Study on Effective Management Plan by Characteristics of Landslide Occurrence Area in Korea National Parks

This study collected data on 474 sites that occurred in national parks until recently and analyzed the physical characteristics of each landslide occurrence factor, we suggested the criteria for restoration and monitoring of landslide occurrence areas. Landslides were analyzed to occur frequently in national parks under condition of altitude, slope, position, aspect, forest type, parent rock, cross slope, vertical slope, width, length and area. Based on the analysis results, it was classified into 1 place of artificial restoration, 20 places of partly artificial restoration 1 place of partly artificial restoration, 352 places of natural restoration and 100 places of restoration completed by the criteria of restoration plan. Also, according to the criteria of monitoring plan, it was classified into 56 sites for short-term monitoring, 109 sites for medium-term monitoring, 209 sites for long-term monitoring and 100 sites for restoration completed. If we establish and accumulate restoration methods, it will be effective in preserving and managing the beautiful natural environment of national parks which has a very high conservation value both in landscape and ecology, and in minimizing casualties and property damage.&#x0D; </jats:p
