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∼7mgP/m^3 in epilimnion, and 4∼200mgP/m^3 in hypolimnion. The vertical distribution pattern of SRP showed a large difference with the season. SRP concentration decreased 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 metalimnion 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 year to year. TP concentration in the surface water increased from 5mgP/m^3 at 1985 to 20mgP/m^3 at 1992.

The longitudinal variations of water quality along the mainstream of the Nakdong River from May 1994 to October was surveyed by the measurement of chlorophyll a, total phosphorus, total nitrogen, dissolved inorganic phosphorus, nitrate-nitrogen, ammonia-nitrogen concentration, and secchi disc transparancy. Chl. a, TP, TN, DIP, NO_3-N 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 increased from 14.2mg/m^3 in May to 95.2 in October. TP and TN concentration was maintained always above 100mg/m^3 and 3∼4mgN/l, respectively. TN/TP ratio were less than 16 from June to September with a few exceptions. Therefore, nitrogen is the limiting nutrient in the Nakdong River. Trophic states were in the range of eutrophic to hypertrophic, from 60 to 80.

시화호 인공습지의 유기물생산에 대한 갈대부착조류의 기여도를 평가하기 위하여 유입수의 수질특성이 다른 두습지(반월천습지와 동화천습지)에서 4월부터 10월까지 매월 부착조류의 1차생산력을 측정하였다. 부착조류의 현존량은 반월천습지와 동화천습지에서 각각 37~3,581 mgChl.a/m2surface stem(평균 655 mgChl.a/m2surface stem), 87~2,093 mgChl.a/m2surface stem(평균 527 mgChl.a/m2surface stem)의 범위로 동화천습지에 비해 반월천습지에서 큰 값을 보였다. 반면 부착조류의 광합성효율을 나타내는 동화계수(assimilation number; AN)는 반월천습지에 비해 TN/TP 비가 작은 동화천습지에서 높았다. 두 습지로 유입되는 유입수의 TN/TP비와 AN사이에서의 음의 상관(r=0.46)으로부터 부착조류의 높은 광합성효율은 낮은 TN/TP와 관련이 있는 것으로 사료된다. 부착조류의 단위면적당 일일 1차생산력은 반월천습지에서 307~2,473 mgC/m2/day, 동화천습지에서 756~2,096 mgC/m2/day로 두 습지 모두 여름에 높은 값을 보였다. 두 습지의 평균 1차생산력은 반월천습지가 부착조류의 현존량이 큼에도 불구하고 1,166 mgC/m2/day으로 동화천습지(1,467 mgC/m2/day)에 비해 낮았다. 이는 AN 값에서 알 수 있듯이 반월천습지의 광합성효율이 동화천습지에 비해 낮았기 때문으로 판단된다. 시화호 인공습지에서 갈대부착조류에 의한 연간 총 유기물생산은 300 tonC/year(습지 전체 유기물생산의 33%)로 습지내 유기물생산에 부착조류의 기여가 큰 것으로 나타났다. 습지내 과도한 유기물생산은 습지의 수처리효율을 저하시킬 수 있으므로 수처리용 인공습지의 관리에 있어서 갈대부착조류의 역할이 고려되어야 한다. To estimate the contribution of epiphytic algae attached on reed to organic matter production in constructed wetland, primary productivity by epiphytic algae was investigated in two sub-wetlands (Banweol and Donhwa wetlands) of the Sihwa Constructed Wetland (CW) with different chemistry of inflows. Chlorophyll a concentration of epiphytic algae was higher in the Banweol wetland (range:37~3,581 mgChl.a/m2surface stem, average:655 mgChl.a/m2surface stem) than the Donhwa wetland (range:87~2,093 mgChl.a/m2surface stem, average:527 mgChl.a/m2surface stem). In contrast, assimilation number (AN) representing photosynthetic activity was higher in the Donhwa wetland with low TN/TP ratio than the Banweol wetland. A negative correlation (r=0.46) was observed between TN/TP ratios of inflows and AN in two wetlands, implying that high photosynthetic activity of epiphytic algae may be related with low TN/TP ratio. The areal primary productivity ranged from 307 to 2,473 mgC/m2/day in the Banweol wetland and from 756 to 2,096 mgC/m2/day in the Donghwa wetland, showing high productivity in summer. Average primary production was lower in the Banweol wetland (1,166 mgC/m2/day) than the Donghwa wetland (1,467 mgC/m2/day), although the standing crop (as chlorophyll a concentration) was high in the Banweol wetland. This result may be due to the low photosynthetic activity of epiphytic algae in the Banweol wetland with high TN/TP ratio. The annual primary production (300 tonC/year) of epiphytic algae contributed 33% of the total production in the Sihwa CW. An excessive organic matter production in constructed wetland can negatively affect the efficiency of water treatment. Therefore, the role of epiphytic algae should be considered in management of constructed wetland for water treatment.

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.
