Yamada's mountain ordering is to be said as an upward system, because the area and volume of the mountains become the larger as more than two lower order mountains constitute the higher order mountain. However, his mountain ordering shows some limitations to totally understand the mountain systems and to systematically manage the various kinds of mountainous informations. Because the independent third, fourth and so on, as well as the second lower order mountains are included in the higher order mountain. In order to solve the problem above, the downward system is suggested as the alternative of his upward system. The downward system means that the higher order mountain is classified into the second lower order mountains, and the second lower order mountain is classified into the third lower order mountains and finally the 2nd order mountain classified into the 1st order mountains. The method to classify a certain mountain systematically into all mountainous elements and the new nomenclature to be used for the classified elements are developed, using the downward system above. And the structure of database could be also suggested for the integrated and systematic management of mountain informations.

이 글은 상대적으로 연구 성과가 미비하고 그 접근방식도 다양하지 못했던 기존의 산지촌 연구를 회고하면서, 경관생태학적 관점을 활용하여 산지촌의 분포지역을 세분하고 이 틀 속에서 산지촌에 접근하자고 하였다. 특히 산지촌들이 생태지역에 따라 그 존립방식에 있어서 내적 차별성을 보인다는 점을 주목하였다. 연구지역은 산지촌이 전형적으로 분포하고 있는 강원 남부지역의 태백산맥 일대로서 지형경관, 사면경사도, 해발고도 등에 의거하여 세 개의 생태지역으로 세분될 수 있었다. 고위평탄면지역 산지촌, 고위산간지역 산지촌, 그리고 급사면산간지역 산지촌이 그것이다. 이러한 생태지역의 개념에 기초하여 먼저 산지촌의 형성과정을 역사적으로 추적해본 후, 자연경관, 촌락의 분포 패턴, 생활방식 등을 생태지역별로 비교하면서 구체적으로 서술하였다. 이 과정에서 도출된 세 곳의 생태지역, 생태지역별 자연경관 및 생활양식의 차별성, 산지촌 생활의 현실태, 촌락존립상의 문제점 등은 산지촌의 진흥방안을 모색하는 데 매우 중요한 관점과 방향을 제시해 줄 것으로 본다. 따라서 본고에서 사용한 경관생태학적 방법론은 연구지역 이외의 지역에서도 적용될 필요가 있으며, 이러한 연구가 전국의 산지촌으로 확대될 때 현실에 바탕을 둔 산지촌의 진흥방안이 마련될 수 있을 것으로 본다.

산림청은 올해부터 산지에 대한 개발 및 이용규제 등을 대폭 완화한다는 계획이다. 산지 개발 및 이용에 관한 권한을 지방자치단체에 대폭 이양하는 등 산지 규제를 완화해 지자체와 기업, 임업인들에게 도움이 될 수 있도록 하겠다는 것. 이에 대해 그동안 산지를 마음대로 활용할 수 없어 고민하던 임업인과 지자체들은 환영하는 분위기다. 하지만 지금까지 정부가 강력한 산지규제 정책을 시행해왔어도 골프장, 공장 건설 등으로 산지훼손이 심각한 것으로 나타나 이번 산지 규제 완화에 대한 우려의 목소리도 있다. 산지규제 완화 정책과 이에 따른 효과 및 문제점은 무엇인지 살펴본다.

The mountain region in Korea has been known as 70% of total area and most Korean people have recognized Korea as the mountainous country. Those concepts are thought to be mislead by the definition of the Korea Forest Service for the mountain region. According to KFS's definition based on the land-use, the forest and farmland at the low altitude are also included in the mountain region. In this study, firstly, the geomorphological mountain region is extracted according to the definition of Kapos et al. (2000). The rates of mountain region in S. Korea, N. Korea, Korea Peninsular are 31%, 51%, 42% respectively. And the rates between mountain area and non-mountain area in the 300-1000m and 1000-2500m intervals are considerably different due to the existence of plateaus such as high-level plain surfaces. Secondly, using the overlay analysis in GIS, the distribution of mountain areas are compared with that of order-mountains' areas defined by Qui and SON (2010). Even in case of the 5th order, the highest order mountains, the hill & plain and non-mountain areas are included in that mountain area. It is possible to suggest that the definition of the KFS is completely different from the academic, realistic and epistemic definition for mountain area, and the geomorphological definition of mountain area is useful to classify the mountain area according to the its physical properties. Therefore, it would be expected that the definition contributes the development of methodologies on the scientific management of mountain area in future.

Pinus densiflora is a dominant conifer species in Korea and also distributed in regions of Japan and eastern China. Success in the establishment and productivity of forest tree plantation is largely determined by selection of species and seed source. The provenance tests of Pinus densiflora in Korea are underway. However, the information of the growth performance of Japanese and Chinese provenances are insufficient. Therefore, this study was conducted to evaluate the growth performance of Pinus densiflora Japanese provenances. Data were collected from a provenance trial including established by Korea Forest Research Institude at Chungju in 1970. Six Japanese provenances ($31^{\circ}90^{\prime}{\sim}40^{\circ} 27^{\prime}$ in latitude and $128^{\circ}47^{\prime}{\sim}141^{\circ}80^{\prime}$ in longitude) were included in this trial. Pyeongchang provenance at Kangwon province in Korea was used for reference provenance. At nursery stage, the height and diameter at root collar of six Japanese provenances were smaller than those of Pyeongchang provenance. Among Japanese provenances, Kasahara provenance showed higher growth performance than those of others. The provenance rankings of growth performance were fluctuated until age 11. However, the growth performance of Japanese provenances showed higher than those of reference provenance after age 17. Kirishima-yama provenance showed best growth performance. Simple correlation analysis was conducted to investigate the geographic factors affecting growth performance. The height growth showed negative corelation with latitude of seed origin. Generally, Japanese provenences of Pinus densiflora were well adapted and grown in Chungju. However, it was suggested that further studies on other sites need to generalize the results of this study.

산지를 이용하기 위해서는 규제지역 정보, 임상, 지형 등 다양한 정보가 필요하다. 반면에 산주들은 산지 정보를 획득하기가 어렵다. 산지를 개발하고자 토지 매입 등을 거친후 인 허가 과정에서 개발 적지가 아닌 것으로 판명되면서 사회적 비용이 낭비될 우려가 있다. 산림청에서는 이러한 문제점을 해결하고자 대축척의 산지구분도를 구축하여 '09년부터 산지정보시스템으로 서비스하고 있다. 산지관리 업무를 기존의 단 방향적이며 정적인 C/S 기반에서 개방과 참여를 중시하는 웹 2.0 기반으로 개편한 것이다. 산림청에서는 서비스하는 산지 정보 변화 내역 모니터링 등 시스템 유지 관리를 통해 최신 산지 정보를 제공하는 한편 사용자 편의성도 지속적으로 강화할 계획이다.

최근 집중호우나 극한 강우사상으로 인하여 산사태나 토석류와 같은 산지재해가 빈번하게 발생하고 있으며 특히 우리나라는 지형 특성상 주거지역이 산지와 인접해 있는 경우가 많아 재해발생 시 피해를 가중시키는 원인이 되고 있다. 산지재해는 예측하기가 어렵고 산지에서 발생한 토석류가 계곡을 따라 흘러 내려와 도심지 및 산지와 인접한 도로나 주택지에 많은 피해를 발생 시키고 있다. 본 연구에서는 해마다 반복적으로 발생하고 있는 산사태나 토석류와 같은 재해의 피해저감과 원인분석을 위하여 강원도 삼척시 도계읍 일대를 대상지역으로 선정하고 산지유역의 위험성 분석을 위하여 사면안정성 예측 모델인 SINMAP 모형을 사용하여 산지재해가 발생 가능한 위험지역 및 안전한 구간을 분석하고 지형분류기법 중의 하나인 Topographic Position Index(TPI) 분석방법을 통해 대상지역의 지형위치지수를 계산하여 위험지형을 분류하였다.

The purpose of this study was to improve forestland characteristic evaluation system's indicators for rational development and ecosystem conservation. There has been no consideration for statistical duplication between variables, and it caused inefficient data collection. Furthermore, the same evaluation criteria were applied for all forestlands without considering regionally different characteristics, and it made variation for designation cancel rates of preservation semi-preservation forestlands between cities. To solve these problems, we first removed 'DBH' variable which has a multicollinearity. Second, we applied standard normal distribution for each forest watershed type. As a result of eliminating 'DBH', the numbers of parcels for all grades except A were changed but their numbers and areas were not large enough to consider the change of total score. For the output of analyses with the existing same regional criteria, the total scores of urban type and urban-fringe type forestlands were higher than those of other types. The numbers of parcels for A and B were increased and those for C and E were decreased by applying standard normal distribution. This caused the increase of preservation-oriented parcels. Finally, we suggested a new evaluation method based on standard normal distribution to consider regional forest characteristics and to solve regional imbalance.

Approximately 64 percent of Korean territory is covered with mountains, and there is occurred a continuous mountain disaster such as landslide, debris flow and slope failure around mountain slopes due to heavy rainfall and typhoon in the summer season. Even in such a reality, the development of mountain areas is being carried out through the development and expansion of social infrastructures centered on mountain areas, but systematic management is insufficient. Constructions of a forest road facility for mountain slopes can be a cause of mountain disasters intensively in the summer season due to artificially changing the mountain area. In this unstable mountain environment, efforts to build a disaster-resistant environment are urgently needed. This research is to analyze the stability of mountain slopes according to soil depth (1~5 m) and mountain slope ($20{\sim}60^{\circ}$) considering the characteristics of rainfall infiltration under extreme rainfall conditions. As a result, the stability of the mountain slope was found to be different according to the depth of soils and the saturation area of the soil layer. As well as the stability of the mountain area was found to be lower than that of the natural mountain area. Specially, rainfall infiltration occurs at the upper slope of the forest road. For this reason, the runoff phenomenon of rainfall infiltration water occurs clearly when the depth of soil layer is low.

Mountainous areas are 64% in Korea and are allowed to be used by the permission standards of the "Mountainous Districts Management Act". In the act, slope and elevation criteria are defined to regulate the use of vulnerable land parcels to disaster. However, the standards cannot represent topographical variation in a land parcel such as terrain relief. Therefore, the applicability of slope type standard as a permission standard was tested using Catena in this study. Based on the theoretical grounds, two slope types were analyzed as 'risky slope' with disaster risk. The slope types of landslides in Namwon City were analyzed that 'risky slope' types were distributed about 57%. This study analyzed the forestland parcels that could be used when applying the current permission standards and the parcels that were already used in Namwon City. The ratio of the 'risky slope' in the parcels was more than 50%. Therefore, it is necessary to prevent the mountain development in 'risky slope' by establishing permission standard related to slope types. In addition, this study suggested the ratio of 'risky slope' in the parcel for the permission standard for forestland use conversion.
