崔範勳 西原大學校 1979 西原大學 論文集 Vol.8 No.-

Up to now, we have investigated Maeng-Ja-Jip-Ju(孟子集註) which is called Mixed Ku-Kyeol and if we summerize accomplishment studied about Ku-Kyeol in academic circles, borrowed character list which is used as follows can be made. As this, I think that the outline of Ku-Kyeol representation style appeared on the whole and announced that borrowed characters that seem to look on the Ku-Yeok-In-Oang-Kyeong(舊譯仁王經) does not include. The general principles include meaning borrowed character of fifteen letters and the representation of eighty six syllables that are made borrowed word of one-hundred thirty letters is possible. To represent a lot of cases, ending and suffix do not seem to be inconvenient, but it is true that unreasonableness follows representation of the national language syllable of single sound with restricted Chinese sound. As an example, the representation of intermediation vowel is so difficult that it is obscure and it is a remarkable weak point that phonetic representation of different condition does not include represential vowel case. Besides, the representation of aspirated sounds, fortis, and dipthong belongs to difficult point, in honorific way, the representation of is more difficult problem. This problem does not remain unsolved. In accordance with the discovery of new data and more minute study way, the specific grevity of value of Ku-Kyeol is large in reconstruction of ancient native language.

In this study limnological characteristics of Lake Juam was surveyed from June 1993 to May 1994 in order to provides important information regarding water resources. Seschi disc transparency, epilimnetic chlorophyll a(chl-a), tatal nitrogen(TN), total phosphorus(TP) concentration and primary productivity were in the range of 2.0~4.5 m, 0.9~13.6 mgChl/㎥, 0.78~2.32N/l, 11~56 mgP/㎥, 270~2,160mgCm^(-2)day^(-1), respectively. On the basis of TP, Chl-a and Secchi disc depth, the trophic state of Lake Juam can be classified as mesotrophic lake. The phosphorus inputs from non-point sources are concentrated in heavy rain episodes during the monsoon season. As a result, phosphorus concentration are higher in summer than in winter. TP loading from the watershed were estimated to be 0.9 gPm^(-2)yr(-1), which correspond to a boundary of the critical loading (1.0 gPm^(-2)yr(-1), which correspond to a boundary of the critical loading (1.0 gPm^(-2)yr(-1)) for eutrophication. From the results of the algal assay, both phosphous and nitrogen act as limiting nutrients in algal growth. The seasonal succession of phytoplankton community structure in Lake Juam was similar to that observed in other temperate lakes. Diatoms(Asterionella formosa and Aulacoseira granulata var. angustissima) were dominant in spring and winter, cyanobacteria (Microcystis aeruginosa, M. sp. and M. viridis) were dominant in warm season. The organic carbon, nitrogen and phosphorus content of lake sediment were 9.5~14.0 mgC/g, 1.01~1.82 mgN/g, and 0.51~0.65 mgP/g, respectively. The allochthonous organic carbon loading from the watershed and autochthonous organic carbon loading by primary production of phytoplankton were determined to be 1,122 tC/yr and 6,718 tC/yr, respectively. To prevent eutrophication of Lake Juam, nutrient management of watershed should be focus on reduction of fertilizer application, proper treatment of manure, and conservation of topsoil as well as point source.

소양호에서 인의 존개 형태별 분포에 관하여 : The Distribution of Phosphorus Fractions in Lake Soyang

김범철,허우명,황길순,김동섭,최광순 江原大學校 附設 環境硏究所 1996 環境硏究 Vol.13 No.-

The distribution of phosphorus in Lake Soyang from January 1985 to August 1992 was surveyed by the measurement of soluble reactive phosphorus(SRP), total dissolved phosphorus(DTP), and total phosphorus(TP) concentration. SRP concentration was in the range of 2~7㎎/㎥ in epilimnion, and 4~200㎎P/㎥ in hypolimnion. The vertical distribution pattern of SRP showed a large difference with the season. SRP concentration decereased during the growing season of phytoplankton in the epilimnion of Lake Soyang and increased in hypolimnion during the oxygen depletion. Higher concentration near the bottom implies they are diffused from the bottom sediment where organic particles are settled and degraded. SRP, DOP, POP and TP concentration was higher in the meralimnion of Lake Soyang in rainy season It might be related with storm runoff. General trend of TP variation is that the TP concentration of water column is increasing substantially from yeat to year. TP concentration in the surface water increased from 5㎎P/㎥ at 1985 to 20㎎P/㎥ at 1992.

Seasonal and vertical distributions of dissolved and particulate organic carbon were investigated from May 1995 to March 1997 in n deep mesotrophic reservoir, Lake Soyang, POC contentrations at the dam site ranged from 0.1 to 1.8 mgC/L and DOC concentrations ranged from 1.4 to 4.9 mgC/L. POC concentrations in the surface layer were higher in the season of cyanobacterial bloom, July to September. High POC was observed at the depth of 30 to 60m after storm runoff in summer monsoon season. Turbid storm runoff formed intermediate current laden with much particulate materials from terrestrial sources. The vertical and seasonal variation of DOC was smaller than POC. Higher DOC was observed near the lake bottom which implies sedimentation and degradation of much organic detritus at the bottom. The ratio of DOC : POC varied from 2 to 60, and the ratio was lowest in September 1995 when algal density was highest. DOC : POC ratio of the main inflowing river, the Soyang River, varied from 1 to 10, and the ratio was low in storm runoff when the POC concentration was high.

The limnological survey of Lake Okjong was conducted for one year from June 1993 to May 1994 on the monthly basis. The loading of phosphorus, nitrogen and organic carbon from the watershed into the lake were monitored at the main in flowing sites. Secchi disc transparency , epilimnetic chlorophyll a, total nitrogen, total phosphorus concentration and primary production were in the range of 1.3~4.H m, 2.4~ 18.7 mg Chl/m³. 1.25~2.87 mg N/l, 7~65 mg P/m³, 325~2,113 mg C/m²/day, respectively. TN/Tl atomic ratio varled from 129 to 443. N/P ratio decreased in summer because phosphorus concentration was higher than in winter, while nitrogen did not vary much. The seasonal succession of phytoplankton was distinct. In winter and spring, diatoms, Aulacoseira granulata var. angustissima and Aulacoseira italica were dominant while cyanobacteria, Microcystis sp.,M. ichthyovlabe, Phormidium sp. and P.valderianum var. tenuis were dominant in warm seasons. The dominant zooplankton species were Thertmocyclops taihokuensis in warm seasons while Boosmina longirostris were dominant in cold seasons. The organic carbon, nirtogen and phosphorus content of lake sediment were 8.0~14.8, 0.59~0.71, 1.14~1.87 ng N/g, respectively. The sediment of Lake Okjong can be classified as oligohumic based on C/N ratio. The total phosphorus loading from the watershed and fishfarm were estimated to be 2.7g P/m²/yr, which far exceeded the critical loading for eutrophication. The organic carbon loading from the watershed and primary production were determined to be 998t C/yr, 6,348t C/yr, respectively. Most of organic carbon was contributed by autochthonous primary production of phytoplankton. Trophic state of Lake Okjong can be classified as eutrophic

To investigate nutrient dynamics of the lake and fish community, both water and fish samples were collected at three different areas (dam site, upper inflowing and downstream of lake outfow) for one year from Sep.2004 to Aug.2005 During the experimental periods, mean concentration of chl, a in epilimnetic layer (0-5m) was 18.5mg^(-3) and transparency ranged from 0.3m to 2.4m, respectively. In nutrient, mean concentrations of TP and TN were 111 mgP m^(-3) and 4.4 mgN L^(-1), respectively. Based on the water quality standard suggested by U.S.EPA(*1976), the trophic state of Lake Doam was classified as eutrophic state. Total number of fish collected in Lake Doam was 9,600 indiveduals in 26 species of 6 family. Sixteen of Korean endemic soecies including H. mylodon, A. signifer, P. tenuicorpa occurred. O. mykiss as introduced fish was also found in Lake Doam. Dominant and subdominant species were P. herzi and Z. platypus that took about 34.6% and 22.5% of total fish composition, respectively. Six species including A. signifer. P. tenuicorpa. and R. kumgangensis were rare in Lake Doam. Pelagic typw of figh commonly occurred at upper regions, whereas benthic type was mainly domenated at downstream area. Therefore, pollution source inflowed from the upper regions did not seriously affect downstream area (Songcheon water system) due to the role of dam as pollutant barrier. In addition high appearance of Comat type of fish that si hybrid between gold fish (C.auratus) and C. auratus was found in the lake, It was unclear the reasons that high prorortion of mutant species apperared in the lake. Further more researches are required in this area.

In Korea most of nutrient tending into lakes is concentrated in stormy seasons. Phosphorus lording and transport of turbid storm runoff water was investigated in a reservoir, Lake Soyang, Korea. Concentration of phosphorus was measured at ten meter intervals on the monthly babe in dry seasons and biweekly in stormy seasons. The loading from drainage basin was determined by measuring total phosphorus (TP)concentration in the main in flowing stream, the Soyang River. Because total phosphorus concentration and flow rate of the Soyang River was high in flood period, most of annual phosphorus tending was concentrated in several sporadic storm runoff. In July of 181)8 phosphorus input was 418 tP/month. It was much higher than that in June, 6.0 tP/month. 10% of annual total phosphorus input was discharged through outlet during the period from ,lune to October. Turbidity was much higher(2~ 78 NTU) in stormy seasons than in dry seasons (1 ~ 9 NTU). Cold storm runoff laden with high turbidity and phosphorus flowed into metalimnion along the layer of same densify. Total phosphours concentration of intermediate turbid water ranged from 20 to 230 ?gp/m³. After stormy seasons high nutrient concentration was con-sistently observed at intermediate layer until autumn turnover. In autumn descending mixing depth caused increase of phosphorus concentration in the epilimnion.

The temporal and spatial distribution of water temperature was surveyed and simulated in a deep warm monomitic Reservoir. The great depth (maximum depth of 100 m) and wind-sheltered dendritic shape caused strong summer stratification, Turbid storm runoff during the summer monsoon formed a metalimnion of 20~40m thickness which was distinct from the clearer epilimnion and hypolimnion. The temperature distribution and the movement of density current were simulated by using the 2-dimensional hydrologic model CE-QUAL-W2. Model was calibrated with 1996 date and verified data from 1995-1999 by applying the same set of parameters and constants as in calibration. The model could simulate temperature profiles with excellent agreement. Simulation results of movement of the intermediate density current also satisfactory. It can be concluded that the CE-QUAL-W2 model is useful in the prediction of the temperature distribution and movement of density current in reservoirs, which implies merits for further employment in water quality simulation.

The longitudinal variations of water quality along the mainstream of the Nak-ding River from May 1994 to October was surveyed by the measurement of chl-orophyll a, total phosphorus, total nitrogen, dissolved inorganic phosphorus, nitrate-nitrogen, ammonia-nitrogen concentration, and secchi disc transparancy. Chl. a, TP, TN, DIP, NO_(3) and NH_(3)-N concentration was maintained at high level during the investigation period. And they also showed the peak after the input of Kumho River. Chl. a concentration was increased from 14.2㎎/㎥ in May to 95.2 in October. TP ane TN concentration was maintained always above 100㎎/㎥ and 3~4㎎N/l, respectively. TN/TP ratio were less than 16 from June to September with a few exceptions. Therefore, nitrogen is the limit-ing nutrient in the Nakdong River. Trophic states were in the range of eutrophic to hypertrophic, from 60 to80.

The autochthonous and allochthonous organic carbon loading were measured in Lake Soyang, to estimate the amount of carbon loading into the lake and the contribution of their sources to the lake's carbon loading. Autochthonous carbon loading was estimated from phytoplankton primary production with the extracellular organic carbon(EOC). Allochthonous loding was determined by measuring dissolved organic carbon(DOC) and particulate organic carbon(POC) concentration in the main inflowing Soyang River. Both autochthonous and allochthonous organic carbon loading were high during the summer, from July to September, and accounted for 43.2% and 71.7% of the annual loading, respectively. Primary productivity was elevated up to 1,000 mgCm^(-2)d^(-1)during summer and lowest in winter. EOC production from phytoplankton was also large in summer, resulting in a high DOC concentration in the lake water. Primary production of phytoplankton and allochthonous organic matter loading from the watershed contributed to 53.6% and 46.4% of total loading, respectively. The EOC production accounted for 4.4~21.2% of POC primary production, implying that EOC production of phytolankton must be considered in estimation of primary production.
