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.

우리나라는 국토의 60% 이상이 산지로 구성되어 있다. 현재 국내에서는 홍수유출 해석 시 집중형 모형을 주로 이용하고 있다. 집중형 모형은 대개 유역 최하류 지점의 유출구를 기준으로 홍수유출 해석 모형의 매개변수 추정 및 검증이 이루어지며, 유역의 매개변수를 소유역별로 동일하게 가정하여 입력 자료를 구성한다. 따라서 산지하천 유역의 홍수유출 해석 및 예측 시 경사가 급하고 고도가 높으며 집중시간이 빠른 산지하천의 지형적 요소 및 특징을 적절히 고려하지 못하여 정확한 예측 및 해석을 하는데 어려움이 발생한다. 분포형 모형은 하나의 유출구가 아닌 임의의 지점에서 홍수유출 해석이 가능하며, 강우자료 입력 시 유역 평균강우가 아닌 분포형 강우, 즉 역거리자승법, 크리깅 기법 등을 사용하여 분포형 강우로 변환한 지점강우와 레이더 강우를 사용하여 보다 정확한 홍수유출 해석이 가능하다. 그리고 분포형 모형은 입력하는 모든 매개변수를 지형 자료에서 추출하여 사용하기 때문에 인공적인 해석을 배제할 수 있어 인위적인 오차를 줄일 수 있다. 본 연구에서는 평창강 상류유역을 시험유역으로 선정하여 연구를 수행하였으며, 분포형 모형의 하나인 $Vflo^{TM}$를 사용하여 홍수유출해석을 수행하였다. 지형자료만을 사용하여 특정 지점이 아닌 유역 내 임의 지점의 홍수유출량과 집중시간, 홍수위를 산정할 수 있어 산지하천에서 돌발적으로 발생하는 홍수를 신속하게 예측할 수 있었다. 또한 임의의 지점에서의 설계홍수량을 손쉽게 산정하여 수공구조물 설계 시 이용할 수 있으므로 홍수에 의한 인적 물적 피해를 최소할 할 수 있을 것으로 기대된다.

In this paper Gumho drainage basin is divided into six geomorphic units (Bohyeon, Palgong, Biseul mountainous areas and Yeongcheon, Gyeongsan, Daegu basin), and physical geographical background and distributional characteristics of geotourism resources in each geomorphic unit are examined. Most(32 sites, 78%) of geotourism resources in Gumho basin reflect geomorphological environment, rest(7 sites, 17%) of them reflect geological environment. There are three geomorphological resources in Bohyeon mountainous areas, eight geomorphological resources in Palgong mountainous areas, and five geomorphological resources and one cultural resource in Biseul mountainous areas. There are two geomorphological resources, one geological resource, one biological resource, and two cultural resources in Yeongcheon basin. Among them one biological resource and and one cultural resource reflect local geomorphological environment. In Gyeongsan basin are there one geomorphological resource, three geological resources, and one biological resource, but one biological resource reflects local geomorphological environment. There are eight geomorphological resources, two geological resources, and three biological resources in Daegu basin. But two biological resources among them reflect local geomorphological environment.

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.

Weight of evidence model was applied for potential mapping of mountainous wetland to reduce the range of the field survey and to increase the efficiency of operations because the surveys of mountainous wetland need a lot of time and money owing to inaccessibility and extensiveness. The relationship between mountainous wetland location and related factors is expressed as a probability by Weight of evidence model. For this, the spatial database consist of slope map, curvature map, vegetation index map, wetness index map, soil drainage rating map was constructed in Yeongnam area, Korea, and weights of evidence based on the relationship between mountainous wetland location and each factor rating were calculated. As a result of correlation analysis between mountainous wetland location and each factors rating using likelihood ratio values, the probability of mountainous wetlands were increased at condition of lower slope, lower curvature, lower vegetation index value, lower wetness value, moderate soil drainage rating. Mountainous Wetland Potential Index(MWPI) was calculated by summation of the likelihood ratio and mountainous wetland potential map was constucted from GIS integration. The mountain wetland potential map was verified by comparison with the known mountainous wetland locations. The result showed the 75.48% in prediction accuracy.

Forest vegetation of Noinbong (1,338 m) in Odaesan National Park is classified into mountain forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, mountain valley forest, coniferous forest, subalpine coniferous forest, subalpine deciduous forest, shrub forest, riparian forest, afforestation and other vegetation. Including 196 communities of mountain forest vegetation and 7 communities of other vegetation, the total of 203 communities were researched; mountain forest vegetation classified by physiognomy classification are 62 communities deciduous broad-leaved forest, 85 communities of mountain valley forest, 18 communities of coniferous forests, 3 communities of subalpine coniferous forests, 4 communities of subapine deciduous forests, 2 communities of shrub forests, 1 communities of riparian forests, 21 afforestation and 7 other vegetation. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus serrata, Quercus variabilis communities account for 54.856 percent of deciduous broad-leaved forest, Fraxinus mandshurica - Cornus controversa community takes up 15.482 percent of mountain valley forest, Pinus densiflora community holds 78.091 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Pinus densiflora, Tilia amurensis, Fraxinus mandshurica, Cornus controversa, Quercus serrata, and Quercus variabilis are distributed as dominant species of the uppermost part in a forest vegetation region in Odaesan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica which are climax species in the area.

Forest vegetation of Hyangjeokbong (1,614 m) in Deogyusan National Park is classified into mountain forest vegetation and flatland forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, valley forest, coniferous forest, subalpine coniferous forest, shrub forest, grassland forest, afforestation and etc., while riparian forest was found under the category of flatland forest vegetation. Including 122 communities of mountain forest vegetation and 2 communities of riparian forest, the total of 124 communities were researched; the distributed colonies classified by physiognomy classification are 42 communities deciduous broad-leaved forest, 37 communities of valley forest, 8 communities of coniferous forests, 6 communities of subalpine coniferous forest, 3 communities of shrub forest, 1 communities of grassland forest, 21 afforestation and 4 other communities. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus serrata, Quercus variabilis communities account for 47.02 percent of deciduous broad-leaved forest, Fraxinus mandshurica community takes up 57.48 percent of mountain valley forest, Pinus densiflora community holds 77.53 percent of mountain coniferous forest holds, and Taxus cuspidate-Abies koreana community takes up about 50 percent of subalpine coniferous forest. Mountain shrub forest and mountain grassland forest vegetation are concentrated mainly on the top of Hyangjeokbong and the ridge connecting the top and Jungbong. Meanwhile, riparian forest vegetation comprises 0.024% of the whole vegetation area in a study area. In conclusion, minority species consisting of Quercus mongolica, Quercus serrata, Quercus variabilis, Fraxinus mandshurica, Cornus controversa, Pinus densiflora, Abies koreana and Taxus cuspidata are distributed as dominant species of the uppermost part in a forest vegetation region in Deogyusan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica which are climax species in the area. However, in respect of subalpine coniferous forest, the distribution rate of deciduous broad-leaved forest seems to increase gradually due to global warming and artificial disturbance.

We conducted this study to derive the site index, which is a criterion for the planting of Robinia pseudoacacia, a honey plant, and to investigate the diameter distribution change by derived site index. We applied the Chapman-Richards equation model to estimate the site index of the Robinia pseudoacacia stand. The site index was distributed within the range of 16-22 when the base age was 30 years. The fitness index of the site index estimation model was low, but we judged that there was no problem in the application because the residual distribution of the equation had not shifted to one side. We used the Weibull diameter distribution function to determine the diameter distribution of the Robinia pseudoacacia stand by site index. We used the mean diameter and the dominant tree height as independent variables to present the diameter distribution, and our analysis procedure was to estimate and recover the parameters of the Weibull diameter distribution function. We used the mean diameter and the dominant tree height of the Robinia pseudoacacia stand to show distribution by diameter class, and the fitness index for dbh distribution estimation was about 80.5%. As a result of schematizing the diameter distribution by site indices as a 30-year-old, we found that the higher the site index, the more the curve of the diameter distribution moved to the right. This suggests that if the plantation were to be established in a high site index stand, considering the suitable trees on the site, the growth of Robinia pseudoacacia woul d become active, and not onl y the production of wood but al so the production of honey would increase. We therefore anticipate that the site index classification table and curve of this Robinia pseudoacacia stand will become the standard for decision making in the plantation and management of this tree.
