2009년에 태안해안국립공원의 현존식생 및 녹지자연도를 조사하였다. 태안해안국립공원의 현존식생은 11개 식물군락과 기타지역으로 구분되었으며, 2차림인 자연림은 곰솔군락, 소나무군락, 낙엽활엽수군락, 소나무-낙엽활엽수군락 등 6개 식물군락으로, 조림지는 곰솔-낙엽활엽수림, 곰솔-리기다소나무림, 곰솔-밤나무림, 아까시나무림 등 5개 수림으로 구분되었다. 태안해안국립공원의 육지면적 중 녹지자연도 8등급 지역이 약 40.6%로 나타났으며, 반면에 녹지자연도 9등급 지역은 13.7%로 나타났다. 태안해안국립공원의 자연경관과 생물다양성 회복을 위하여 조림수종 제거 등 외래종에 대한 관리가 필요하다. This study was conducted to investigate the actual vegetation and Degree of Green Naturality(DGN) in Taeanhaean National Park in 2009. The actual vegetation of the surveyed site was classified into eleven plant communities and the others. Substitutional forest were classified into six plant communities; Pinus thunbergii community, P. densiflora community, Deciduous Broadleaf Forest, P. densiflora-Deciduous broadleaf Forest, etc. and the afforested lands were classified into five forest types: P. thunbergii, P. thunbergii-P. rigida Forest, Robinia pseudoacacia Forest, etc. The area of DGN 8 consisted of 40.66% while the area of DGN 9 consisted of 13.7% when compared with land area of Taeanhaean National Park. For the recovery of natural landscape and biological diversity of Taeanhaean National Park needs to be managed for eliminate to the exotic plants.

북한산국립공원의 현존식생 및 녹지자연도와 외래식물 분포실태를 2007년에 조사하였다. 북한산국립공원의 현존식생은 총 8개의 식물군락과 기타 지역으로 구분 되었으며, 자연림은 신갈나무군락, 신갈나무-소나무군락, 낙엽활엽수림 등 5개 식물군락으로, 조림지는 잣나무림, 리기다소나무림, 아까시나무림 등 3개 산림유형으로 구분되었다. 북한산국립공원의 녹지자연도에서 가장 넓게 분포한 것은 8등급 지역이 약 92.8%였다. 북한산국립공원안에 식재된 수목류는 총 71과 212종류이었고 이 중 자생종은 37과 67종류(31.6%), 외래종은 58과 145종류(68.4%)이었다. 북한산국립공원의 자연환경 회복, 자생식물의 다양성 유지와 자연경관을 향상시키기 위해서는 외래수종에 대한 관리가 필요하다. This study was carried out to investigate the actual vegetation and Degree of Green Naturality(DGN) and distribution of exotic plants replanted in Bukhansan National Park. The actual vegetation of the surveyed site was classified into eight plant communities and crop land, etc. Substitutional forest were classified into five plant communities; Quercus mongolica community, Q. mongolica-Pinus densiflora community, Deciduous broadleaf forest, etc. Reforested lands were classified into three forest types: P. koraiensis forest, Robinia pseudoacacia forest, P. rigida forest, etc. The area of DGN 8 consisted of 92.80% in Bukhansan National Park. The replanted plants in Bukhansan National Park was enlisted as 212 taxa, 71 families. The indigenous native among the replanted species were enlisted as 67 taxa(31.6%), 37 families. The exotic plants were enlisted as 145 taxa(68.4%), 58 families. The exotic plants needs to management that for recovery of natural environment, improvement about maintenance of multiplicity and a site of scenery about natural plants in Bukhansan National Park.

The vegetation structure in the Hoo - Won, Changduk Palace in Seoul was analysed on 10 sites sampled for understanding structure of natural vegetation. The main vegetational survey was conducted during July, 1985 and actual vegetaion and degree of natural vegetaion types were surveyed additionally. The result summarized of this research are as follows. 1) The physical - chemical conditions of soil showed middle class. This might be derived by short succession period from Pine forest to decidious broadleaf forest and artificial impact by human intervention. 2) When considering dominance species by crown story, Quercus aliena was a dominant species over all site and Castanea crenata, Prunus sargentii and Quercus variabilis appeared as a dominant species locally at upper story. Styrax story and Rhododendron mucronulatum, Styrax japonica, Stephanandra incisa and Lespedeza spp. at lower story. 3) The distances kept by trees per crown story are as follows. The mean distances between trees were 4.5-5.5m at upper story, 2.8-3.3m at middle story. On the other hand, the mean distances between dominant species were 6-8m at upper story, 5-9m at middle story. 4) The vegetation in this area was not developed yet into dominant species community according to the similarity analysis. The natural vegetation was dominated by Quercus spp. especially Quercus aliena according to the analysis of species diversity, relative dominance by story and DBH class. On the orther hand, succession to climax stage dominated by shade tolerent species will take a long time due to little appearance of shade tolerence species by previous heavy artificial impacts on understory species. 5) Quercus forest took possesion of 71.3%(27.37ha) of total forest area when considering the actual vegetation and especially Quercus aliena community covered 53.2%(15.21ha). Carpinus laxiflora community, one of the climax species in temperate zone, took possesion of 1.0%(0.3ha) and Pine densiflora was almost disappeared due to species competition. 6) According to the degree of natural vegetation types, the possession of degree of 6-9 was 60.6% and degree of 7-8, substitute vegetation, was 15.5%. The possesion of degree of 9 which consists of over 50 years old trees simliar to natural vegetaion was the highest, 43.1% in this area. Therefore continuous protection in this area of degree of 9 should be recommended.
