| 内容記述 | In order to clarify the mechanism of lake eutrophication, the authors have investigated the limnological characteristics of dammed Lake Ono, Ube City, Yamaguchi Prefecture, since 1981. As a part of the studies, the present paper deals with the catchment areas and the monthly retention time (τm) and the annual retention time (τ) of the lake. These retention times were calculated from the storage and the inflow of the water during 1966-1983. The results can be summarized as follows: 1) The catchment area is 320.2 km2, of which 51.8% and 32.3% are occupied by River Kotou division and R. Oota division, respectively. This area camprises a population of about 18,600 and about 28.9 km2 of the rice field. Akiyoshi limestone group spread over both the divisions is 19.6% of the catchment area. 2) The maximum daily inflow was 436.6X 105m3/day, and the mean annual inflow was 0.368 km3/year. The inflow changed seasonally with larger values in summer and smaller ones in winter. 3) The great substitution of lake water occurred only in summer, with τm of less than 5 days. The mean values of τm got shorter to about 10 days in summer, while longer to more than a month in winter. 4) The annual retention times (τ) changed irregularly year by year, indicating mean value of 17.5 days during 1966-1983. 5) The eutrophication of this lake water would be largely effected by the inflow which is enriched with nutrients originated from the catchment area and also by the retention time which is not so short that phytoplankton population might be diluted out and not so long that nutrients might be depleted in the euphotic zone. | |||||
