Analysing the reports of disaster-related, average annual death of lives due to the meteorological disasters amounted to be 250, of which about 90 were due to landslide. According to the last 10-year reports, the average area of landslide occurred reaches 275 hectares per year in Korea. The total cost for rehabilitation could annually require more than about 2 billion Won (about US$ 2.5 million). The basic countermeasure policy against such heavy disasters should be definitely taken on prevention rather than rehabilitation after being damaged. However, prevention countermeasures against landslide-related disasters have not been strengthened in Korea although being important. Areas of high landslide hazard must be designated with increase in number from current 10 (35 cities and counties) to 17 (68 cities and counties included : Table 3). Number of regional Erosion Control Stations taking full charge of rehabilitating works on the damaged land resulted from landslide disaster has to increase from currently 15 stations to 25. The stone buttressed terrace structures on the hillside slopes, being typical erosion control measures in Korea have been recently recognized as one of the most effective rehabilitation measures for the land damaged by landslides.

The purpose of this study was to evaluate the effect of rehabilitation measures on the fired woodland of Chesuk-bong in Mt. Chiri through the vegetation structure and comparison of growth pattern between natural seedlings and transplanted Abies koreana seedlings. It was also discussed the rate of standing and fallen trees of dead conifers in the management strategy for vegetation regeneration and protection of sub-alpine area. In this fired woodland, shrub layers consisting of Weigela subsessilis, Sambucus williamsii var. coreana, Rhododendron schlippenbachii, R. mucronulatum, Tripterygium regelii, and etc. were gradually expanded, and tree species such as Betula ermani, Sorbus commixta, Acer pseudosieboldianum, and Malus baccata var. mandshurica were also regenerated. The growth of height and crown width of Abies koreana seedlings transplanted for vegetation regeneration were a little lower than those of natural seedlings. The seedlings of A. koreana transplanted in this fired woodland grew about 50.6% normally, but the others had multi-branched or growth stopped by death of terminal shoot. Because the number of dead conifers by fire tend to be gradually increased as time passed, it can occurs to the soil erosion and landslide by weakness of the cohesion and resistance of soil. Therefore, it is consider that rehabilitation measures projects of the fired woodland in subalpine area may be more prevention a natural disaster like soil erosion, flood and landslide.

The purpose of this study was to analyze the process of natural plant establishment and revegetation on the slopes of landslide scars, both untreated(l4 plots) and treated plots (14 plots) with rehabilitation measures in 1993 and 1994 at Yongin Hwaseong-gun region. While total of 61 species were identified at surveyed sites. in the region, the pioneer species on landslide scars were Lespedeza cyrtobotrya, Arundinella hirta, Artemisia princeps, Pteridium acquilinum, Erigeron canadensis. Rubus crataegifolius, Stephanandra incisa etc. The species diversity (H') and evenness(E') of the untreated scars were greater than those of the treated scars. Similarity indices in the untreated scars were higher than those in the treated scars, and succession indices showed similar value in both areas. As a conclusion, this study shows that the untreated scars were more influenced by the around-vegetation, and the native vegetations(plants) like Lespedeza cyrtobotrya, Arundinella hirta. Miscanthus sinensis, Artemisia princeps, Pteridium acquilinum, Erigeron canadensis. Rubus crataegifolius, Stephanandra incisa ete. could be more effectively used as plant vegetation for rehabilitation of landslide scars.
