  • Comparison of oribatid mite community structures among Namsan, Kwangreung, and Mt, Jumbong, which receive different levels of environmental stress from severe to almost none, was made in coniferous and deciduous forests, respectively. The number of species of oribatid mites was significantly lower in Namsan and Mt. Jumbong than in Kwangreung in the coniferous forest (p<0.05). In the deciduous forests, the number of species of oribatid mites was significantly lower in Namsan than in Kwangreung and Mt. Jumbong. Dominant species in 3 regions were remarkably different. Similarity of the oribatid community between Namsan and Kwangreung was much higher (ca. 2 times) than similarities between Namsan and Mt. Jumbong. and Kwangreung and Mt Jumbong. Diversity index (H$^{\prime}$) value of oribatid communities in deciduous forests in Namsan, Kwangreung and Mt. Jumbong was 2.74, 2.78, and 2.87, respectively. Diversity (H$^{\prime}$) value of oribatid communities in coniferous forests in Namsan, Kwangreung and Mt. Jumbong was 2.83, 2.62, and 2.38, respectively. Namsan and Kwangreung were characterized as O-type in both coniferous and deciduous forests On the contrary, Mt. Jumbong was characterized as MG-type in MGP-I analysis.

  • 강원도 양양군과 인제군에 걸쳐 설악산 국립공원의 남부를 차지하고 있는 점봉산게 서식하는 거미류는 미확정 5종을 포함하여 총 27과 88녹 144종으로 나타났다. 풍부한 종 구성을 갖는 우점과의 순위는 접시거미과가 21종 (14.6%), 왕거미과 20종(13.9%), 꼬마거미과 16종(11.1%), 깡충거미과 12종(8.3%)등의 순이었고, 나머지 과는 미소 하였다. 생활형에 따르면 조망성거미는 89종(62.2%)으로 배회성 거미 55종(37.8%)보다 우세하였다. 거미류의 생태적 분포면에서 보면 구북계(Pal. spp.)가 16종 (11.2%), 전북계(Hol. spp.) 7종(4.9%) 범세계종(Cos. spp.)이 1종(0.7%)이고 한국고유종(Kor. spp.)은 25종(미확정 5종 포함, 17.4%)이었고 동양계(Or. spp.)는 한 종도 채집되지 않았다. 따라서 점봉산은 한국고유종이 차지하는 비율이 높아 가장 한국적 특성을 잘 반영하는 동시에 북방계(Pal. + Hol., 16.1%)의 거미가 우세한 지역임을 알 수 있다. 또한, 인접국가와의 공통성을 보면, 한국과 일본, 한국과 중국, 한국과 러시아 (사할린과 시베리아 포함)의 공통종은 각각 115종(80.4%), 98종(68.5%), 48종(33.6%)으로 일본, 중국과 공통성이 매우 크게 나타났으며 한·일·중·러 공통종은 39종 (27.3%)으로 나타났다. 한편, 개발치 정도와 방향에 따른 물리적 환경 변화가 생물상에 영향을 주고 있음을 알 수 있었으며, 따라서 자연환경을 보전을 위해서는 개발의 정도와 시간의 경과에 따른 생물상의 변화를 감지할 수 있는 감시 시스템이 필요할 것으로 사료되며, 거미류는 종다양성과 발생밀도가 자연상태에서 매우 높고 발견이 용이하기 때문에 조사의 진행정도에 따라 환경오염 등의 환경변화를 반영할 수 있는 지표생물로 활용 가능하다고 판단된다.

  • 본 연구는 우리나라 중부지방에 위치한 점봉산과 봉의산에서 일부 자생수목을 대상으로 봄철 식물계절 변화를 관찰 비교하고, 관련 환경인자를 함께 측정하여 미기후 변화에 따른 식물계절 차이를 구명하였다. 점봉산 조사지의 2004년 $1{\sim}5$월 평균 기온은 봉의산 조사지보다 $4.1^{\circ}C$ 더 낮았다. 점봉산 내 조사구별 4월의 토양온도는 남사면에 비해 서사면에서 $1.8^{\circ}C$, 북서사면에서 $4.4^{\circ}C$ 각각 낮았다. 표본목 중 개화시기가 가장 이른 종은 생강나무로 봉의산에서 3월 하순에, 점봉산에서 4월 초순에 각각 개화하였다. 동일 수종의 개화시기는 점봉산보다 봉의산에서, 그리고 서사면이나 북사면보다 남사면에서 더욱 빨랐으며, 이른 봄 개화하는 수종의 경우는 지역간 약 2주의 차이를 나타냈다. 개엽시기는 대개 봉의산에서 4월 중순, 점봉산에서 5월 초순이었으며, 동일 수종의 개엽시기 역시 점봉산보다 봉의산에서 2주정도 빨랐다. 개화 및 개엽시기의 Nuttornson 온량지수(Tn)와 일적산온량지수(YDI)는 동일 수종에서 지역간 유사한 값을 나타냈다. 지역간 식물계절 변화는 주로 온도에 의해 영향을 받는 것으로 분석되며, 기후변화와 온도상승은 식물계절 변화를 현재보다 더욱 촉진시킬 수 있음을 시사한다.

  • Macroinvertebrate contribution to the leaf litter breakdown of Carpinus cordata was estimated at headwater streams at Mt. Jumbong (38°03'N, 128°25'E) during spring and winter spring by using two types of litter bag. Coarse-mesh bags with 10 g of leaf letter were placed in a 1st-order stream in April (the spring experiment) and December 1995 (the winter-spring experiment). Fine-mesh bags with 5 g of leaf letter were placed in a nearby 3ed-order steam. The breakdown of Carpinus in coarse-mesh bags was rapid, and, in terms of season, leaf litter processed rapidly during spring. daily mass loss rates of leaf litter (-k±1 SE) were highest for coarse-mesh bags in the spring experiment (-0.0429±0.0048), followed by coarse-mesh bags in the winter-spring (-0.0146±0.0014), fine-mesh bags in the spring (-0.0078±0.0004), fine-mesh bags in the winter-spring experiment (-0.0054±0.0005). Macroinvertebrate contribution to the litter breakdown was estimated by the difference of % leaf letter remaining between coarse -mesh bage and fine-mesh bags. Although shredders were more abundant during the winter-spring, their contribution was greater during the spring (50%) than the winter-spring (22∼33%). This result appeared to be due to the change in the chemical composition of leaf letter during processing, and to the seasonal growth patterns of major shredder taxa.

  • Distribution of size class, population regeneration and changes in the population structure of Quercus mongolica were studied from 1994 to 1999 in Mt. Jumbong (128°27' E, 38° 04' N) of Mt. Sorak National Park and Biosphere Reserve in central Korea. Three 20m × 20m permanent quadrats were set up at the elevation of 900m. The vegetation of the study site was dominated by Quercus mongolica and Acer pseudosieboldianum, but little change was observed in the community structure from 1995 to 1999. Most mortality in the study site was observed in small trees of A. pseudosieboldianum and Tilia amurensis. Mean annual growth in dbh (diameter of breast height) of Q. mongolica for 4 years was only 0.09cm, and no ingrowth of saplings (dbh < 2.5cm) into tree class was observed during the study period. Among the 21 Q. mongolica trees studied in the permanent quadrats. all the smaller trees (dbh < 30cm) were established in 1920 ∼ 1950, while many bigger trees (with 40cm < dbh < 80cm) were established in 1750 ∼ 1800, indicating that its establishment was episodic. Distribution of dbh classes among Q. mongolica trees shows that smaller trees were poorly represented, and no saplings of Q. mongolica occurred in the permanent quadrats studied, indicating that currently Q. mongolica is not regenerating well in the study site. Total seed production of Q. mongolica in 1994 was estimated as 88 acorns per square meter in the study site. Rate of predation including caching of acorns was highest in 1994, then declined sharply thereafter. Most of the acorns which managed to survive in the first year were predated in the second year, and only 5% of the acorns produced in 1994 survived into the third year. No seeds produced in 1994 or seedlings germinated from them succeeded to survive to 5 years after seed production. However, seedling emergence rate and seedling survival were high in the early growing season in 1995. These results suggest that predation can be a significant factor in the regeneration of Q. mongolica. and that Q. mongolica is not regenerating well in Mt. Jumbong and needs large scale disturbances for its new recruitment.

  • 본 연구의 목적은 설악산국립공원 및 점봉산천연보호림 일대의 생태조사자료를 활용하여 멧돼지 서식지 적합성 예측모형을 개발하는 것이다. 본 연구의 GIS DB는 2년간 무선송신기를 이용하여 수집한 멧돼지의 서식지 이용 적합성 자료에 입각하여 대상지역의 임상, 영급, 향 경사도 수계 및 임도로부터의 거리 등으로 구축하였다. 서식지 적합성 분석은 전술한 6개의 영향인자를 중첩하여 계산하였고 이때 각 인자의 등급은 대상지의 환경특성을 고려하여 표준화시켜 이용하였다. 서식지 적합성 분석인자는 여름, 가을 및 년중으로 구분하였으며, 적합성은 다시 5등급으로 재분류하였다. 점봉산 일대의 멧돼지 흔적관찰지점을 적합성 평가 도면에 중첩한 결과 일치율이 높아서 모형의 정확성이 높은 것으로 판명되었다.

  • Vegetational changes along elevational and topographical gradients were studied in Mt. Jumbong which is located at the core area of the Mt. Sorak Biosphere Reserve in Kangwon-do Province in central Korea. Two 500 m north-south transects crossing two valleys and a small ridge were laid out, and fifty-one 10 m$\times$10 m permanent quadrats were systematically set up. All trees bigger than 2.5 cm DBH were marked with numbered aluminum tags, and their DBH measured and the species identified. Coverage of plant species in the herb layer were determined in two 2 m $\times$ 2 m subquadrats in each of the permanent quadrats. Thirty-two species of woody plants occurred in the tree layer in the permanent quadrats studied. Quercus mongolica was the dominant species across the study site, and Acer pseudosieboldianum and Carpinus cordata were also important. Quercus mongolica occurred on the ridges and south-facing slopes, and Acer pseudosieboldianum occurred extensively except for valleys. In contrast, Fraxinus mandshurica, Acer mono, Acer triflorum, and Ulmus laciniata were common in valleys. At the herbaceous layer, 112 species were identified. Dominant species were Ainsliaea acerifolia and Sasa borealis on the ridges, Meehania urticifolia on north-facing slopes, and Deutzia glabrata on valleys. Soil environmental factors were compared among the quadrats. pH was lower in the quadrats located on ridges and south-facing slopes, and organic matter was lowest on south-facing slopes. Quadrats located on valleys were generally higher in pH, organic matter, N, P, K, Ca and Mg. DCA ordinations for tree layer and herb layer were carried out in order to identify the dominant environmental factors affecting the distribution of plant species along the environmental gradients. Correlation analysis between ordination axis scores and environmental factors showed that axis one was negatively correlated with elevation and positively correlated with soil organic matter, pH, Ca, Mg, and P, but that axis two was positively correlated with elevation. These results indicate that vegetation responds very sensitively to elevational and topographical gradients although the study area is relatively small with about 100 m in elevational variation.
