도시 내 고립된 임지의 경시적 식생특성 변화: 부산광역시 황령산을 사례로
조재형 ( Jae Hyong Cho ),박찬열 ( Chan Ryul Park ),오정학 ( Jeong Hak Oh ),김준수 ( Jun Soo Kim ),조현제 ( Hyun Je Cho ) 한국임학회 2016 한국산림과학회지 Vol.105 No.3
도시화에 의해 고립된 임지의 식생특성 변화를 파악하기 위하여, 부산광역시 황령산을 대상으로 1996년과 2015년에 식물사회학적 방법으로 식생조사를 실시하였다. 식생유형(종조성기준)은 군락군수준에서는 거의 변화가 없었으나 군락수준이하에서는 다소 변화가 나타났다. 단위면적당(/100 m²) 총피도와 평균종수는 각각 1996년 175%, 17종에서 2015년 191%, 19종으로 다소 증가하였다. 구성종의 상대중요치는 아교목층 이하에서 한반도 잠재자연식생인 신갈나무, 졸참나무 등 참나무류는 감소한 반면, 난대 및 상록성 식물인 비목나무, 때죽나무, 구골나무 등과 생태적적응 범위가 넓은 국수나무가 크게 증가하였다. 생활형 조성은 전체적으로 1996년과 2015년 모두 MM-R<sub>5</sub>-D<sub>4</sub>-e로 변화가 없었으나, 휴면형의 경우 반지중식물(H)과 일년생 식물(Th)이 감소한 반면 관목성인 미소지상식물(N)은 상대적으로 높은 증가율을 나타내었고, 종자 산포형의 경우 풍수산포형(D1)은 다소 감소한 반면, 동물산포형(D2)은 70%이상의 증가율을 나타내었다. 상관식생 유형의 공간적 분포 특성의 변화를 대축척(1/5,000) 정밀상관식생도를 작성하여비교하였다. In order to assess th changes in vegetation characteristics over time in the forest-lands which is isolated by urbanization, vegetation surveys based on the Braun-Blanquet phytosociological method was carried out in 1996 and 2015 on Mt. Hwangyeong located in the center of Busan metropolitan city, South Korea. The number of vegetation types based on floristic composition showed no significant changes, the vegetation units under the community levels was more or less represents the difference. the average total vegetation cover and average number of species per unit area (100 m²) was increased 16% and 2 species, respectively. The relative importance value (RIV) for each tree species, Quercus spp. like as Q. mongolica and Q. serrata was decreased, while the warmth-tolerant trees, evergreen broad-leaved trees, and mesophyte like Lindera erythrocarpa, Styrax japonica, Osmanthus heterophyllus, and Stephanandra incisa was increased significantly. Changes of the life form spectrums of vascular plants did not substantially, hemicryptophyte(H) and therophyte (Th) was decreased, while nanophanerophyte(N) was increased significantly. Also through the creating of large-scale vegetation map (based on physiognomic vegetation types) was compared the spatial distribution characteristics of each vegetation types.

The forest vegetation developing on Mt. Inwang, an isolated forestland in Seoul, Korea was analyzed phytosociologically and its spatial distribution mapped out. Using the vegetation map, The characteristics of landscape structures in terms of the number and size of patches are discussed. Forest vegetation of the study area was classified into ten communities, ten groups, and eighty subgroups. Landscape element types were classified into secondary forests, relict communities, introduced plantations, and other elements including urbanized area. Pinus densiflora community, natural forest and Robinia pseudo-acacia community, plantation, formed matrix and some secondary forest elements, relict communities and the ether plantations of small size tended to distribute as small patches in such matrix. The number of patches per unit area in secondary forest elements was more than that in plantation elements. The result in patch size was vice versa. The vascular plant species richness of the landscape element types in Mt. Inwang was found to he positively related to their size. As the results of landscape ecological analyses, it was estimated that differentiation of patches recognized in community level would be related to human interference a and those in subordinate levels to natural process such as progression of succession.

도시림 관리를 위한 식생단위구분과 정밀식생도 작성 : 광주광역시 무등산을 중심으로 On Mt. Moodeung in Kwangju , Korea
조현제,이창석,조재형 한국임학회 2000 한국산림과학회지 Vol.89 No.4
Management units of forest vegetation established on Mt. Moodeung (1,186.8m), a typical urban forest at Kwangju city located in the southwestern Korea, was classified phytosociologically and its spatial distribution mapped out with special reference to its ecological conservation and management. Management units of this area were classified into three categories; twenty-one higher units, ten lower units and nine lowest units, giving a total of 31 zones. Total area for detailed mapping was 2,779.5㏊, of which natural vegetation accounted for 2192.0㏊ (78.9%), residing in most part of this area, artificial vegetation for 159.1㏊ (5.7%), and non-forested area including arable area, burned area and others for 428.4㏊ (15.5%). The ratio of natural forest element showed 93.2%, which is much higher when compared with those of other urban forests.
