The potential natural vegetation of Naejangsan national park area, southwestern Korea, was inferred from the actual vegetation. With the phytosociological classification, ordinatins and field surveys, the actual vegetation map of the area was made in scale 1:25, 000, including ten communities of Pinus densiflora, quercus mongolica, Quercus variabilis, Carpinus laxiflora, Daphnipyllum macropodum, Carpinus tschonoskii, Quercus aliena-Carpinus tschonoskii, Cornus controversa-Lindera erythrocarpa, Torreya mucifera-Zelkova serrate and Acer mono-Zelkova serrata community. The analyses of species richness, age structure and various informations on vegetation changes suggest the three pathways of late stage succession from P. densiflora forest to climatic climax. The first of them is through Q. variabilis forest to Q. monogolica forest in the upper parts of the mountain, the second through Q. variabilis and Q. serrata forest to C. laxiflora forest in the middle parts and the third through Q. aliena forest to C. tschonoskii forest in lower parts. Considering the actual vegetation and informations on the vegetation changes including human activities, the potential natural vegetation of the mountain mainly composed of Q. monogolica, C. laxiflora, C. tschonoskii, P. densiflora and Z. serrata forest as climatic climax and/or edaphic climax was inferred. The present situration of nature conservation in the area was estimated by the examination on the actual vegetation and potential natural vegetation map.

The purpose of this study was to analyze the impact of greenhouse cultivation area and groundwater level changes due to the water curtain cultivation in the greenhouse complexes, which are mainly situated along rivers where water resources are easy to secure. The groundwater observation network in Miryang, Gyeongsangnam-do, located downstream of the Nakdong River, was selected for the study area. We classified the groundwater monitoring well into the greenhouse (riverside) and field cultivation areas (plain and mountain) to compare the groundwater impact of water curtain cultivation in the greenhouse complex. The characteristics of groundwater level changes classified by terrain type were analyzed using the observed data. Riverside wells have significant permeability coefficients and are close to rivers, so they are greatly affected by river flow and precipitation changes so that water level shows a specific pattern of annual changes. Most plain wells do not show a constant annual change, but observation wells near small rivers and small-scale greenhouse cultivation areas sometimes show annual and daily changes in which the water level drops during winter. Compared to other observation wells, mountain wells do not show significant yearly changes in water level and show general characteristics of bedrock aquifer well with a low permeability coefficient.

Field measurement of wind characteristics is of great significance for the wind engineering community. High-frequency anemometers such as ultrasonic anemometers are widely used to obtain the high-frequency fluctuating wind speed time history. However, conventional instrumentation systems may suffer from low efficiency, non-real time transmission and higher maintenance cost, and thus are not very appropriate in the field measurement of strong winds in remote areas such as mountain valleys. In order to improve the field measurement performance in those remote areas, a wireless high-frequency anemometer instrumentation system for field measurement has been developed. In this paper, the architecture of the proposed instrumentation system, and measured data transmission and treatment will be presented firstly. Then a comparison among existing instrumentation systems and the proposed one is made. It shows that the newly-developed system has considerable advantages. Furthermore, the application of this system to the bridge site located in the mountain valley is discussed. Finally, typical samples of measured data from this area are presented. It can be expected that the proposed system has a great application potential in the wind field measurement for remote areas such as the mountainous or island or coastal area, and hazardous structures such as ultra-voltage transmission tower, due to its real-time transmission, low cost and no manual collection of data and convenience.

This study comprehends that the landscape of Ipsan Village is the accumulated output of the landscape management and social behavior by the historic personages through the reference research and field surveys. And the study sorted out the over-layered landscape characteristics of Ipsan Village by analyzing the dispersed landscape elements as follows. First, right before the start of Japanese invasions to Korea(1592-98), Tamjin(耽津) An(安) Family moved into Ipsan and started establishing the a single clan village. At a site with mountain background and facing the water(背山臨水), the village used to be a typical farming one with an organically planned road-system and housing area following the traditional order. However, the landscape has changed drastically since the 20th century with the construction of banks, roads and readjustment of arable land etc. Second, the original landscape, which can be figured out through the 'Gosanjaesibyukgyeong(高山齋十六景)' in the 18th century, shows its harmony with natural landscape: mountain & valley, stream & field, traditional trees, etc, cultural landscape: village, well, spring, etc, and momentary landscape: seasons, time, weather phenomena, sound, behavior, etc. Third, based on the second, 16 natural landscape elements: mountain & stream, planting, etc. and 25 cultural landscape elements: housing spaces, self-cultivation & ceremony spaces, community spaces and modern education & enlightenment spaces were selected and interpreted as landscaping meanings. Fourth, the over-layered landscape which stems from the compositive functions and inter-connectivity of landscape elements which consists Ipsan Village is regarded as 'Natural geographical and Fungsu landscape', 'Rural production and livelihood landscape', 'Confucian ceremony and symbolic landscape' and 'Modern education and enlightenment landscape.'

For the first time basic settlement area development plan was established in 2010, in order to promote cooperative coexisting development among regions, as time that regional competitiveness determines national competitiveness started. Basic settlement area development plan is composed of 7 sectors and 24 general subsidy projects. It was judged that experience and tourism business as the center is required to be analyzed, which may have effect on activation of farm village, fishing village and mountain village, and inflow of city people, in agriculture, forestry and fishery sector in order that added value of agriculture and fishery is increased, and tangible and intangible resources are applied, and pure agriculture, forestry and fishery is developed. And currently farm village, mountain village and fishing village of our country faces desperate crisis situation that they cannot help groping for substitutive to create new revenue model, and agriculture and fishery of primary industry has limit of increasing income of farmer and fisherman. Agriculture, forestry and fishery experience and tourism business was classified by types, and then standard of 12 categories and 48 sections was prepared, for searching method to supplement and develop it. Trend of experience and tourism business was understood, and problem was found, and then it may be used as indicator material to carry out creative and differentiated business plan establishment and business operation, and may be opportunity to reject overlapped business among regions, and to promote balanced regional development.

1968년 프랑스에서 출현하여 전 세계로 널리 확산된 생태박물관은 유물의 소장 전시보다 어떤 지역의 자연 문화유산 전체를 '본래의 장소에서' 보존 해석하여 그 지역의 장소적 의미를 찾고 주민의 참여와 지역 공동체의 발전을 도모하는 것을 목적으로 하는 새로운 유형의 박물관이다. 이 박물관이 갖는 의의는 사라져가는 지역의 집단 기억을 회복하여 주민의 문화적 정체성을 되찾고 낙후된 지역을 활성화하는 데 있다. 그런데 이 박물관은 분산형 야외박물관인 경우가 많기 때문에 흩어져있는 지역 유산 전반에 대한 원격 정보 제공과 종합적 해석이 가능하도록 유산을 디지털화하여 기록 보존 해석 활용하는 '웹 생태박물관'이 필요하다. 본고에서는 무등산이라는 지역을 예로 들어 웹 생태박물관의 가능성과 그 구성 내용 방법에 대해 고찰하였다. 특히 후자에 대해서는 지역 고유의 주제를 선정하여 관련 유산을 토대로 디지털 아카이브를 구축(기록 보존)하고, 웹 전시를 개최(해석)하고, 전자문화지도를 제작(활용)하는 방안을 제시하였다.

The climate is changing rapidly, and this may pose a major threat to global biodiversity. One of the most distinctive consequences of climate change is the poleward and/or upward shift of species distribution ranges associated with increasing temperatures, resulting in a change of species composition and community structure in the forest ecosystems. The Baekdudaegan mountain range connects most forests from the lowland to the subalpine zone in South Korea and is therefore recognized as one of the most important biodiversity hotspots. This study was conducted to understand the distribution range of vascular plants along elevational gradients through field surveys in the six national parks of the Baekdudaegan mountain range. We identified the upper and lower distribution limits of a total of 873 taxa of vascular plants with 117 families, 418 genera, 793 species, 14 subspecies, 62 varieties, two forms, and two hybrids. A total of 12 conifers were recorded along the elevational gradient. The distribution ranges of Abies koreana, Picea jezoensis, Pinus pumila, and Thuja koraiensis were limited to over 1000 m above sea level. We also identified 21 broad-leaved trees in the subalpine zone. A total of 45 Korean endemic plant species were observed, and of these, 15 taxa (including Aconitum chiisanense and Hanabusaya asiatica) showed a narrow distribution range in the subalpine zone. Our study provides valuable information on the current elevational distribution ranges of vascular plants in the six national parks of South Korea, which could serve as a baseline for vertical shifts under future climate change.

번식기 조류 조사(Breeding Bird surveys)는 생태계 내 군집 구조와 기능 그리고 생물다양성 보전을 위한 중요한 기초 자료를 제공한다. 최근 기후변화 등에 따른 생물다양성이 급변함에 따라 산림성 조류조사 데이터의 정확성 및 공간적인 확대와 시계열적 모니터링을 위해 음향 센서 등의 활용이 요구되고 있다. 본 연구의 목적은 조류 음성을 녹음한 데이터와 현장 조류조사 자료를 비교 분석하여 번식시기 산림성 조류의 군집 다양성 평가에 음향 녹음 센서의 활용 가능성을 파악하는 것이다. 2013년 5월 2일부터 16일까지 현장조사 및 녹음을 실시하였으며, 조사 대상지는 점봉산지역의 곰배령과 조침령, 그리고 소백산지역의 죽령과 고치령 구간으로 총 4개 권역 48개 지역, 186개 지점이었다. 녹음결과를 이용하여 현장조사에 의한 조류군집지수와의 상관관계를 분석한 결과, 녹음에 의한 조류 종의 수와 개체수, 울음소리 횟수는 현장조사에 의한 조류의 종의 수, 개체수와 유의미한 상관관계가 있었지만, 녹음에 의한 조류 종의 수와 음성의 횟수는 현장조사(관측과 청음 병행)에서의 종다양도, 종풍부도와 유의미한 상관관계가 있었지만 종균등도와는 약한 상관관계 혹은 관계가 없음으로 나타났다. 결과적으로 현장에서의 음성녹음 자료를 분석할 경우 조류군집의 종조성과 함께 종다양성을 확인할 수 있었다. 비번식기의 음성녹음에 비하여 번식기의 음성녹음은 녹음결과와 종다양성과의 상관관계에서 보다 신뢰도가 높게 나타났으며 활용가능성이 더 높은 것으로 사료된다.
