Spatial Analysis of Land Use Change in Relation with The Use of Zoning Area at Gunung Halimun Salak National Park

Abstract

Gunung Halimun Salak National Park (GHSNP) is the largest tropical rain forest ecosystem in Java. GHSNP ecosystems play an important role as watersheds protection, microclimate, wildlife conservation, research, environmental education, ecotourism and preservation of local culture. A variety of land use activities by communities that does not comply with the zoning plan of GHSNP will cause degradation of the forest ecosystem. However, its change should be monitored to control forest degradation. This study aims to: (1) analyze land use changes in the period 2000-2010, (2) analyze the factors that drive the land use changes from forest to Non-forest, (3) predict the use of land in 2026 using spatial models of land use change, (4) formulate directives refinement for land use planning GHSNP. Land use change modelling has been introduced to predict future pattern of change. CLUE-S was used to simulate land-use change based on the driving factors. The results of the analysis showed there is changes in land use in the 2000-2010 period. The most extensive land use decline is forest that decreased by 5,5%. On the other hand, the land use that extensively increase is field that rise 2,21%, rice field that rise to 1,46% and bush that increased 3,4%. The main pattern in land use change is from forest into mixed garden, field and bush. (2) According to the regression analysis, the factors that drive the land use changes from forest to Non-forest is density population. (3). Prediction result show forest landuse increased occurs in scenario 2 and 3. The landuse of a mix garden, field, paddy field and shrubs increased in the scenarios currrent conditions and scenario 1. CLUE-S model is simulated in this study has an accuracy of 88.53%. Alternatives of policy that selected based on the study for the refinement of landuse planning is forest restoration policy on core zones, jungle zones and rehabilitation zones, namely the restoration efforts of forest from mixed garden, fields, paddy field and shrubs. This policy can reduce 9.23% of the incompatibility between land use and zoning plan.
