  • 한반도의 약 70% 이상을 차지하고 있는 산지는 많은 산들과 산맥으로 이루어져 있으며, 산맥들은 대기환경에 큰 영향을 준다. 산맥의 분류조사는 1900-1902년 일본학자에 의거 수행 된 후, 현재 산맥의 이름이 매우 많고 혼선이 되고 있다. 본 연구는 기존의 산맥 이름과 그 분류를 간단히 하여 사회적 교육적 활용에 가치를 두고 있다. 먼저, 중국의 만주로부터 (대)한반도까지 주축을 이루는 세계적인 제2차 중규모산맥을 단일 이름인 고려산맥으로 명명하였다. 그리고, 고려산맥에 수반되는 지역적인 제3차 산맥들은 지린(길림)산맥, 함경산맥, 태백산맥, 소백산맥으로 분류하고, 그 다음 제4차 산맥은 랴오닝산맥, 옌볜(연변)산맥, 함북산맥, 평북산맥, 황해산맥, 차령산맥, 경상산맥, 남해산맥 등 8개의 중소 산맥으로 분류 하였다. 일반적으로 한반도의 산맥들은 지구규모 대순환의 영향을 지속적으로 받고 있다. 산맥의 풍상과 풍하 측에서 발생하는 공기환경적인 변화에 따라, 인간과 생태계에 주는 대기환경의 영향평가와 그 감시의 필요성을 강조하였다.

  • The Weather Research and Forecasting (WRF) model was designed to identify the role of the Taebaek Mountains in the occurrence of heavy snowfall in Yeongdong area with a strong northeast wind on January 20-21, 2008. To this end, in addition to the control simulation with the realistic distribution of the Taebaek Mountains, a sensitivity experiment that removed the orography over the Taebaek Mountains was performed. The control simulation results showed that the resulting wind field and precipitation distribution were similar to what were observed. Results from the sensitivity experiment clearly demonstrates the presence of orographic lifting on the windward slope of the mountains. It is concluded that the altitude of the Taebaek Mountains is the main controlling factor in determining the distribution and amount of precipitation in the Yeongdong area for the case of heavy snowfall in January 2008.

  • Mountains have been playing an important role in the Japanese culture. It is important from landscape planning perspectives to maintain mountains in the proximity of cities. In this thesis, the geographical perception of residents in Kohoku New Town has been studied. Geographical changes before and after the Kohoku New Town development were clarified first. Following these clarifications, interviews with residents who moved into the area before and after the development were conducted. In this investigation, the interviewees were asked about mountains, valleys, hills, and slopes; and the areas that they recognize on the map were then specified. From these results, the mountain area which residents recognize and the actual geographical features were compared. The geographical characteristics of the mountains that the residents recognize were revealed, and the perception of mountains was defined. Not only did geographical features and vegetation affect the perception of mountains, but also residents' personal experiences were important. As a result, new information for future geographical landscape planning has been obtained.

  • 실험지역으로 선정된 거제도와 남해도에 대해 Yamada(1999)의 산치차수구분을 시도해 보았으며, 그 결과를 바탕으로 산지차수구분을 남한 전 지역에 확대·적용하였다. 남한 지역의 최고 산지차수는 5차수였는데, 설악·태백산지, 지리·덕유산지, 영남알프스산지 모두 3곳으로 확인되었다. 4차수 산지는 10곳, 3차수 산지는 87곳에 나타난다. 5차수 산지는 대략 한반도의 융기축과 관련이 있는 것으로 판단되며, 4차수와 3차수 산지의 분포는 2차산맥과 같은 북동-남서의 방향성을 지니고 있다. 한편 하천차수법칙과 마찬가지로 차수별 산지 개수, 면적, 비고의 로그함수 값이 차수에 대해 선형관계를 이루고 있다. 차수별로 구분된 산지 중에서 기존의 산맥체계에서 고려하지 않은 산체들을 확인할 수 있었는데, 이들은 한반도의 지체구조를 보다 자세하게 이해하는 근거로 활용될 수 있다. 국립공원 및 도립공원은 대부분 5, 4, 3차수 산지에 분포하고 있다. 특히 속리산국립공원이 남한 지역의 대표적인 두 산체인 지리·덕유산지와 설악·태백산지를 연결하는 생태축의 중요한 연결고리 역할을 하고 있음을 확인할 수 있었다. 이는 산치차수구분법이 지니고 있는 지형학적 의미뿐만 아니라 실용적 가치를 시사해준다.

  • The altitude criteria of 'Management of Mountains District Act' and 'National Land Planning and Utilization Act' are different because the adaptive reuse permissions on mountains district by two acts have been operated individually and each criteria has some problems for application. This study aims to suggest proposals for improvements of altitude criteria by two acts. The altitude criteria of the duel legal systems were researched by literature review and inherent issues were derived by interview with public officers and GIS tools applied to cases. The results are as follows : First, duel criteria systems need to be integrated based on the format by 'Management of Mountains District Act'. Second, the criteria index(50/100) by 'Management of Mountains District Act' need to be adjusted due to the preserved area ratio in mountains district and the each definition of 'the peak point of the mountain' and 'the tail of the mountain' can be changed as 'the highest point within the same slope(including ridge)' and as 'the average of the highest and the lowest point on boundary between the mountain district and the other land use district'. Third, the method of slope division may be determined by the conditions of local areas and the discrepancy between the two slopes in common boundaries must be adjusted. Finally, the maps containing preservation areas and development areas need to be notified.

  • This study analyzes the spatial distribution of the highest level terrace which can be regarded as an initial land surface before the uplift of the Taebaek Mountains and estimates spatial characteristics of the incision and uplift rates around the Mountains. The altitude above the riverbed of the 54 highest level terraces seems to be greatly influenced by the incision of large stream and their elevation shows a high correlation with the uplift of the Mountains. The elevation of the terraces in the north and middle parts decreases westward with a rate of 5~6 m/km and meets with the sea level at area 100~120 km apart from the Mountains. Therefore, it can be suggested that the west coast of Korea might have generally experienced subsidence during the Quaternary. The elevation of the terraces suggests that area with a direction of N-S or NNW-SSE from Yeoryang-myeon, Jeongseon-gun to Taebaek-si shows the highest uplift rate around the Mountains and area with a direction of N-S connecting Girin-myeon, Inje-gun and Pyeongchang-eup, Pyeongchang-gun also indicates a high uplift rate.

  • This study tries to analyze topographic distribution and characteristics of as well as formative age and incision rate of fluvial terraces in Danyang River on western side and Geum River on eastern side of the northern Sobaek Mountains and to estimate geomorphic development during the late Quaternary in the mountains regarded as one of the uplift axes in the Korean Peninsula. OSL age dating shows that the fluvial terrace I with an altitude above riverbed of approximately 7~13 m in Danyang River has a formative age of approximately 18 ka (MIS 2) and incision rate in the river is approximately 0.156~0.194 m/ka based on the age. Altitudes above riverbed of the fluvial terrace I in Geum River range from approximately 7 to 14 m and the terrace is thought to be older than 70 ka based on age result from aeolian sediments above the terrace deposits, suggestive of an incision rate less than approximately 0.10 m/ka. These results indicate lower uplift rate in the northern Sobaek Mountains than in the Taebaek Mountains. Moreover, it can be suggested that the northern Sobaek Mountains has experienced asymmetric uplift during the late Quaternary, because the river on western side of the northern Sobaek Mountains shows greater uplift rate than the eastern side river does. Low incision rate in Geum River can be attributed to low altitude of the river basin with little difference in altitude from the base level as well as to gentle river slope due to influence of Nakdong River.

  • The main purpose of this study was to develop Mountain Search and Rescue System for enhancing search and rescue operations in the mountains. This study also focused on presenting an alternative to using a cellular phone for requesting rescue due to their unreliability in remote areas. This system is designed to help in the search and rescue of people in emergency situations in the mountains. It is composed of buzzer sensors, environmental information sensors, and a statistical analysis program. A key feature of this system is that it does not require an infrastructure of internet or CDMA networks for its operation in the mountains. The measure for the study was conducted by using a zigbee protocol analyzer, RF module and 433MHz Helical antenna to analyze the rate of data reception in relation to the distance between nodes. This system is applicable to mountains provided the distance between nodes is over 100 m and under 150 m.

  • Rural people of Sudan are endowed with a deep knowledge concerning the utilization of different tree species. However research on the local knowledge related to tree species utilization still lacks adequate attention. The study objectives were to identify the existing local knowledge related to the utilization of the tree species and the existing threats to the availability of the trees. A total of 300 respondents were selected randomly from Rashad district in Nuba Mountains in 2011. Semi-structured interview, direct observation, group discussion, preference ranking and direct matrix ranking were used to collect the data. The study results revealed that people of Nuba Mountains utilize different tree species for food, medicinal purposes, fodder, firewood, construction and cultural ceremonies. The study results also indicated that the availability of trees is negatively influenced by firewood collection, agricultural expansion, drought, overgrazing and charcoal production. The study concluded that local knowledge has crucial role in tree species utilization in Nuba Mountains. Further researches to document and substantiate the local knowledge on useful tree species are highly recommended.
