This study was carried out to investigate the distribution status and urbanization index of the naturalized plants. For this purpose, 7 cities and counties in the eastern area of Jeollanamdo were selected and investigations were conducted on a total of 14 sites, during the period of March 2006 to November 2008. The naturalized plants were identified as 123; 22 families, 75 genera, 118 species, and 5 varieties. As for the urbanization index, Suncheon city had the highest level of urbanization (33.45%) and Gurye county the lowest level of urbanization (20.21%). Classification families were as follows: Compositae 40 kinds (30.1%) Gramineae 17 kinds (12.8%) and Leguminosae 14 kinds (10.5%). Major communities of naturalized plants consisted of 20 communities including Erigeron annuus community, Erigeron canadensis community, Alnus firma community, Amorpha fruticosa community, Oenothera odorata community, Bidens frondosa community, Coreopsis tinctoria community, Ambrosia artemisiifolia var. elatior community etc. Invasive naturalized plants consisted of 5 taxa: Ambrosia artemisiifolia var. elatior, Ambrosia trifida, Eupatorium rugosum, Paspalum distichum var. indutum and Paspalum distichum. The distributional characteristics of naturalized plants were divided on the basis of six areas associated with ecological characteristics of a habitat.

동해안 지역에서 발생되는 대형 산불의 원인은 건조주의보, 영동지역에서 불어오는 강한 바람, 소나무의 단순림, 임도 유무와 상태 등을 들고 있다. 조사 대상지인 삼척 검봉산 일대는 기존 소나무가 우점하는 곳으로 2001년 복원을 위해 소나무, 곰솔, 굴참나무 등을 조림하였고, 일부는 자연복원을 하였다. 복원 이후 21년 지난 현재 삼척 검봉산 일대 산불피해 복원지역의 식생은 크게 굴참나무-소나무군락, 소나무신갈나무군락, 곰솔-소나무군락으로 나누어지는 것으로 나타났다. 산불피해지 식생 회복은 굴참나무, 소나무, 곰솔 등 조림으로 현재 식생은 산불 발생 이전의 임상으로 회복되고 있다. 특히, 산불의 유형 중 지표화 피해지역은 하층 식생의 피해가 크다. 기존의 소나무는 결실된 종자를 비산하여 치수를 발생시켜 자연복원의 속도를 높이고 굴참나무를 활용한 인공복원은 맹아를 발달시켜 본인의 영역을 확장하는 전략을 지니고 있다. 단, 입지적 환경이 동일하다는 전제 조건에서 숲에서 재생 기작이 진행되는 자연복원보다는 인공복원이 회복시간과 종다양성이 높은 측면에서는 효과적인 것으로 결론을 지을 수 있다. 식생군락을 분류한 결과 굴참나무-소나무군락, 소나무-신갈나무군락, 곰솔소나무군락으로 3개 군락으로 나누어졌다. 인공복원지에 식재한 굴참나무, 소나무, 곰솔은 복원 이후 지속적으로 해당지역의 식생이 우점종으로 자생하고 있는 것으로 나타났으나, 소나무-신갈나무군락의 경우 참나무과 식물인 신갈나무와 굴참나무, 졸참나무가 교목층과 아교목층에 자연유입되고 있어 향후 신갈나무가 우점하는 활엽수림으로 천이 될 것으로 예상된다. 군락의 종다양도지수는 낙엽활엽수가 우점하는 굴참나무-소나무군락이 가장 높게 나타났으며, 침엽수림인 곰솔소나무군락이 가장 낮게 나타났다. 산불피해지 식생은 조림수종에 영향을 크게 받으며, 21년이 지난 현재 산불 이전 임상으로 회복되는 경향을 나타내었다. 향후, 효과적인 복원을 위한 DB구축 및 모니터링자료 마련을 위해 산불피해지에 대한 지속적인 식생조사를 통한 자료구축이 필요하다.

This study was carried out to classify forest vegetation structure of Mt. Gaya from April to October in 2006 using phytosociological analysis methodology of Z-M schools. One hundred study sites(quadrat) were surveyed in the area. The forest vegetation was classified into 3 community groups such as Pinus densiflora community group, Cornus controversa community group and artificial forest group. P, densiflora community group was subdivided into 4 communities such as Rhododendron schlippenbachii community. Salix gracilistyla community, Meliosma oldhamii community and P. densiflora typical community. R. schlippendbachii community was subdivided into Potentilla dickinsii group(subdivided into Carpinus coreana subgroup and Melandrynum firmum subgroup) and R. schlippenbachiitypical group. Cornus controversa community group was also subdivided into 4 communities such as Hovenia dulcis community, Quercus aliena community, Ribes maximowicianum community and C. controversa typical community. Artificial forest type indicated 3 communities such as Larix leptolepis community, Pinus rigida community and Castanea crenata community. Accordingly, the vegetation pattern of the surveyed areas were classified into 3 community groups, 11 communities, 2 groups, and 2 subgroups and the forest vegetation was classified into 13 units in total. It is also believed that C. coreana subgroup and M. oldhamii community could be a source for a significant basic data for making vegetation hierarchy and forest distribution zone in the Korean peninsula. H. dulcis community was also considered to be one of the important genetic resources; therefore, those distribution areas are required to be institutionally protected and managed in the near future.

Vegetational structure and successional sere were investigated for Paryeongsan Zone in the Dadohaehaesang National Park incorporated in National Park in 2011. To do so, seventy-five plots($100m^2$) were set up and surveyed. The surveyed plots were divided into six groups according to the analysis of classification by TWINSPAN; (I) Quercus acutissima community, (II) Q. serrata-Carpinus tschonoskii var. tschonoskii community, (III) Pinus densiflora-Q. mongolica community, (IV) Q. variabilis community, (V) P. rigida-Q. variabilis-P. densiflora community, (VI) Chamaecyparis obtusa community. The results of vegetation structure analysis were. I, IICommunity, were expected that the deciduous oak trees with deciduous oak trees or Carpinus tschonoskii var. tschonoskii competing with oak trees would flourish in a deciduous broad-leaved forest. III, VCommunity, were expected that the P. densiflora and P. rigida competing with oak trees would flourish in a deciduous broad-leaved forest. IVCommunity, have expanded the influence of Q. variabilis, but understory will be developed next ecological succession by a high percentage of Machilus thunbergii in frequency of warm-temperate trees. VI Community, Chamaecyparis obtusa community were expected continue. This Chamaecyparis obtusa community is picked thinning Chamaecyparis obtusa as moving purpose of National Park, it will be inducement a plant vegetation succession to the natural forest. Frequency of warm-temperate trees in the Paryeongsan Zone of warm temperate climate zone was a total 9 species, Machilus thunbergii, Eurya japonica, Elaeagnus macrophylla, etc.
