  • The purpose of this study is to identify the fragmented points of mountain ranges in Daegu metropolitan city using New Sangyeongpyo (Chart of Mountain Ranges), road system map and GIS spatial analysis, and to prioritize the identified fragmented points for restoration based on quantitative assessment. Moreover, this study proposes restoration plans reflecting the assessment results and characteristics of each fragmented point. The results of this study are summarized as follows: First of all, analysis of the distribution of mountain ranges in Daegu metropolitan city showed that jimaek and semaek in Daegu account for 2% of all mountain ranges in the country, implying that the mountain ranges of Daegu do not hold significant ranking on a national level. However, it was found that numerous fragmented points are appearing due to roads. According to the analysis, 35 fragmented points were identified, of which 15 were found to be restorable. In terms of restoration potential and involved risks, assessment results of the 15 fragmented points indicated that 6 points are at Grade I, 3 points are at Grade II and 6 points are at Grade III. Therefore, a methodology of restoring fragmented mountain ranges was proposed through three suggestions of restoration plans that consider the characteristics of each fragmented points. The results of this study are expected to be highly useful as basic data for effective restoration of mountain ranges in connection with mountain range restorations and relevant projects implemented on a national level in the future.

  • This study was conducted to clarify the distribution and fragmented points of mountain range and to select priority points for restoration by assessment in Daejeon. There were ten Semaek of mountain extended from three Jimaek in Daejeon. As a result of overlapping the main mountain ridge with a network of roads, twelve points out of total thirty-one fragmented points were chosen as practical points for restoration. We developed index and model to assess twelve practical points for restoration. All points were classified into three grades, four points of grade I, five points of grade II and three points of grade III. From this study, we proposed differentiated restoration plan for each grade. Further studies on development of more objective assessment and detailed methodology should be needed to prepare effective restoration plan.

  • Since enactment of the Baekdu-Mountain Range protection law in Dec. 31st 2003, great interest arose in recovery of the natural environment in the Baekdu-Mountain Range. Since the Baekdu-Mountain Range has formed boundaries between different regions and it is the mountain that crosses our country from East to West, there are so many roads that penetrate this area. Slopes made by the construction of roads have poor foundation for the growth of vegetation and it takes a long period to restore only with natural restoration force. For this reason, various methods of revegetation to restore the damages are implemented but until now, revegetation of domestic soil cutting slopes are mainly covered by foreign import grasses to stabilize and cover grounds early. As we depended upon foreign import grasses for slopes revegetation, the landscape did not match in harmony with surrounding vegetation and therefore, we could see that these foreign grasses are withered in 2~3 years after the revegetation works and slopes become barren again. However, currently, there are no applicable standards for designs of green hill, desirable revegetation methods for the hill areas, roads and recovery models. Therefore, in this study, we investigated the status of revegetation plants and revegetation methods for the hill areas of the Baekdu-Mountain Range (azimuth, degree of tilt, and tilted places). Based on this, we attempted to find the desirable recovery models for the hill areas of the Baekdu-Mountain Range.

  • This study was conducted as a restoration research in a mountain stream of hydrologic cycle system, which is a type of microsites purposely changing vegetation. The status of vegetation in the three experimental sites, water purification site, small dammed pole site, and aquatic plant restoration site, and one control site within the area of the mountain forest stream were investigated in three different periods, namely before sites restoration, year of sites restoration, and year after sites restoration. After one year of restoration, number of vegetation was increased in the small dammed pool and control site respectively. Vegetation coverage ratio of Zizania latifolia was increased at the water purification area. The effects of habitats restoration appeared to be good a year after the restoration of the experimental sites, in terms of families and species composition of the introduced vegetation, and stream flow. Therefore, the results of the study strongly suggest that fairly effective ways to restore and reproduce degrading mountain hydroecological habitats are by way of forming pool sites and small dams in intermittent mountain streams and re-vegetating with selected plants.

  • This study intends to suggest the improvements for the legal systems related to the conservation of mountain ridge areas. The 4 legal systems directly related to the conservation of mountain ridge areas are reviewed and the current conditions of adaptive reuse of mountain areas and destroy cases in Hwasung are examined. For solving the problems on the basis of the analysis, three proposals for the improvement on legal systems are suggested. First, the integration of present dual legal systems related to adaptive reuse of mountain areas on the assumption that the related criteria and provisions should be amended, second, activation of the legal systems such as natural landscape district and natural landscape review to make up for the laws related to adaptive reuse of mountain areas, third, the enactment and application of the ordinances related with the 'mountain area management law'.

  • This study is to propose development direction of sang-dang mountain fortress toward the utilization of historical and cultural heritage as tourist attraction through the consideration of problems on sang-dang mountain fortress development. First of all, the historical significance, development project and status of Sang-dang mountain fortress was figured out. Furthermore, using pattern and general user's view was understood through the questionnaire survey then research on the actual condition of traditional korean village was performed. The ongoing development project focusing on restoration of cultural properties to its original state through an archaeological excavation investigation turned out to be lack of consideration on the utilization of sang-dang mountain fortress such as tourists inducement. Furthermore, the measures on traditional korean village which has been a problem by forming commercial area recklessly have been left off. Therefore, additional development plan is required on convenient and amenity facilities and rest places for visitors including environment improvement of traditional korean village based on the development for the restoration of cultural properties to its original state.

  • In order to study the characteristics of vegetation structure in Gundal mountain, we investigated forest community using belt transect method at 30 sites in Gundal mountain. As the result of important value' calculation on over DBH 2cm, Pinus densiflora (56.8), Quercus mongolica (48.5), Pinus rigida(41.4), Castanea crenata (22.3), Quercus variabilis (22.3), Carpinus laxiflora (16.9), Quercus aliena (11.3), Sorbus alnifolia (8.6), and Quercus acutissima (8.5) were in the order of important value. According to the ordination analysis of Gundal mountain forest, Quercus mongolica was found in north face and high of mountain. Carpinus laxiflora was found in north face steep slope and middle of mountain. As DBH analysis, the study community will be dominated by Quercus species. The correlation between the forest community and environment factor could be thought as distinction by soil nutrition etc., but we need more study about environment factors.

  • These days, one of the issues well discussed is the obstruction or screen of sight to mountain-skyline by buildings. So question is to which heights buildings should be constructed over mountain-skyline and then harmony can be realized between mountain-skyline and building-outline. Based on the mentioned above, this study intends to find out the proper projection- level of buildings over background mountain-skyline when considering the types of mountain-skyline, building-outline and building-layout. The results of this study are first, the proper projection-ratio of buildings over background mountain-skyline can be 0.1 because assessment values on harmony-level are more than 3.0 in almost cases, second, the building-outline influences on the assessment values of harmony-level when the types of mountain-skyline are formed left-high & right-low and right-high & left-low, third, building-layout doesn't influence on the assessment va lues of harmony-level, finally, statistically difference doesn't exist between expert group and non-expert group in the assessment values of harmony-level.

  • This study aimed to analyze characteristics of the seasonal habitat use of reintroduced Long-tailed Gorals (n=7) in Woraksan (mountain) National Park. We collected 10,721 goral coordinates in Woraksan (mountain) National Park via transmitters, and analyzed habitat use (e.g., aspect, distance from stream and road) from November 2006 to January 2013. Aspect use was southwest (22.6 %), and seasonal aspect use had a southwestern slope (in the spring, summer, and autumn). A northwestern aspect was detected in winter, but slope of $30^{\circ}{\sim}35^{\circ}$ (19.0 %) was used regardless of the season and mean elevation use was 500 m. Moreover, seasonal use was higher in the summer and lower in the winter and spring. The distance from the stream was mainly 50 m in 17.2 %, except in the winter (distance of 300 m), and it was within 50 m in the spring, summer, and autumn. The distance from the road was 100 m in 25.7 %, and seasonal use was within 100 m except for the winter. Thus, we examined significant differences in the habitat use of reintroduced gorals in Woraksan (mountain), and provide elementary data for habitat stabilization of Woraksan (mountain) National Park where goral restoration has advanced.

  • Mountain streams, which are major components of an entire river network, play an important role as the source of water, sediment, coarse and fine organic matter, and nutrients for lowland rivers. Therefore, dynamics and downstream linkages of each compartment of the mountain stream can be essential for watershed management in catchment scale. The dynamics and downstream linkages are understood as a development of step-pool sequences along a river course. Recently, stream restoration after flooding event often employ the development of step-pool sequences in the world. In this paper, we 1) examined the geomorphic characteristics and the role of step-pool sequences in steep mountain streams by reviewing the results of past studies, and 2) introduced the case studies of stream restoration using step-pool sequences, and finally 3) addressed design methods considering geometry and stability of artificial step-pool sequences for stream restoration. Step-pool sequences play an important role not only as roughness with energy dissipation but also as heterogeneity of stream feature for aquatic habitat. Step-pool sequences, even if they are constructed artificially along a stream, may be effective for small stream restoration considering eco-friendly torrent controls. So far the artificial step-pool sequences were employed for mountainous streams, but those would be applied to urban stream.
