In order to get basic data for flood plain restoration, we surveyed the woody vegetation in Korean natural rivers and analyzed the species' characteristics with regards to patterns of richness and diversity. These characteristics were higher in hard wood forests than those in soft wood forests, such as Salix spp. community. Futhermore, they were the highest in the Prunus sargentii-Pinus densiflora community(H' 1.095), and the lowest in the Carpinus laxiflora community(H' 0.118) among the hard wood forests. Species' richness diversity were the highest in the Salix gracilistyla community, but the lowest in the S. koriyangi community or S. koreensis community among the soft wood forests. With regards to the dominant index, just one community is over 0.9, 13 communities are between 0.3-0.7 and 15 communities are less than 0.3. The Salix koreensis community was the highest at 0.931, and Prunus sargentii-Pinus densiflora community was the lowest at 0.13. Species' richness and diversity was significantly correlated with tree layer coverages and degree of slope. These results mean that in order to increase plant species diversity in flood plains planted hard woody trees, such as oaks and fir, are needed to suit environmental conditions with steeper slope and lower canopy coverage.

This study was carried out to analyze forest vegetation in Seodaesan of Geumsan, Chungnam Province. Employing the releve method of Braun-Blanquet and quadrat method, 36 plots were sampled in forest of Seodaesan. The sub-communities were classified into Pinus densiflora, Acer pseudosieboldianum, and Carpinus laxiflora sub-community of Quercus mongolica community. The importance values were 77.07 in Quercus mongolica, 40.79 in Pinus densiflora, 17.03 Fraxinus rhynchophylla, 14.06 in Fraxinus sieboldiana, 13.99 in Quercus serrata, 12.93 Acer pseudosiebotdianum. Coverage rate was 84.6% in tree layer, 52.8% in subtree layer, 29.1% in shrub layer, 27.9% in herb layer, respectively. Most of the DBH of Quercus mongolica and Pinus densiflora was between 5cm and 20cm. Therefore, Quercus mongolica and Pinus densiflora might be dominant species in the study area for several decades. Acer pseudosieboldianum and Carpinus laxiflora sub-communities were distributed mainly in a high-altitude and northern and north-western area. Pinus densiflora sub-community was distributed mainly in a low-altitude and western area.

Vegetation and soil conditions of four sites in west coastal forests in South Korea, were examined to analyze the relationship between Pinus thunbergii forests structure and soil conditions. The P. thunbergii forests were divided into four clusters; 1) P. thunbergii - Prunus sargentii var. sargentii, 2) P. thunbergii - Robinia pseudoacacia, 3) P. thunbergii - P. densiflora and 4) P. thunbergii - Quercus serrata. The soil of each site was poor in chemical characteristics but good enough for land plants to grow because of its low salt concentration. According to the results by CCA Ordination, certain excessive soil nutrition has influenced on vegetation and specific species distribution. Forty eight species were found in the whole sites of coastal forests and some species appeared in every site. They are P. thunbergii, R. pseudoacacia, Rhus chinensis, Idesia polycarpa and Morus alba. For the tree species importance value, P. thunbergii was followed by R. pseudoacacia, Q. serrata, P. densiflora, Celtis sinensis, M. alba, I. polycarpa and Q. mongolica in order.

This paper is performed to study for the plants ecosystems for the rural community forest of designated as natural monument. In addition, it is also proposed the plan of the rural community forest's conservation and restoration for avoiding to the destroy of indiscriminate development such as land-use, cultivation. The rural community forest is a mirror that reflect the regional culture and history, as well as environment. According to this view, undoubtedly, we need to recognise the formative background of rural community forest, the relations between the environment around and the characteristic of plants ecosystem comprehensively. For the purpose of proposing to the plan of rural village forests' conservation and restoration, therefore, this study is: 1) reviews the previous research and ancient documents, and 2) surveys the vegetation structure and the growing conditions in rural village forest directly.

The study for the estimation potential natural vegetation was estimated the occurrence probability distribution using geographic information system(GIS) in Bukhansan National Park. Correlation and factor analysis were analyzed to estimate probability distribution. Coefficients were calculated by logistic regression analysis. Correlation coefficients were significantly at the 0.01 level. Commonality of elevation, annual mean temperature, warmth index and potential evapotranspiration were high value, but topographic index was low value. Communities of over the 0.3 points distribution probability, Quercus mogolica communities were the largest area, 76,940,900 $m^2$, Pinus densiflora communities area was 860,800 $m^2$, Quercus acutissima communities area was 500,100 $m^2$ and Quercus variabilis communities area was 1,000 $m^2$, but Q. aliena, Q. serrata, Carpinus laxiflora and Zelcova serrata communities was not appeared. Therefore, potential national vegetation of Bukhansan national park was likely to be Q. mongolica community, P. densiflora community, Q. acutissima community and Q. variabilis community.

This study was done to recommend a method for conserving the habitat of Amblyotropis verna grown naturally in campus of the Kyungpook National University at Daegu city. Vegetation characteristics and morphological characteristics of each individual were analyzed for the condition of the population at the growing season from May to June in 2010. Totally 11 vegetation data were collected and analyzed, and one vegetation community including Amblyotropis verna (Amblyotropis verna-Zoysia japonica community) was found. We found that the growing condition was not good with severe stamping and disturbance. The location-determining method by PCoA analysis showed the physical texture in soil was a critical factor determining the spatial distribution of the Amblyotropis verna-Zoysia japonica community. And the analysis of morphological characteristics found that light condition and soil hardness were the main ecological factor determining the size and form of each individual. Finally, this study recommend that minimizing impacts by human stamping and artificial disturbance and reducing the water stress were the best ways for the conservation of Amblyotropis verna habitats.

본 연구는 2006년 7월부터 2008년 4월까지 한국 서남해안의 대표적인 18개 해안 염습지에서 생육지와 토양특성을 조사하여 서남해안 염습지 식생복원을 위한 기초자료를 제시하였다. 조사지역은 염습지의 생육지 유형에 따라 1차적으로 해안성 염습지와 하구성 염습지로 구분하고, 2차적으로 해안성 염습지는 점토성 염습지, 사질성 염습지, 사구성 염습지, 하구성 염습지는 염소택지와 기수성 염습지로 구분하였다. 생육지 유형별 주요 식물군락은 점토성 염습지에서는 갈대군락, 천일사초군락, 칠면초군락, 사질성 염습지에서는 갈대군락, 갯잔디군락, 천일사초군락, 퉁퉁마디군락, 큰비쑥군락, 해홍나물군락, 사구성 염습지에서는 갯그령군락, 통보리사초군락, 순비기나무군락, 염소택지에서는 갈대군락, 갯잔디군락, 해홍나물군락, 천일사초군락, 하구 염습지에서는 칠면초군락, 갈대군락, 천일사초군락, 나문재군락으로 나타났다. 염생식물 군락분포지역의 토양 환경은 염생식물의 생육지 특성에 따른 염생식물군락과 토양의 차이가 나타났다. 따라서 해안 염습지를 복원할 경우, 염습지를 대상으로 생육지 토양의 물리적 특성, 이화학적특성을 파악하여 생육지 조건에 맞는 염생식물을 선정하고, 이식한 후 자연식생이 형성된 지역을 중심으로 점차 확장시킴으로써 염생식물이 안정적으로 정착, 발아, 생장하는데 유리할 것이다.

서울시 도시생태계 중 산림지역 식물군집구조를 분석하고 이의 대책을 수립하기 위하여 14개지역 56개 조사구(1개 조사구당: 400m$^{2}$)를 설치하고 식생조사를 실시하였다. 전체 56개 조사구는 DCA에 의하여 소나무군집, 아까시나무군집, 리기다소나무군집, 현사시나무군집, 상수리나무군집, 신갈나무군집 6개 군집으로 분리되었다. 식물군집구조 분석결과 추정되는 천이경향은 소나무, 아까시나무, 리기다소나무, 현사시나무, 리기다소나무$\$\longrightarrow$ $ 신갈나무, 졸참나무로 추론되며 극상수종인 서어나무로의 천이경향은 환경오염영향 등의 원인으로 판단하기가 어려웠다. Shannon의 종다양도는 1.1381~1.2694이었고 토양산도는 전지역이 pH 3.18~4.76으로 산성토양이었다.
