Seasonal change of total bacterial numbers were estimated in Daechung Reservoir from September, 1998 to August, 1999 and environmental factors which affects total bacterial numbers were estimated. Total bacterial numbers ranged between 1.2 and 19.0×10 exp (6) cells/㎖ and averaged 6.9 ×10 exp (6) calls/㎖. Bacterial numbers changed dynamically with season. The bacterial numbers were highest in July and showed peaks in April and July in sites studied except for the HOE(Hoenam site). In the HOE(Hoenam site), total bacterial numbers increased ove the period of March∼August. The correlation coefficient between bacterial number and chlorophyll a(<200㎛) was r=0.72(p<0.05) at the MAN(man site). Total bacterial numbers in Daechung Reservoir was diversely changed by the seasonal variation of several environmental quality parameters.

대청호에서 세균군집의 생태학적 역할을 조사하기 위하여 대청호 본 댐과 대전 취수탑의 중간 지점인 대청호의 만입부 지점에서 1998 9월~1999년 8월까지 DAPI 염색법으로 수심에 따른 총 세균수를 조사하였다. 조사지점의 수표면, 수심 5m, 10m, 15m, 및 25m에서 각각 채수하여 총 세균수를 측정하고 이화학적 수질요인과 총 엽록소 α의 농도를 측정하였다. 총 세균수는 표층수에서 1.6~17.0x10^(6) cells/ml, 수심 5m에서는 2.3~11.0x10^(6) cells/ml, 수심 10m에서는 1.2~1.4.0x10^(6) cells/ml, 수심 15m에서는 1.4~15.0x10^(6) cells/ml, 그리고 수심 25m에서는 1.4~13.0 x10^(6) cells/ml이었으며, 본 조사에서는 4월경부터 수온 증가에 따라 표층수의 총세균수는 증가하기 시작하여 7월경에 최대에 도달하였고, 이때 수심이 깊어질수록 총세균수는 감소하는 경향을 보였다. 각 수심에서 총세균수와 총엽록소 α량 및 이화학적 수질요인과를 관계를 논의하였다. To define the ecological roles of bacterial community in Daechung Reservoir. Vertical variation of total bacterial numbers were estimated at MAN site for one year with DAPI staining.The bacterial numbers were counted, environmental factors were monitored at the surface, -5m, -10m, -15m and -25 m of MAN site and tried to explain the vertical bacterial numbers with environmental factors. The bacterial number was 1.6~17.0 x10^(6) cells/㎖ at the surface, 2.3~11.0 x10^(6) cells/㎖ at 5 m depth, 1.2~14.0 x10^(6) cells/㎖ at 10m depth, 1.4~15.0 x10^(6) cells/㎖ at 15m depth and 1.4~13.0 x10^(6) cells/㎖ at 25m depth. The Mean bacterial number at the surface was more that those at any other depth. The explanation of the vertical total bacterial numbers with environmental factors were suggested.
