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.

任炳善 木浦大學校沿岸生物硏究所 1984 沿岸生物硏究 Vol.1 No.1

Physicochemical properties of saline soils with soil depty were determined in Samho-myun at March 1 in 1984. Soil pH was variable in upper layer of soil and relatively constant in lower part. Water content of soil showed the lowest value at surface soil and increased with soil depth. On the other hand, electric conductivity and sodium content decreased progressively with the increase of water content through soil. profile. Electric conductivity and sodium content of suface soil were 2 to times as high as those of subsoil. Concentration of available phosphorus was increased with soil depth due to it's leaching through soil profile. Total nitrohen of soils showed relatively side range of 0.6∼2.8㎎/g and were affected by vegetation of stand. Sodium content of surface soil was increased as function of distance from inland, but decreased near the site of the shoreline. Comparing physicochemical properties among stands, soil pH, water content, electric conductivity and concentration of sodium and available phorphorus were lower in salt marsh of Yongang-ri than in reclaimed lands of Sanho-ri and Nabuldo.

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.

These studies had been carried out to investigate the characters of 4 streams as Gomakweon chon, Hampyeong chon, Sampo chon and Youngam chon and compared with the water quality in the downstream of Youngsan River at the period of Aug. 29 to 30 1996. The average paddy areas are 43%, forestry areas are 42.3% of down streams. Livestocks of cattle, hog and chicken are 42,160, 24,269 and 909,658 head. The amount of pollutant loading of BOD, SS, T-P and T-N in the Gomakweon chon is most higher as 15,240, 96,605, 1,350 and 2,565 kg/day, in the Sampo chon is most lower as 9,599, 36,160, 1,133 and 1,582 kg/day. Total amount of pollutant loading was lower in the Sampo chon which is a small area of the watershed, higher in the Gomakweon chon which is a large area of the watershed. To compared with water quality in the downstream of Youngsan River, the watershed areas of Gomakweon chon and Hampyeong chon are smiliar to as 216km and 200km, but water temperature, dissolved oxygen, conductivity, salinity, pH, turbidity, N-NH_3^-, N-NO_2^-, and N-NO_3^- of Gomakweon chon are appeared lower. To compared with Hampyeong chon and Youngam chon, N-NH_3^-, N-NO_2^-, N-NO_3^- and PO_4^- of Youngam chon was appeared 2-3 fold lower.

임병선,이오형,이건형 木浦大學校沿岸生物硏究所 1988 沿岸生物硏究 Vol.5 No.1

The physicochemical properties of soil and the distributions of both soil and marine marine microorganisms of Sohuksan-do, Chonnam were investigated on 22th of May, 1988. The results were as follows: 1. The physicochemical properties of soil 5. investigated sites revealed their pH values ranged 5.0-5.9(mean, 5.52). The values of electroconductivity, organic matter, total nitrogen, and water content were in the range of 140-190 ㎛ho/㎝ , 9.8-18.8%, 1.25-3.62㎎/g , and 27.2-46.5%, respectively. 2. Distribution of soil microbes The total count of bacteria, fungi, and actinomycetes were in the range of 3.0 -8.8 ×10??cells/g soil, 0.7-1.5 ×10??cells/g soil, and 2.0-2.8 ×10?? cells/g soil, respectively. Bacteria occupied about 64.2% of total population, and fungi 9.9%, actinomycetes 26.0%, respectively. Of the total count of each group, cellulolytic bacteria occupied about 13.7% of total bacteria, and celulolytic fungi, about 49.8%, cellulolytic acvtino-mycetes, about 12.2%, respectively. It was worth noting that cellulolytic fungi occupied a large proportion of the total count of fungi, meaning active progress of cellulose decomposition in this area. 3. Distribution of marine microbes The popolarion density of marine bacteria was found to be in the range of 1.07 -4.77 ×10??cells/㎖ at the surface layer, 1.02-7.77 ×10??cells/㎖ in the middle layer, and 2.53 6.58 ×10??cells/㎖ at the bottom layer, respectively. These results showed tendency of higher density at the euphotic zone. In caseof physiologically characteristic bacteria, the population density of proteolytic bacteria was higher than that of either lipolytic or amylolytic bacteria, meaning independence of this area from incorporation of nutrients from outside.
