 ha. Deforestation in East Luwu Regency has higher contiguity than deforestation occurring in Palopo Municipality indicating that the occurrence of deforestation occurring in East Luwu Regency occurred directly from previously degraded areas to adjacent forest areas. Palopo and East Luwu Regency show fragmentation rates that tend to decrease due to the decreasing number of fillings that are formed the largest combination of spatial patterns occurring during the observation period was the spatial pattern of deforestation grouped, with high density (not fragmented) in 50 villages (61.72%).
