한국건설기술연구원 하천실험센터는 이수, 치수, 환경을 조화시키는 하천기술을 개발하기 위하여 2009년 11월 경상북도 안동시 남후면 하아리 낙동강변에 준공되었으며 초당 8톤의 인공홍수발생이 가능한 3개의 실험수로와 유 출입수조, 다목적호수실험장, 저류지 및 연구동으로 이루어져 있다. 본 연구는 하천실험센터의 식생과 3가지 유형(본류형, 자연제방지류형, 인공제방지류형)의 인근 하천식생을 비교분석하여 하천실험센터의 현재 식생환경을 파악하고 차후 연구의 기초선 자료로 활용하기 위하여 수행되었다. 2011년 7월부터 9월 사이에 하천실험센터(급경사수로, 직선수로, 사행수로, 유출수조, 자연식생보존구간), 낙동강 본류, 상리천, 하아천에서 대표성을 갖는 장소 각각 1개 지소를 선정하여 식물상조사 및 식생단면조사를 진행하였으며 조사된 자료를 바탕으로 습생도, 교란도, 외래종율, 종다양성지수를 산출하였다. 또한 군집분석(Cluster Analysis)을 통하여 현재 하천실험센터의 식생환경이 타 조사지의 하천식생과 비교하여 어떤 유사성을 보이는지 확인하였다. 전체조사구간에서 총 108종류의 식물이 출현하였다. 3개의 실험수로는 수 습생식물의 종수가 일반하천의 수 습생식물의 종수보다 적었으며 반면에 육상식물의 종수는 더 많게 조사되었다. 또한 1 2년 식물의 경우 실험수로에서 더 많이 출현하였고 다년생초본과 목본은 소수였다. 하천실험센터의 자연식생보존구간의 경우 총 식물 종수 및 수 습생식물의 종수가 최대값을 나타내었고 식물상의 출현유무를 바탕으로 군집분석을 수행한 결과, 하천실험센터의 실험수로는 낙동강 본류, 상리천, 하아천과 유사도가 낮게 구분되었으며 자연식생보존구간은 낙동강 본류 및 상리천과 유사도가 높게 분류되었다. 하천실험센터의 실험수로는 준공당시 기존의 식생이 모두 제거된 상태에서 인위적으로 조성되었기 때문에 현재까지는 하천식생의 특징이 두드러지지 않으며 육상식생에 가까운 식생환경을 나타내고 있다. 자연식생보존구역의 경우 다양한 버드나무류와 초본류가 정착되어 있으며 타 대상지에 비하여 가장 뛰어난 생태성을 가지고 있다. 하천실험센터는 하천실험을 위한 장소이나 그 자체로 생태가치가 높으며 차후 생태연구, 홍보, 교육활동에 유용하게 활용할 수 있는 잠재력을 내포하고 있다.

Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.

This study was conducted from 2012, which was a year before forest road construction in Minjujisan, to 2015 to verify effects on flora and vegetation change annually before and after the construction, and to provide strategies to examine and manage flora changes. The plant communities in the investigated area around the forest road is separated by the slopes into Quercus mongolica community is on the northwestern slope and Quercus variabilis and Larix kaempferi communities is on the southwestern slope. The annual investigation of flora change before and after the construction showed that there were 209 taxa that had 71 families, 153 genera, 178 species, 27 varieties, and 4 forma in 2015 while there were 66 taxa that had 44 families, 59 genera, 51 species, 13 varieties, and 2 forma in 2012 before the construction, indicating an increase of 143 texa before and after the construction. The investigation of the slope area adjacent to the forest road constructed in 2013, in particular, showed increasing coverage and taxa each year after the construction. This was caused by significantly increased light transmittance after the construction. The investigation in 2015 showed increased coverage of herbaceous layer the year after development of the forest road and the remarkable increase of the coverage of shrub layer in 2015. Further, the coverage on the slope adjacent to the forest road increased more in 2015 than in 2013 and 2014. Therefore, we expect supplementary studies will help to generate a detail manual on flora and vegetation change before and after forest road construction.

This study was carried out to describe the basic materials of the flora and vegetation for the conservation and management of the Dokdo ecosystem. The vegetation types were investigated by physionomy. 53 taxa of vascular plants were found, including 29 families, 48 genera, 49 species, 1subspecies, and 3 varieties. Among the investigated 53 taxa, it was recorded as follows: 2 Korean endemic plants included Sedum kamtschaticum var. takesimense M.Park and Campanula takesimana Nakai and 6 naturalized plants included Brassica juncea (L.) Czern., Sonchus oleraceus L., Bromus catharticus Vahl, Lepidium virginicumL., Chenopodium album L., and Ipomoea purpurea Roth. In particular, common morning glory (Ipomoea purpurea Roth) was reported for the first time in this survey of Dokdo. Based on physionomy, the main plant communities of Dokdo Island were Aster spathulifolius-Sedum oryzifolium community, Aster spathulifolius-Artemisia Japonica subsp. littoricola community, Fallopia sachalinensis-Cyrtomium falcatum community, Echinochloa crusgalli community, Echinochloa crusgalli var. oryzicola community. The debates have been continuing about a mis-identification of plants. To avoid this debate and manage naturalized and cultivated plants, taxonomist surveys and continual monitoring for the Island are required.

Knowing how many species live in a ecosystem is a major work because of the distributions of species are determined by the environmental condition. This study was carried out to investigate the distribution of vascular plants of Gonggeom-ji, located in Sangju-si, Gyeongsangbuk-do, from April to October on 2012. The vascular plants were summarized as 240 taxa including 69 families, 176 genus, 204 species, 2 subspecies, 29 varieties, and 5 forma. Among the investigated taxa, 3 taxa of Korean endemic plants were included. Based on the list of specially designated plants by Ministry of Environment, 11 taxa including Alisma orientale, Monochoria korsakowii and Nymphoides peltata were recorded. The naturalized plants were identified as 26 taxa and the ratio of naturalized index (NI) was 10.8% of vascular plants recorded. 31 taxa of hydrophytes showed 17.8% of Korea. To conservation of wetlands, we suggest that it is required to minimize for unnecessary disturbance of human and to make a strategy for effective management by continuous monitoring for ecosystem alteration.

Floristic composition and medicinal plant resources were investigated in six regions, Mt. Sorak, Mt. Jumbong, Mt. Odae, Mt. Hwaak, Mt. Taebaek, and Mt. Bangtae, represent in Kangwon province. This study was conducted from December. 1995 to October, 1997. Vascular plants in investigated regions were composed of 118 families . 529 genera, 1,138 species, 7 subspecies, 223 varieties and 43 fromae, totaling 1,411 taxa. This taxa was correspond to 34.7% of Korean flora, 4,071 taxa (Lee, 1996b),and 73.8% of Kangwon province flora, 1,913 taxa (Kangwondo, 1996), respectively. Among them, medicinal plant resources was composed of 98 families, 238 genera, 337 species, 63. varieties, and 16 formae, totaling 416 taxa (29.5% of investigated 1.411 taxa). Medicinal plant resources in each regions were distributed ranging from 211(31.4%) to 285(33.1%) taxa.
