최송현,이경재,Choi, Song-Hyun,Lee, Kyong-Jae 한국환경영향평가학회 1996 환경영향평가 Vol.5 No.2
To select the criteria, literature review was made in the quantitative case of conservation biology, foreign country's EIA and domestic ecology. Among them, a few factors was extracted. To applicate the criteria to domestic forest ecosystem, expert opinion survey was executed to the ecologist. The results were summarized as follows; 1. Classification of sites was made of land use system which is related to forest ecosystem or forest conservation. Sites are divided into 3 categories which are nature preservation area, seminature preservation area and urbanized area. Evaluation criteria is consisted of rarity and naturalness. 2. Each area had different criteria composition according to the site characteristics. Criteria of nature preservation area is rarity in the broad sense (distribution pattern of vegetation), vegetation size, successional stage and depth of organic matters. Those of seminature preservation area are rarity in the broad sense (distribution area of vegetation), vegetation size, successional stage, diameter at breath height and depth of organic matters. And those of urbanized area are vegetation distribution in area, successional stage, age of forest and diameter of breath height. The basic data of criterion was gathered by field survey. 3. Evaluation index and total naturalness index was obtained by adding the each criterion. It is made up of two categories-rarity and naturalness. TNi is divided into 3 grades. Grade I is more than 70% for TNi, grade IT is 50~70%, and grade III is below 50%. According to the each grade, permitted action and facilities were suggested.. This research just focuses on the evaluation of vegetation quality and the assessment results do not directly judge conservation or development. To make better evaluation criteria, various fields of forest ecosystem-geological or physical nature environment and fauna ecosystem etc. -will be added wholly to this research.

In order to develop an appropriate set of criteria applicable for environmental impact assessment (EIA) of natural forest 8 items are proposed. The criteria are vegetation distribution area (DA), distribution pattern (DP), size (S), diameter of breast height of tree (DBH), humus (H), sustainment (ST), successional stage (SS) and impact of adjacent ecosystem (IAE), Each criterion has an interval which minimum 1 score to maximum 5 score Forest Evaluation Index (FEI) was obtained as the sum of 8 criteria value. Above 70% is considered to be absolutely conservative and from 50% to 70% range of total score is to be considered conservative. In the case of the Sancho˘ng Pumping-up Power Plant of Mt. Chiri, 8 criteria were applied base on actual vegetation map. Pinus densiflora community got 73%(29 scores) and Quercus variabilis - Q. serrata community got 60%(24 scores). This may be said that this local vegetation has high ecological potentiality. These criteria cannot always be absolutely evaluation tool. So it is expected to take the more time to be developed further, and holistically added by the other field such as fauna, geological feature etc.

변산반도국립공원의 내소사-내변산지구의 식생구조를 파악하기 위하여 30개 조사구를 설치하여 조사를 실시하였다. Classification 기법중 하나인 TWINSPAN을 이용하여 군락분리를 시도하고, ordination기법중 DCA분석을 실시하여 보완한 결과, 군락의 종조성이 불연속적으로 나타났다. 최종 군락 분리결과 군락 I은 소나무군락, 군락 Ⅱ는 소나무-졸참나무군락, 군락 Ⅲ은 느티나무-까마귀베개군락, 그라고 군락 IV는 푸조나무-까마귀베개군락이었다. 이상의 분석결과 변산반도국립공원 남사면지역은 해안쪽은 소나무식생이 계속 유지될 것이나 내륙으로 갈수록 점차 졸참나무 등으로 천이가 진행될 것으로 판단된다. 본 조사지역의 산림식생의 임령은 연륜분석결과 40년을 상회하는 것으로 밝혀졌다. To investigate the vegetation structure of the section from Naesosa to Naebyonsan district, thirty plots which size is 100m2 were set up in the Byeonsan Peninsula National Park. According to the classification(TWINSPAN) and ordination(DCA) analysis which were used for community division, the plots are appeared in uncontiguity with each ones. At the end of classification analysis, the community was divided into the four groups of Pinus densiflora(I), Pinus densiflora-Quercus serrata(II), Zelkova serrata-Rhamnella frangulioides(Ⅲ) and Aphanaghe aspera-Rhamnella frangulioides community(IV). Through the results, Pinus densiflora community coast-sided will be going with status quo, but Pinus densiflora-Quercus serrata community inland-sided will progress toward Q. serrata dominated community. It was turned out that the forest of the Byeonsan Peninsula National Park is about over 40-year-old through tree ring analysis.

This study was executed environmental assessment to determine whether or not the national landuse planning change on the reserved area for a rope way in the ice valley(Eoreumgol) of Miryang. The selected survery area is 1,633,442㎡ and assessed with flora, actual vegetation, degree of green naturality(DGN), sere stage and wild birds. The flora was summarized as 132 taxa which is 90 genera, 117 species, 12 varieties and 3 forms. The actual vegetation was classified 24 types and nature forests like Quercus and deciduous-broadleaf community was distrubuted broadly. Especially Quercus and deciduous-broadleaf communities were assessed high rarity value in Miryang. From the analysis of DGN, it were found out that DGN 8 is 72.5% and DGN 9 is 3.9%. At the analysis of sere stage, the communities were divided 4 with Quercus mongolica, Pinus densiflora, Carpinus laxiflora and deciduous-broadleaf community. Wildbirds was observated as 30 species and 161 ea and Aix galericulata (natural monument no. 327) especially inhabited there. From the above nature ecosystem assessment, the survey area has high quality naturalness, so it was turned out that a rope way construction might be not suitable in survery area.
