ABSTRACT

This study examined ecological network change affected by the 2020 invalidation of decisions on urban parks with a focus on Busan. The analyses were conducted to five scenarios using FRAGSTATS. The green space in scenario 1 assuming all development for unexecuted urban park would decrease by 7,339.75 ha compared to scenario 5, which assumes the entire conservation of unexecuted urban parks, and the fragmentation of the ecological space in scenario 1 increased. In scenario 1, 8.06% of the total area of core habitats and 28.23% of connectivity would decrease. However, scenario 3, which assumes the conservation of environmentally sensitive areas of unexecuted urban parks, can achieve 94% of green space and 95.6% of the connectivity of the scenario 5. Scenario 3 has effects similar to scenario 5 in terms of defragmentation. Thus, conservation of environmentally sensitive areas in parks is critical and effective in maintaining ecological networks.
