Application of GIS in assessing the overlap between land use planning and forest planning in the mountainous area of Hue city

Abstract

This study was conducted in eight communes of the mountainous area of Hue city after the administrative merger of two levels, with the aim of assessing the overlaps between land use planning and forest planning during the 2021 – 2030 period. Based on the collection of planning data, GIS technology was applied to overlay maps, combined with expert consultation. The results indicate that the total overlapping area reached 18,850.23 ha, accounting for 10.29% of the study area; the matched area was 156,946.95 ha (85.63%); while the area with administrative boundary inconsistencies was 7,479.87 ha (4.08%). The communes of A Luoi 4, A Luoi 1, and A Luoi 5 recorded the largest overlapping areas, reflecting complex topography and boundaries. The identified causes of overlaps include: inconsistencies in administrative boundaries, differences in objectives and timing of planning, limitations in databases and mapping methods, and impacts from planning adjustments.
