본 연구는 서남해 다도해 해상국립공원내의 대표적인 5개 상록활엽수군락인 후박나무, 동백나무, 구실잣밤나무, 붉가시나무 및 가시나무군락에서 생육지의 지형적 특징 토양환경 및 산림지역지수(FSQI)를 측정하였다. 군락분포는 동백나무와 후박나무군락이 10。이하의 완만한 경사지로써 북사면의 계곡에, 가시나무와 붉가시나무군락이 15。이상의 급한 경사지로써 남동사면에, 구실잣밤나무군락이 이들 사이에 주로 형성되었다. 식생구조는 일부 보존림을 제외하고는 대부분의 군락에서 DBH가 10㎝이하, 수고 8m미만인 맹아림이었다. 토양요인중 전기전도도, 질소함량 및 인함량 등은 후박나무군락에서 가장 높았고, 그 다음으로 동백나무, 붉가시나무 및 구실잣밤나무 순으로 낮았다. 삼림지역지수(FSQI)의 평균값은 후박나무, 동백나무, 구실잣밤나무, 붉가시나무, 가시나무가 각각 16.42, 15.72, 13.28, 9.36 및 11.80이었다. 이상의 결과에서 상록활엽수림의 분포는 지형적 특성을 나타내는 FSQI와 밀접한 관련이 있는 것으로 나타났다. To elucidate main factor affecting species distrubuttion, the five representative evergreen broad-leaved communities of camellia japonica, Machilus thunbergii Castanopsis cuspidata var. sieboldii, Quercus acuta and Quercus myrsinaeforlia were copared to topographic position, soil properties and Forest Site Quality Index(FSQI) in Dadohae National Marine Park. Camellia japonica and Machilus thunbergii are abundant on northern slopes in valley position whereas Quercus myrsinaeforlia and Quercus acuta were most abundant on southestern slopes in high elevation. Castanopsis cuspidata var. sieboldii was occured between intermediate position of those. Dominant species of vegetation were mainly a sprout forest whose DBH and height were within 10 cm and 8 m respectively. Soil properties did not enfluence on community distribution but electric conductivity, total nitrogen and phosphorus contents of soil decreased in the order of Machilus thunbergii, Camellia japonica, Quercus acuta and castanopsis cuspidata var. sieboldii community. Mean values of FSQI in the communities of Machilus thunbergii, Camellia japonica, Castanopsis cuspidata var. sieboldii, Quercus acuta and quercus myrsinaeforlia were 16.42, 15.72, 13.28, 9.36 and 11.80 respectively. These results indicate that distribution of evergreen broad leaved communities were highly associated with FSQI of site quality.

韓國 西南海岸의 海藻資源 實態에 關한 硏究

崔燾成 木浦大學校沿岸環境硏究所 1992 沿岸環境硏究 Vol.9 No.1

1990년 4월부터 1991년 4월에 걸쳐 한국 서남해안 지역의 해조자원 실태에 관해 조사한 결과는 다음과 같다. 1. 해황특성(해류, 탁도, 수은, 수심 등)을 기초로 하여 볼 때 이 해역은 거문도와 소흑산도 여서도를 포함하는 외양역과 나머지 내만역으로 구분되며, 내만역은 건조시 간석지가 노출되는 서해와 남해의 내만지역과 안마군도에서 진도 남단에 이르는 도서지역, 대흑산도와 인근도서지역, 보길도에서 돌산도에 이르는 남해 중서부의 도시지역으로 세분된다. 2. 전남해역에 생육하는 것으로 확인된 해조류는 남조류 28종, 녹조류 59종, 갈조류 85종, 홍조류 271종 등 총 443종으로 한국산 해조류의 66%가 생육하고 있어 해조상이 매우 풍부함을 알 수 있다. 3. 해조류의 종다양성 및 종풍부도는 외양역으로부터 내만역으로 갈수록 낮아지며, 공단매립이나 생활하수 및 공장오폐수의 유입이 많은 곳일수록 종다양성의 감소현상은 심화되고 있다. 또한 내만역으로부터 외양역으로 갈수록 C/P, R/P, R+C/P값이 모두 낮아지는 경향을 보여 우리나라의 해조식생을 위한 종조성비율의 적용이 해안별로 달라져야 함을 시사해 준다. 4. 해조류의 수직분포양상은 지역에 따라 약간의 차이가 있기는 하지만 대체로 조간대 상부로부터 불등풍가사리, 애기우뭇가사리-지충이, 구멍갈파래, 톳- 작은구슬산호말, 개서실, 참보라색우무, 모자반류로 이어지는 특징을 보였으며, 파래류와 김류는 하계와 추계에 그리고 불등풀가사리는 가을에 뚜렷한 기소현상이 관찰된다. 5. 전남지방의 해조류 생산량은 전국의 78.2%를 차지하여 이 지역이 해조자원의 보고임을 시사해 준다. 종류별로는 미역, 김, 톳, 파래 등이 주종을 이루고 있고, 계절별로는 겨울과 봄에 주로 양식을 통해 대량 생산되어지고 있다. 전남지방의 경우 전체 해조류 생산량 중 51.4%만이 계통판매되고 있어 수산물 유통시설의 확대와 현대화가 필요하다. 6. 특정해조류(김, 미역)의 대량생산과 이에 따른 품질저하로 어가수지의 악화가 우려되고, 밀식과 내만 양식어장의 노화 그리고 오염에 의한 연안 생태계의 황폐화가 우려되므로 품종별 조정을 통한 효율적인 어업수행과 연안생태계의 보존대책이 절실하게 요구된다. 아울러 이 지역의 해황특성에 적합하여 잘 생육하고 수출 및 자원으로 활용이 가능한 대표적인 해조류는 모자반, 톳, 우뭇가사리, 풀가사리, 불등가사리, 꼬시래기를 들 수 있다. 7. 전남해역에 생육하는 해조류 중 잠재적 자원으로 활용이 가능한 종류는 녹조류 23종, 갈조류 22종, 홍조류 60종 등 총 105종이다. 이들은 식용, 약용, 산업용, 동물사료용, 비료용 등으로 활용 가능하나 식용 이외에는 거의 활용되지 못하고 있다. The state of marine algal resources in west-southern coast of Korea was investigated. This coast is divided into the open sea(including Soheuksando, Geomundo and Yeoseodo) and inland area(including other regions) by sea water temperature and other hydrological conditions. And inland sea area is divided into four sections by depth, turbidity and sea water temperature. A total 443 species is list up to now in this coast ; these consist of 28 blue-green, 59 green, 85 brown and 271 red algae. The diversity and abundance of species was relatively low, C/P, R/P, R+C/P ratio higher in inland area. Algal vertical zonation in this area is characterized by Gloiopeltis furcata, Gelidium divaricatum - Sargassum thunbergii, Ulva pertusa, Hizikia fusiformis-Corallina pilulifera, Chondria crassicaulis, Symphyocladia latiuscula, Sargassum spp., in turn. Marime algal productivity in Cheonnam amount to 78.2% of total products. These products, mainly yielded in winter and spring, are composed of Undaria pinnatifida, Porphyra spp., Hizikia fusiformis and Enteromorpha spp. Overproducton and quality inferiority of specific cultured species such as Undaria, Porphyra, aging of culture farm, and desolation of coastal ecosystem are regarded as obstructive factors for the increase of fishery income. Although the potential algal resources of 105 species occur in this coast, they have not been utilized except for food.

시간적으로 변화하는 환경에 대한 유전형들의 서로 다른 반응은 개체군내에서 그러한 유전자형들의 장기적인 유지활동에 일조 할 수 있다. 우리는 생물형들의 계절의존 적합도의 구성요인들이 개체군내에서 유전적인 다양성을 유지하는데 도움이 되는지를 조사하였다. 봄, 여름, 가을 및 겨울로 구분된 4계절 동안 채종된 종자들이 온도처리에 따라 실험되어졌다. 발아세와 발아율의 차이는 앞선 연구들의 결과와 같이 생물형중에서 발견되었다. 생물형들 사이에서 나타나는 생태적인 차이들은 온도처리에 대해 생물형적 특성이 나타났다. 시간을 통한 대조적인 계절적 형성의 생물형들의 유지는 만약 장기간 적합도의 값이 비슷하게 유지된다면 기대 되어 진다. Differential response of genotypes to temporal environmental heterogeneity may contribute to the long-term persistence of those genotypes within a population. We tested whether season-dependent fitness components of biotypes could be responsible for the maintain of genetic diversity within a population. Seeds collected for four season (spring, summer, autumn, winter) were experimented to temperature treatments(15℃, 20℃, 25℃, 30℃). Differences in germination velocities and rates were found among the Taraxacum officinale biotypes supporting previous findings. Ecological differences among biotypes were also detected with biotype-specific response to the temperature treatments. The persistence of biotypes of contrasting seasonal performance through time is expected if long-term fitness values remain similar.

It is so difficult to know about the course of non-point source that only few people studying. This is the reason why we did not get good result in water-treatment frequently. Point and non-point source study must be balanced. This report have this intention. Summer is rain season in Korea so we have many problem in water quality. Bad quality originated from agricultural field, non-point source, that flow nutrients, agricultural chemicals, weed chemicals and etc. In this report provide the basic data of non-point source study on river of Haenam Area. Three point that we research is near Bok-pyoung, Kil-ho and Eo-seong bridge at 1999. 7. 5 ∼ 7. 12. Resulted: BOD, COD, SS, T-N, NH₃-N, NO₃-N, T-P, PO₄-P, Alkalinity decrease afterraining, dilution, much amount of water quantity made it. Agricultural section that major non-point source effluent high waste concentration at first stage, but dilution made lower at last. so it is needed that non-point source water storage for improve first stage wastewater at the lower part of a river. And continuous study about non-point source outbreak reason by waste effluent quantity data that made water quality and quantity research after division of the land useness near the river is needed, too.

This study makes physical structure design criteria of sediment basin which can enhance the trap efficiency of the sediment based on existing researches related to the sediment basin, examines the physical structure of the sediment basin at Buju mountain, Mokpo city which causes the environmental problems like the erosion and sediment outflow due to the excessive development, compares and examines it to the design criteria and explores the problems. As the volume ratio is greater, the sedimentation ratio is increased and as the area ratio is less the sedimentation ratio is increased. The length to width ratio of sediment basin is required at least 2:1 or 3:1 avoid dead storage area. The depth of the sediment basin is determined by the duration of construction period and it can be calculated by estimating the accumulation of sediment during the construction period. The sediment basin depth is required at least 60cm to avoid resuspending of sediment. As a result of the analysis of the existing sediment basin, the sediment basin C has the greatest volume ratio as 1.48 and it can be expected the most trap efficiency of sediment, followed by sediment basin B, A, E, F and sediment basin D is least as 0.08 and it can be expected the least trap efficiency of sediment. The sediment basin C has the least are ratio as 11.96 and it can be expected the most trap efficiency of sediment, followed by sediment basin B, S, E, F and sediment basin D has the greatest area ratio as 145.33 and it and be expected the least trap efficiency of sediment. It is consistent with the trend of volume ratio. The length to width ratio. The length to width ratio of the sediment basin is less than 1 and it becomes a problem at sediment trap efficiency among physical structure elements of sediment basin, The depth of sediment basin needed for the accumulation sediment was good in all.
