Abstract
In order to analyze trophie states of lake and to suggest water quality control against eutrophication, we surveyed Dongbock lake from September, 1984 to November, 1984.
The Summary of the experimental resuite is followed:
(1) The Phytoplankton identifcation in this investigation was distributed in total 46 genera and 76 species.
(2) To appear a dominated alge was melosira, microcystis and Synedra in September.
(3) To appear a dominated alge was melosira, and microcystis, but cymbella, navicuea. and Mitzscbia was observed also in October.
(4) To appear a dominated alge was Asterionella, edlosira and microcystis in November.
(5) It was considerable fact that Onacystis, Euglena, Golenkia and Radiata usually appear in massive organic compounds exist phase was observed in these period.
(6) The content of dissolved oxygen (DO), Biological oxygen demand (BOD), chemical oxygen demand (COD), chloride Ion, Phosphorus, and nitrogen is ranged from 8.2 to 9.9(㎎/ℓ), 12 to 22(㎎/ℓ), 1.0 to3.0(㎎/ℓ), 5.9 to 11.9(㎎/ℓ) 45 to 70(㎎/ℓ) and 531 to 697(㎎/ℓ), respectively.
