국토의 효율적인 이용은 국가가 추구하는 궁극의 목표이다. 우리나라는 65%가 산지로 되어 있어 산지의 효율적인 관리는 무한의 산림자원 증식은 물론 환경개선에 중요한 요소이다. 그러나 산림의 현존 가치가 적다하여 타용도의 임지전용이 원칙 없이 이루어지고 있어 산림관리에 있어서 문제는 물론 국민 생활 환경을 악화시키는 요인이 되고 있다. 그래서 1979년부터 1944년 까지의 임지전용실태를 분석 하였으며 1994년에 근교 및 오지에 있어서 산림전용현상을 조사하여 문제점을 분석한 결과 다음과 같다. 1. 산림청에서는 보전임지, 생산임지 구분을 위한 정확한 입지조사, 경제조사를 실시하여 분류하고 확고한 산림관리체계를 확립해야 한다. 2. 모든 산림의 운영관리에 있어서 산림법이 우선권을 갖도록 법적인 뒷바침이 필요하다. 3. 과거 임지 전용은 대부분 농업목적이었으나 1980년 후반 부터는 주택, 공공시설, 공장, 국민 휴양시설로 바뀌어 지고 있다. 4. 임지 전용에 있어서 외국의 경우와 같이 환경보전을 우선하는 광산으로부터 30m주위산림, 공장부지의 25%, 거주단지의 20%, 휴양시설단지의 60% 산림은 보전시켜서 쾌락한 산림이 유지되도록 한다. This study carried out for the resolving of the problem on the forestland conversion. First of all investigated the diversity act of forestland conversion and next surveyed the difference real condition for this at the urban forest at Kyunggi, Chunbuk, and Chungbuk province area by admission data at the remote forest. In the case of act system, the forestland conversion activity is not an activity position, always it was surpressed under another law for example city planning act or national land utilyzing act. New society is demanding more convenient life and environmental good condition. The forest has big charge of amenity environment. Also the forestland is useful good land for another industrial land specialy in the developing urban area. Forest office should be supply hormony with two objects. For this aim. Forest office have to classified clearly the constant land into forest and changeable forestland for another object after detail suevey physical and economical condition. Total area conversion forestland is average 7,000 hectares per year 1797-1994. In old day forestland conversion had been farmland for the food. But now it was big changed into mining, a pasture, a factory, new roadland. Speciall urban area increased apartment, land a restaurant, Hotel land, leisure facility land like a golf cource, ski cource, On the system of new forest policy must be charged active position about conversion forestland. Therefore even thought changed forest continue the protect sanitary forest like developed county system could not cut the tree in side 30m from mining area, 25% of facory area, 20% of residence area, 60% of leisure area.

장규관,송호경 한국임학회 1997 한국산림과학회지 Vol.86 No.2

One hundred Sixty two quadrats were sampled from natural forests, in Kangwon-do and Kyungsangbuk-do. On the basis of Mueller-Dombois & Ellenberg method, field survey, which accounts for the characters of the species structure of Pinus densiflora community and Quercus mongolica community, was carried out between 1991 and 1994. To analyze the data, CCA ordination and D.B.H, analysis were used. 1. DBH analysis showed that Pinus densiflora community is likely replacing Quercus mongolica or Quercus variabilis community. DBH analysis also showed that Quercus mongolica - Lindera obtusiloba community balances among the Quercus mongolica, Fraxinus rhynchophylla, and Tilia amurensid in the canopy, and that Quercus mongolica-Abies nephrolepis community, mixed forest balances among the Quercus mongolica, Pinus koraiensis, and Abies nephrolepis in the canopy. In general, Quercus mongolica seems to remain as a dominant species. 2. A certain correlation seems to exist between nutrients types and Pinus densiflora community. Quercus mongolica prefered to grow in the medium elevation area that has medium level of total nitrogen, organic matter, and C.E.C. Pinus densiflora, Quercus serrata and Quercus variabilis were found in the low elevation area that has low level of total nitrogen, organic matter, and C.E.C. 3. There seemed to be a certain correlation between nutrients types and Quercus mongolica community. Quercus mongolica and Acer pseudosieboldianum was distributed in the slope area that has medium level of Mg^(++), Ca^(++), and C.E.C., while Abies nephrolepis, Taxus cuspidata and Pinus koraiensis in the high elevation and ridge area that has low level of Mg^(++), Ca^(++), and C.E.C. Carpinus laxiflora and Abies holophylla were found in the medium elevation area that has medium level of Mg^(++), Ca^(++), and C.E.C., while Kalopanax pious, Carpinus cordata and Acer truncatum in the moderately moist and valley area that has high level of Mg^(++), Ca^(++), and C.E.C. Pinus densiflora and Fraxinus rhynchophylla seemed to prefer the slightly dry, low elevation and ridge area.

Assay-guided fractionation of the methanol extract of the leaves of Albizzia julibrissin has furnished quercitrin (1) and afzelin (2) as the scavengers of DPPH radical. Quercitrin and afzelin showed scavenging activity of DPPH free radical with the IC50 values of 17.3 and 71.5 ${\mu}M$, respectively

식물사회학적 방법과 TWINSPAN 에 의한 강원도 신갈나무림과 분류에 관한 연구

장규관,송호경,김성덕 한국임학회 1997 한국산림과학회지 Vol.86 No.2

Employing the releve´ method of Muller-Dombois & Ellenberg and Braun-Blanquet, 100 plots were sampled in the Quercus mongolica community of Mt. Odae, Mt. Chumbong and Mt. Jungwang in Kangwon-do. To analyze the data, phytosociological method and TWINSPAN were used. 1. Quercus mongolica forests were recognized as Quercus mongolica-Acer pseudosieboldianum community group, and were classified into Quercus mongolica - Carpinus cordata community, Quercus mongolica Acer pseudosieboldianum typical community, Quercus mongolica -Lespedeza maximocoiczii community and Quercus mongolica - Abies nephrolepis community by phytosociological method. Quercus mongolica - Carpinus cordata community was subdivided into Acer mandshuricum subcommunity and typical subcommunity. 2. According to the classification of TWINSPAN, it was categorized into five groups, such as Quercus mongolica - Acer mandshuricum community, Quercus mongolica - Carpinus cordata community, Quercus mongolica -Acer pseudosieboldianum community, Quercus mongolica -Lindera obtusiloba community, and Quercus mongolica - Abies nephrolepis community. 3. Since the results of phytosociological community classification, which identify five groups of the community, were consistent with that of TWINSPAN, it proved that these two methods could be complement when one do a community classification.

宋鎬京,張圭寬 忠南大學校環境問題硏究所 1993 環境硏究 Vol.11 No.-

서어나무류 群落의 種 造成과 立地와의 關係를 究明하기 위하여 서어나무군락 11個所, 개서어나무군락 22個所, 까치박달나무군락 7個所를 選定하고, DCCA 方法을 使用하여 分析한 結果는 다음과 같다. 1. 서어나무군락에서 重要値가 높은 種은 서어나무, 쪽동백나무, 신갈나무, 졸참나무, 대팻집나무, 당단풍, 까치박달나무, 물푸레 나무, 사람주나무 등의 순이다. 개서어나무 군락에서 重要値가 높은 種은 개서어나무, 졸참나무, 서어나무, 생강나무, 신갈나무, 고로쇠나무, 당단풍, 비목나무, 쪽동백나무 등의 순이다. 까치박달나무군락에서 重要値가 높은 種은 까치박달나무, 신갈나무, 서어나무, 쪽동백나무, 당단풍, 졸참나무 등의 순이다. 2. 主要 優占種의 種 多樣性은 서어나무군락이 가장 높고, 까치박달나무군락이 가장 낮았으며, 群落別 土壤 分析 結果를 보면 개서어나무군락이 C.E.C.를 제외한 全窒素, 有機物含量, 有效燐酸, K+, Ca++, Mg++ 等의 養料가 양호한 것으로 나타냈다. 3. 群落과 環境 要因들과의 상관관계를 보면, 개서어나무군락은 全窒素가 많은 곳에, 서어나무군락은 海拔高가 높은 곳에 주로 分布하고 있으며, 까치박달나무군락은 全窒素가 낮고 高度가 중간인 部分에 주로 分布하고 있다. On the basis of Braun-Blanquet, 40 quadrats were sampled by the releve method of Muller-Dombois & Ellenberg in natural forests of Mt. Chiri, Mt. Deokyu, Mt. Kyeryong, and Mt. Sokri. The quadrats were sampled 11 plots in Carpinus laxiflora forest, 22 plots in C. tschonoskii forest, and 7 plots in C. cordata forest. The method of DCCA were introduced to elucidate the relations of site factors and species composition in the same quadrats. The dominant tree species distributed in the region of Carpinus laxiflora communites were C. laxiflora, Styrax obassia, Quercus mongolica, and Q. serrata in descending order. The dominant tree species distributed in the region of Carpinus tschonoskii communities were C. tschonoskii, Q. serrata, C. laxiflora, and Lindera obtusiloba in descending order. The dominant tree species distributed in the region of Carpinus cordata communities were C. cordata, Q. mongolica, C. laxiflora, and S. obassia in descending order. The species diversities of major dominant species recorded the highest value in the communities of Carpinus laxiflora but the lowest value in the communities of C. cordata. The nutrient contents of total nitrogen, organic matter, available phosphorus, K+, Ca++, and Mg++ except of C.E.C. value were the highest values in the forest soils of C. tschonoskii communities. In the relations of major species communities and environmental factors, Carpinus tschonoskii communities were distributed in the good nutrition of total nitrogen, C. laxiflora communities in the high elevation area, C. cordata communities in the poor nutrition of total nitrogen and in the medium elevation area.
