春季 錦江下流域의 水質 및 Diatom의 組成變化에 關하여 = Aa investigation on the composition quantity of Diatoms and Chemical contents in the below stream area of Gum River province in spring

다국어 초록 (Multilingual Abstract)

The monthly observation on the composition quantity of Diatoms and chemical contents was done at 7 stations in the below stream area of Gum River from April to June, 1978.
The total numbers of Diatom appeared by observation were 27 species ; neritic planktons(27), and oceanic planktons(2) and the composition organism of total diatoms was 1,600Cells/ℓ∼41,700Cells/ℓ.
The surface water temperature is 6.8∼20.8℃ at St. 3, 13.4∼23. 6℃ at St. 7 and the difference between two stations, was 3.3∼6.6℃, when, the temperature at St. 5∼7 was higher than 1∼4.
Transparency was 3.2m at St. 7, 11m at St, 3 and salinity was 29, 9∼32.2% at St. 1∼4, 28.4∼29.7% at 5∼7. The surface water of dissolved oxygen content was 5. 3∼6.2cc/ℓ, and bottom water was 5.3∼5.9cc/ℓ. The content of C.O. D was 0.49∼1.2ppm and it was higher in April than it was in May and June.
In case of NO2-N, the surface water was 0.3∼0.6㎍- at/ℓ, bottom water was 0.3∼0.6㎍- at/ℓ, and it's contents was the highest in June.
The contents of PO4- P was 0.03∼0.0㎍- at/ℓ, SiO2 was 5.9∼10.1㎍- at/ℓ and Ammonia-N was 0.8∼1.6㎍ at/ℓ.
