  • The forest vegetation established on Mt. Hwangryung located in Pusan, southern Korea was analyzed through phytosociological procedure. Vegetation of the study area was categorized into 14 communities, 16 groups, and 13 subgroups. Vegetation units obtained from such an analysis were shown in a detailed vegetation map (scale 1:5,000). Ecological characteristics of each vegetation unit were discussed on the basis of the principle of restoration ecology. From those results, it was confirmed that some introduced vegetation under excessive artificial interference was in unstable state and then ecological restoration was needed. On the other hand, ecological information and management systems to maintain the urban forest as ecologically healthy state were developed using GIS.

  • Land (scape) ecology is a trans-disciplinary science studying the related systems at the earth surface, in their visual, structural and functional aspects. it serves as an umbrella under which abiotic and biotic sciences, in an integrated way, study the for each relevant land attributes and their interrelations. The spatial aspects of these relations have a special interest. Landscape ecology my have a pure scientific purpose, but usually is executed in an applied context, related to land evaluation for land use and conservation. Depending on the aim and application of the study, one of the land attributes may get special attention. Vegetation mapping may contribute to landscape ecological study but also benefit from it especially in case of reconnaissance surveys. This is because in less detailed surveys of any land attribute, like land form, soil, vegetation, one must necessarily apply landscape ecological principles in the survey methodology, including remote sensing.

  • The vegetation of the Khogno Khan Natural Reserve of the central Mongolia was studied in terms of the Zurich-Montpellier School's method. Twenty plant communities were identified from the three different landscape types such as mountain areas(63%), plains(32%), and wetlands(5%). Actual vegetation map using five vegetation domains was accomplished in order to understand the spatial distribution of regional vegetation. Steppe vegetation of 88% vegetation cover to the whole area is representative, which is composed of a matrix of landscape. The birch-aspen forests and the elm bush forests are relics as a patch distribution. It is recognized that the whole territory of protected area be under the effects of severe grazing from the phytosociological viewpoint.

  • The present studwas undertaken to classify and describe the riverside vegetation around Hanchon (36°27’-36°51’N, 128°15’-128°37’E), a tributary in the upper stream area of Nak-tong River, South Korea by methods of the ZM school of phytosociology. As a result the vegetation was divided into twenty three associations and communities belonging to ten classes. Reflecting various human impacts in the past, the associations and communities of the Artemisietea principis were most plentiful there. The vegetation units obtained in the present study were as follows: A. forest vegetation A-1 Fagetea crenatae:Zelkova serrata community, Larix leptolepis community; B. Shrub vegetation B-1 Salicetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea multiflorae:Stephanandra incisa community, Lycium chinense community; C. Grassland vegetation C-1 Lemnetea minoris:Spirodela polyrhiza-Lemna paucicostata community, C-2 Bidentetea tripartiti:Polygonetum thunbergii, Polygonetum sieboldii-hydropiperis, Panico Polygonetum hydropiperis, Pharagmitetea :Oenantho- Phalaridetum arundinaceae, Phragmitetum japonicae, Miscanthetum sacchariflori, Phragmites australis community, C-4 Artemisietea principis:Artemisia princeps community, Impatiens textori community, Lactuco indicae-Humuletum japonicae, Pueraria lobata-Humulus japonicus community, Pennisetum alopecuroides community, C-5 chenopodietea:Echinochloa crus-galli var. orizicola community, Digitaria adsecendens community, Polygonum nodosum community, C-6 Miscanthetea sinensis: Miscanthus sinensis community, C-7 Plantaginetea:Eragrotis multicaulis-Plantago asiatica community. It is inferred that the endemic vegetation units in the riverside vegetation of Korea are very rare, because most of the vegetation units obtained in the present study are common with those of Japan. Among the above vegetation units, the Salicetum graciliglandis was established as a new association. On the other hand, the associations and communities of classes characterizing the riverside vegetation increased with a decrease of human impacts from the downstream to the upstream in Hanchon, while the number of the naturalized plants was the reverse. Also based on the present phytosociological work, the relation between the vegetation units and their environmental conditions and the restoration ecology and nature conservation of the riverside vegetation were discussed here in detail.

  • 우리나라에 발생하는 해안 식생의 식생 구조에 대하여 식물사회학적 연구를 수행하였다. 총 102개 조사구에 대한 식생자료의 분석은 ZM 학파의 방법을 활용하였다. 국내 해안에 발생하는 식물 군집 구분은 총 11개의 군락으로 순비기나무-돌가시나무 군락, 갯메꽃 군락, 통보리사초-갯그령 군락, 갯잔디 군락, 해홍나물 군락, 방석나물 군락, 나문재-가는갯는쟁이군락, 칠면초 군락, 천일사초 군락, 갈대 군락, 산조풀 군락이 구분되었다. 각 군락 들은 발생지역과 환경에서 다양성을 보였다. 식생 자료에 대한 주성분분석 (PCA) 결과 식물사회학적 군락 분류 결과를 지지하였다.

  • 하구역은 담수와 해수가 섞여 염분 농도와 퇴적물 변화 양상이 특이한 환경 조건을 제공하며, 이와 같은 환경 조건은 타 생태계에서 볼 수 없는 생물다양성을 보유하게 된다. 본 연구는 기수역인 곤양천하구습지를 대상으로 식생의 분포 특성과 생물상을 조사·분석하여, 하구습지의 보전 및 지속가능한 이용을 위한 기초자료를 마련하려는 목적으로 수행되었다. 정수 및 유수역 다년생 초본식생, 염습지식생, 경작지식생, 대상식생 등 총 6개 상관식생형의 25개 식물군락으로 분류되었다. 특히, 하류부에 넓게 분포하는 갯잔디군락이 전형적인 만조 염습지의 특성을 나타내며, 이로 인해 보전 가치가 더욱 높아지고 있습니다. 생물다양성 측면에서는 2012년에 비해 53종이 증가하여 총 1,067종의 생물이 확인되었으며, 멸종위기 야생생물은 15종이 확인되었다. 열린 하구로서 생태적 연결성이 우수하며, 논, 산림, 염습지 등 다양한 지형과 경관이 유기적으로 발달 및 분포하여 기수성 생물 포함 생물다양성 증진에 긍정적으로 역할을 하고 있었다. 따라서 곤양천하구습지의 체계적 보전은 연안까지 연결되는 습지 생태축을 확보하여 생물의 이동 경로를 보호하고 생태적 안정성을 증진시키는 데 기여할 것이다.

  • For landscape ecological management of the isolated forestlands in Incheon city located in the western tip of South Korea, the forest vegetation of Mt. Cheolma was classified phytosciologically and mapped out its spatial distribution at a scale of 1:5,000. Characteristics of forest landscape structures were discussed in terms of the number and size of patches obtained by analy zing vegetation map. Units to manage the forest vegetation were categorized into eighteen communities, seventeen groups, and sixteen subgroups. Landscape elements were classified into five types: secondary vegetation, introduced vegetation for forestry (IVF), introduced vegetation for agriculture (IVA), and other elements. Two hundred and ninety-three forest landscape patches covers 443.3ha, of which IVF accounted for 316.8ha(71.5$\%$), the largest portion, secondary vegetation for 101.2ha(22.8$\%$), IVA for 6.2ha(1.4$\%$), and others for 19.1ha(4.3$\%$). The ratio of natural forest elements of 31.9$\%$ showed that this area was mainly comprised of artificially introduced vegetation, such as Robinia pseudoacacia plantation and Pinus rigida plantation. Forest landscape patches have a mean area of 4.5ha, a density of 66.1/100ha, and a diversity index of 0.87. It was estimated that differentiation of patches recognized in community level would be related to human interference and those in subordinate level to natural processes.

  • 함평만은 좁은 만 입구와 복잡한 지형 구조로 인하여 비대칭적인 퇴적물 이동이 일어나기 때문에, 갯벌의 저질에는 모래 함량이 증가하는 것으로 연구되었다. 모래화 갯벌은 염습지 식생 분포를 변화시키는 것으로 현존식생도와 식생단면도 조사를 통해 분석되었다. 2016년과 2022년의 식생면적 비교에서 절대염생식물인 해홍나물군락은 74% 감소하였다. 반면 임의염생식물인 갯잔디군락은 75% 증가하였다. 특히 갯잔디는 지하경과 줄기의 밀도가 높게 발달하여, 군락 내 모래와 같은 퇴적물을 가둬서 견고한 사구환경을 조성하는 것으로 보인다. 함평만 갯벌의 효과적인 자연보전 관리 계획 수립을 위하여, 갯벌 토성 변화와 식생 군집의 상호작용이 향후 갯벌생태계에 미치는 영향에 대해 통합적 접근이 필요하다.
