  • 소백산 도솔봉지역을 중심으로 분포하고 있는 천연림의 생육현황과 구조를 정확히 파악하고자. 도솔봉지역에 20개의 방형구(20$\times$20m)를 설치하여 식생을 조사하였다. Cluster분석한 결과 세 개의 집단으로 분류되었다. 수종간의 상관관계는 당단풍과 피나무 및 병꽃나무, 개암나무와 국수나무, 싸리와 쪽동백 등의 수종들 간에는 비교적 높은 정의 상관관계를, 철쭉과 노린재 및 까치박달 등의 수종들 간에는 높은 부의 상관관계를 보였다. 본 조사지의 종다양도는 2.2521-2.3772로 비교적 높게 나타났다. 본 조사지의 왜솜다리군락은 잘 보존해야 할 것으로 판단된다.

  • 상록활엽수림의 식생구조 변화를 모니터링 하기 위하여 완도수목원에 20개의 고정시험구를 1996년에 설치했다. 20개의 고정시험구는 10개의 시험구와 대조구로 구분했으며, 시험구는 적정밀도로 택벌한 후 상록활엽수를 식재했다. 시험처리전 20개 고정시험구의 식생구조는 붉가시나무, 붉가시나무와 개서어나무, 소나무 등이 우점하였고, 소나무군락과 낙엽활엽수군락에서 붉가시나무군락으로 천이되는 식생구조를 나타냈다. 시험처리시험구는 붉가시나무와 소나무가 우점하는 식생구조로 바뀌었고, 관목층과 지피층의 출현종수, 개체수, 피도 등이 증가하였다.

  • 월출산국립공원 금생골의 식생구조 분석을 실시하기 위해 30개 조사구를 설치하고, 식생조사를 실시하였다. Classification 기법 중 하나인 TWINSPAN을 이용하여 군락분리를 시도한 결과, 굴참나무군락(I),상수리나무군락(II), 소나무군락(III), 소나무-상수리나무군락(IV)의 4개 군락으로 분리되었다. 이상의 분석결과 월출산국립공원 금생골의 식생은 군락 I 과 II의 경우 소나무에서 굴참나무와 상수리나무 등 참나무류로 천이가 진행된 발전단계였으며, 군락 III과 IV는 소나무가 참나무류와 경쟁관계에 있는 것으로 판단된다.

  • Correlation between community structure of herbivore and succession of macro-algal flora was examined in subtidal area of Dang-Sa Province, eastern coast of Korea from April 2008 to December 2009. For examination, the authors hypothesized that there are significant correlation between the foregoing two variables. Samplings were conducted every two months quantitatively with SCUBA diving at -3, -6 and -10 depth in the two line transects (barren and forest grounds). As results, rhodophyts was predominated in the algal flora based on the number of species and biomass; molluscs was predominated in the herbivores based on the number of species and echinoderms was predominated in that based on the biomass. There was no significant correlation between the foregoing two variables in the whole survey area and barren/forest grounds. Consequently, the hypothesis was rejected. The authors proposed that examination of correlation between the foregoing two variables should focus on the specific herbivore group(s) (e.g., amphipods) afterward.

  • Background: Artificial light at night has recently been identified as a major factor adversely affecting global insect diversity. Here, we compared the insect diversity in Gwangneung Forest Biosphere Reserve, specifically in the Korea National Arboretum (with no artificial light at night), with that of three nearby urban sites with a gradient of artificial light at night (five locations at each site). We analyzed the effects of the artificial night lighting index, mean annual temperature, and field light intensity (lux) at night on the insect community structure. Results: The urban sites generally exhibited higher species richness and abundance as well as clear indicator species compared with the control site. The size distribution of the collected insects markedly differed between the control and the three urban sites. The abundance of herbivorous and omnivorous insects increased and decreased, respectively, with the increase in light intensity. Species richness of herbivorous and omnivorous insects was likely correlated with the field light intensity at night and artificial night lighting index, respectively. Conclusions: This study demonstrates the association between nighttime environment and marked changes in insect community structure and revealed consequent transition of ecosystem services by changes in trophic group composition.

  • This study was conducted to reveal tree species preference and inter-specific difference of foraging behavior among four canopy-dwelling birds at forest dominated by Quercus mongolica, Acer pseudosieboldian and Carpinus cordata at 1,000 meters above sea level during breeding season of birds from 1995 to 1997 in Mt. Jumbongsan. Breeding birds were about 25 species and dominant birds were Erithacus cyane, Parus ater and Parus palustris. A relatively high number of bush-nesters can be a characteristic of breeding bird community at study area. Three gleaners (Tits, P. varius, P. palustris and P. ater) selectively preferred the trees irrespective of dominant tree species, whereas bark foragers (Nuthatch, Sitta europaea) utilized the dominant trees. The four birds showed significant inter-specific difference in use of foraging location, but the three tits did not show significant inter-specific difference in use of foraging maneuver and trees. Closely related tits may coexist with each other by inter-specific different use of foraging location determined by foliage structure and leaf arrangement.

  • In order to estimate effects of air pollution for pinus thunbergii forests arounding onsan industrial complex, structure of forest vegrtation was surveyed. In the survey of forest vegetation, pinus densiflora have been died or being withered, and importance value(I.V) of rhododendron mucromulatum and lespedeza spp. were low at the vicinity of industrial complex. Especially lespedeza maximowiczii and l. maritima were not entirely appeared at the vicinity of industrial complex. I.V. of quercus serrata, robinia pseudoacacia and alnus firma were preferably high at the vicinity of industrial complex, and those of smilax china, rubus crataegifolius and rhus trichocarpa were similar at every site and it could be guessed that those had a tolerance. Number of species had a difference over 10 species at the vicinity of industrial complex as compared with those of remote sites, and species diversity showed highly at the farther sites of industrial complex, and also at the low layer, number of species, species diversity and evennes were low at the vicinity of industrialcomplex and species weakened to air pollution were disappearing. It was possible that forest vegetation would be changed from pinus spp. to community of a. firma and r. pseudoacacia.

  • 본 연구는 덕유산 국립공원 설천지구내에 건설되고 있는 무주리조트 골프장예정지의 식물군집구조를 밝히고 환경영향평가서의 식물생태계부분 재평가를 위해 실시하였다. 현존식생은 소나무-신갈나무-졸참나무군집이 33.2%, 참나무류군집이 27.3%, 소나무군집이 20.7%, 고산습지가 4.9%이었으며 본 조사지 삼림은 독특한 환경조건을 이루고 있었다. 녹지 자연도는 등급 8, 9가 전체의 93%를 차지하는 안정된 생태계를 구성하고 있었으며 환경영향평가서상의 녹지자연도등급 산정과 본 조사결과와는 많은 차이를 보였다. 54개 조사구에 대한 DCA 분석에서 분리된 군집은 6개로써 소나무군집, 소나무-신갈나무군집, 소나무-졸참나무-들메나무-물박달나무군집, 신갈나무-졸참나무-소나무군집, 신갈나무-굴참나무군집, 버드나무-물박달나무군집이었고 소나무군집을 제외한 기타의 군집은 소나무$\longrightarrow$참나무류로의 생태적 천이단계에 있는 것으로 예측되었다.

  • The purpose of this study is to investigate and analyze a conservation state and a sustainable use of coastal wetland in Sindu-ri Tae-an, using the plant community structure analysis and the awareness result of local residents by published paper. To investigate a forest structure in Sindu-ri area, twenty plots were set up and surveyed. The community, is divided by three groups. The divided groups are Robinia pseudoacacia(I), Pinus thunbergii-Robinia pseudoacacia(II), Robinia pseudoacacia(III). Survey site I is simple canopy layer and deteriorative forest. Survey site II is grassland and swamp, where Pinus thunbergii-Robinia pseudoacacia is dominant trees of vegetation. Robinia pseudoacacia is competition species with Pinus thunbergii in survey site II. Survey site III is barren land(sand-hill) where main species is Robinia pseudoacacia. As a result, survey II district is considered as the most suitable for the conservation of species diversity. It is proposed in this paper that the ecological nature trail would be connected in survey site I and II for environmental education. The local residents of Tae-an, where natural environment is well-conserved, prefer conservation to development of the region. In case of Tae-an, where the condition of the natural environment is well conserved and the development potential exists, the development is in harmony with the environmental education program.

  • 경주 황성공원의 식생구조를 파악하여 생태적 가치를 알아보고, 바람직한 관리방안을 제시하기 위하여 공원 내에 $10m{\times}10m$의 조사구 20개를 설치하고, 군집구조조사를 실시하였다. 군집을 분리하기 위하여 TWINSPAN과 DCA를 이용하였으며, DCA분석결과 소나무군집(A), 소나무군집(B), 참나무류-소나무군집, 아까시나무군집, 그리고 신갈나무군집의 5개로 분리되었다. 종다양도 분석에서 20개 조사구에 걸쳐 목본수종이 총29종 출현하였으나 종조성은 단순하게 나타났다. 각 조사구당 평균출현종수는 $5.32{\pm}2.9$종이었고, 흉고직 경급별 분석에서 소나무는 주로 DBH 27~47cm계급에 분포하였다. 연륜 및 생장분석결과 역사적, 생태적으로 가치가 있는 소나무림이 최근 들어 생장이 둔화되고 있었다. 이상의 조사결과를 바탕으로 관리제언이 제시되었다.
