순천만 조간대 염생식물조사를 위하여 주요 염생식물군락을 선정하고 식생분포 및 현존량을 조사하였다. 우점군락은 갈대군락(Phragmites communis community), 칠면초군락(Suaeda japonica community), 부들군락(Typha orientalis community), 나문재군락(Suaeda asparagoides community), 모새달군락(Phacelurus latifolius community), 가는갯능쟁이군락(Atriplex gmelini community), 갯잔디군락(Zoysia sinica community), 갯질경군락(Limonium tetragonun community) 및 실망초군락(Erigeron bonariensis community)으로 구분되었다. 칠면초군락은 순천만지역에서 가장 넓게 분포하고 있으며, 군락의 높이는 25∼38cm, 식피율은 90∼100%, 단위면적당 368∼608개체/㎡이었고, 갈대군락의 높이는 100∼250cm, 식피율은 85∼100% 및 단위면적당 320∼368개체/㎡으로 순천만 하구 주변을 중심으로 분포하고 있으며, 해안 염소택지와 하구 기수역을 중심으로 생육하고 있었다. The coastal vegetation was classified by the Braun-Blanquet's method at the wetland of Suncheon-Man. The vegetation of the study area was classified with 9 coastal communities as follows : Phragmites communis community, Suaeda japonica community, Typha orientalis community, Suaeda asparagoides community, Phacelurus latifolius community, Atriplex gmelini community, Zoysia sinica community, Limonium tetragonun community and Erigeron bonariensis community. Suaeda japonica community was major dominant species and was 25∼38cm in height, 90∼100% in cover and 368∼608 individuals per ㎡, and Phragmites communis community was 100∼250cm in height, 85∼100% in cover and 320∼368 individuals per ㎡.

In order to elucidate effects of air pollutants on ecophysiological properties of two Quercus mongolica forest at different levels of air pollution. Seasonal change of soil properties and nutrient content of plants were investigated. Nutrient analyses reveled that leaves in polluted area had lower concentration of Mg and P than the respective components in nonpolluted area. The results indicate that this lower nutrient contents of leaves of Q. mongolica in polluted area were attributed to the limititation of nutrient supply from the soil.

서남해안의 염습지식생을 Braun-Blanquet의 방법 (1964)에 따라 구분하였다. 조사지역의 식물군락은 다음과 같이 구분되었다; (1) 퉁퉁마디 군락(Salicornia herbaceae community)을 포함하여 9가지 해안간석지 식물군락; (2) 매자기 군락(Scirpus fluviatilis community)을 포함하여 5가지 염소택지 식물군락; (3) 띠 군락(Imperata cylindrica var. koenigii community)을 포함한 10가지 사구식물군락으로 구분되었다. 본 연구에서 해안 염습지에 염습지 식생의 대상 분포(zonation)가 분명하게 나타났으며 생육지 유형은 염습지 식생의 구분을 잘 설명하였다. The wetland vegetation of southwestern coast in Korea was classified by Braun-Blanquet's method (1964). The plant communities of the study area were classified as follows: (1) 9 salt marsh communities including Salicornia herbacea communities (2) 5 salt swamp communities including Scirpus fluviatilis communities and (3) 10 sand dune communities including Imperata cylindrica communities. In this study, the zonation of wetland plants within and across coastal wetlands type is quite evident and the types of habitat account well for the classification of coastal vegetation.

The coastal vegetation was classified by the Braun-Blanquet's phytosociological scheme and physicochemical properties of soil was also determined at the salt marsh of Mankyung and Dongjin river estuary. The vegetation of these areas was classified with 8 communities as followes Suaeda japonica, salicornia herbaceae, Phragmites longivalvis, Carex scabrifolia, Zoysia sinica, Aster tripolim, Suaeda asparagoides and Phacelurus latifolia community. Especially the zonations an annual and biennial halophytes were highly affected by surface soil.

The nutrient removal-capacity of four major dominant species distributed in Namchang-chon polluted with livestock wastewater and Samhyang-chon polluted with industrial and domestic wastewater were investigated. Water qualities and soil properties of three polluted sites were a quite different in concentration of nitrogen, SS and Ga. Dominant species in livestock wasetewater were Persicaria thunbergii, Zizania latiforia, Phragmites communis and Oenanthe japanica, those in industrial and domestic were Phragmites communis. Changes of NO₃-N, NH₄-N and P concentrations of culture solution are high in cultivor of Zizania latiforia and Oenanthe japanica. All four species removed NO₃-N most effectively. In experiment used directely polluted water from three areas ; all species from livestock wasetewater uptaked NO₃-N effectively. Phragmites communis from domestic, and Persicaria thunbergii and Oenanthe japanica from industrial and domestic wasetewater removed NH₄-N effectively. All species cultured in industrial waserewater removed P well, and Phragmites communis and Persicaria thunbergii cultured in domestic wastewater removed it moderately.

In order to find out the influence of shading degree on the growth, pod setting, protein contents, RuBPCase activity, photosynthesis and yield in soybean plants, two soybean varieties, Hill and Etaka were cultivated under the 0%(full sun light), 20%, 65% and 90% shading conditions. Protein contents, RuBPCase activity and photosynthesis of leaves in Hill were decreased linearly with the higher shading, but those in Etaka were increased up to 20% shading, and then decreased more rapidly than Hill when the shading was above 65%. Pod sets were decreased with the higher shading degree, and those of the degree were severe in upper nodes. The stem heights were increased in accordance with the shading up to 65%, but stem diameter and No. of branches were decreased linearly with the higher shading degree. The yield of Hill was decreased linearly with the higher shading degree, but that of Etaka were increased up to 20% shading, and decreased inure severely than Hill when the shading was above 65%. From the above results : Etaka is more suitable than Hill to weak shading which occurred in the case of intercropping, companion cropping and alternating cropping, and the shading degree must not go over above 20%.

Hydrophytes were composed of 29 familes 80 species and hygrophytes 27 familes 104 species. Among hydrophytes, emerged plant, floating leaved plant, submerged plants and free floating hydrophytes were added 46, 24, 12, and 8 species respectively in this investigation. Threatened species of Utricularia japonica and Hydrocharis dubia and endangered species of Brasenia schreberi and Euryale ferox were founded in these areas.

임병선,이점숙,이기철,김종욱,임현빈,이승호 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.4

전남 해남군 화원면에 금호방조제 건설 후의 염습지의 습지 환경 및 식생의 분포에 관한 지도 데이터 베이스를 구축하기 위하여 토양의 유기물함량, 총 질소량, 나트륨함량 지도 및 습지의 잠재자연식생도(wetland potential natural vegetation map)를 작성하였다. 토양의 유기물함량과 나트륨함량은 담수가 유입되는 내륙쪽에 인접한 간척지역은 가장 낮은 값을 보였으며, 반대로 해안쪽이 간척지역이 가장 높은 값을 나타내었다. 토양의 sand함량과 총질소함량은 금호방조제 밖의 화원면 마산리에서 가장 낮았고, 내륙쪽에 인접한 간척지역은 가장 높은 값을 보였다. 금호호 주변 간척지의 잠재식생분포는 염분농도가 낮고 지하수위를 통하여 담수가 공급되는 육지쪽에는 갈대군락이, 해안선에는 호수주변으로 갈수록 차례로 나문재군락, 퉁퉁마디군락 및 칠면초군락이 분포할 것으로 추정되었다. To establish the map database on wetland soil environment and vegetation distribution after constructions of the Kumho seawalls in southwestern coastal wetlands in Korea, the maps of soil organic matter, total nitrogen and sodium content and wetland potential natural vegetation were made. Soil organic matter and sodium content were lower in reclaimed area near the land than near the sea. Soil sand and total nitrogen content were lower in the outside of the Kumho Seawalls than in reclaimed area near the land. In the distribution of wetland potential natural vegetation after constructions of the Kumho Seawalls, Phragmites communis community will be distributed in reclaimed area near the land, in which fresh water is streamed and then Suaeda asparagoides, Salicornia herbacea and Suaeda japonica community will be distributed from the land to the sea.
