기존 자연녹지인 앞산, 금호강/낙동강, 와룡산과 대상지내 산재해 있는 공원녹지를 연결하여 환상형(環狀形)의 그린네트워크를 형성하였다. 그린네트워크 조성에 따른 기존 자연녹지와 공원녹지 사이의 연계 방안으로 도시내 오픈스페이스인 학교용지를 선택하고 이를 연결하는 방안을 제시하였다 공원녹지의 위치상 1면이상이 도로와 접하고 있어 이를 연계하기 위한 가로공간의 녹화를 추진하여 녹지축을 연결하는 방안을 제시하였다. 또한, 도시내 자연녹지 중 도시하천의 역할을 분석하여 본 결과, 대상지내 그린네트워크를 조성하기 위해서는 하천변을 녹화하는 계획을 추진하여야할 것으로 사료된다.

This study was carried out to investigate the actual vegetation and Degree of Green Naturality(DGN) in Naejangsan National Park in 2010. The actual vegetation of the surveyed site were classified into twelve plant communities and the others. Secondary forest were classified into eight plant communities; Pinus densiflora community, Deciduous broadleaf forest, Quercus mongolica community, etc. Afforested lands were classified into four forest types: P. rigida -P. densiflora forest, P. rigida forest, etc. The area of DGN 8 consisted of 60.58% while the area of DGN 9 consisted of 3.62% when compared with land area in Naejangsan National Park. The exotic plants needs to be managed for recovery of natural landscape and biological diversity in Naejangsan National Park.

The present study was carried out to investigate both the actual vegetation and the degree of green naturality in the Chiaksan National Park. The results obtained are in the follows; The actual vegetation in the Chiaksan National Park were classified into 11 communities, including with the farmland and afforestation areas. According to the results, the Pinus community, as 36.83%. were the most largest community, and the Quercus mongolica, 22.35%. Quercus mongolica-Pinus densiflora community, which is mixed forest, 7.37%, and Pinus densiflora-Quercus mongolica community were 6.63%. The pure and mixed forest with these two species of Pinus densiflora and Quercus mongolica were the dominant species in the comunities of the area. The Degree of Green Naturality 9 was the widest area as 35.9% in the total area, the second was the Degree of Green Naturality 8 at 28.5 %.

효율적인 자연환경보전을 위한 방법론상의 선결과제는 자연환경에 대한 신뢰할 수 있는 기초조사 자료를 확보하고 이를 기반으로 하여 효율적인 보전정책을 수립하는 것이 필요하다. 우리나라의 환경부 등 관련기관이나 미국, 영국, 독일 등 각 국의 환경관련기관에서 사용하고 있는 자연환경에 대한 기초 자료는 대부분 현장조사에 기반을 두고 있거나 항공사진에 의거하여 확보되어지고 있다.(중략)

As data basic to policy in nature conservation, the Degree of Green Naturality (DGN) survey was usually carried out. This also explains the impact of human interference to natural environment. Gongju gun and Yeongi gun were surveyed in the summer of 1983 to determine the DGN of these districts. Then, the surveyed DGN was compared to the existing standard. The results obtained appeared that the average DGN of these districts ranged about 5.1 to 5.9 and especially the ratio of DGN 7-graded area was high. Because of difficulties in applying the existing standard directly to middle part of Korea, further improvement on the existing standard for ranking or surveying the DGN should be reconsidered.

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.

The objectives of this study were to determine how land use pattern in Taejon the sixth largest city in Korea has changed with urbanization. Degree of green naturalness (DGN) was used to analyze land use pattern from 1990 to 1998. Number of 1km$\times$1km grids numbers of satistical land use data and compared rate of population increase quantified land use pat-tern. The rate of population increase of Taejon was 27.8% from 1990 to 1998. Eight degrees of DGN were identified with secondary forest(grade 7) occupied the largest area (203 grids: 37.5%) of the total 541 grids in 1998. The changes in land use were compared among 1990, 1994 and 1998. Grade 1 increased by 9 grids while grade 2 decreased by 6 grids. Likewise paddy field decreased by 10km2 from 62 to 52km2 dry field and forest also decreased by 4km2 and 1km2 respectively while residence and factories increased by 10km2 and 0.5km2 respec-tively. The green space was mostly distributes in a national park and greenbelts in the outer zone of the city. As a result paddy and dry fields in central area of the city have been changed to residential and industrial areas. The city environment in term of DGN reduced its quality and quantity.

공원녹지가 군시내에서 수행하고 있는 역할에 대해 학자들은 크게 '주민을 위한 위락공간으로서의 역할' '도시구조를 이루는 한 요소로서의 역할' 그리고 '도시 생태계의 기반으로서의 역할'등 크게 세가지로 구분하고 있다. 본 연구는 대도시 주민들이 인식하고 있는 도시공원녹지의 역할을 그들의 이용과 가치관을 중심으로 설문조사에 기초한 결과의 일부이다. 조사에 의하면, 주민들은 대개 공원녹지를 그들의 위락공간을 위한 장소로서 인식하고 그 역할에 동의하고 있는 것으로 나타났다. 최근, 도시·조경계획분야에서 크게 논의되고 있는 생태학적 개념에 근거한 도시공원녹지의 '도시내 자연'으로서의 역할에 대한 주민의 인식이 전문가들의 열의에 배해 많이 높지 않음을 보여 주었다. 그러나 이는 위락공간으로서 역할 다음으로 중요도가 인식되고 있는 만큼 도시내 자연으로서의 공원녹지 역할을 높이기 위해서 학자들 사이에 구체적인 논의와 실증적인 연구가 뒤따라야 할 뿐만 아니라 주민들의 의사와 합의가 있어야 할 것으로 생각된다. 한편 도시공원녹지의 역할에 대해서는 도시주민의 사회적인 변수 특히 성, 교육수준, 임금수준 등에 따라 차이가 있는 것으로 나타나 도시공원녹지 계획시 이들 변수에 대한 고려가 있어야 할 것이다.
