다국어 초록 (Multilingual Abstract)

This paper aims to contribute to the increase of laver production with the scientific raising and management of laver, after examining closely the various surroundings of the inside ocean and the outside of Wan-Do, the central farming place of laver, physically and chemically and comparing and investigating the laver productivity of it.
As a result of investigating and studying many important factors thrice a year, that is, in the months of September, November an February from 1981 through 1983, I measured the follwing factors : water temperature, salinity, dissolved oxygen, pH, Nitrite-N, Phosphate-P, and transparency.
The results of study are as follows.
The change of water temperature in February 1982 Varied from 5.0℃ to 8.5℃and in February 1983 Varied from 6.5℃ to 8.5℃.
The Salinity in February 1982 fluctuated with in the range between 33.42‰ and 34.03‰ and in February 1983. fluctuated with in the range between 33.31‰ and 33.60‰.
~ pH in general showed a fluctuation between 7.89 and 8.1
The range of dissolved oxygen in 1981 was from 4.40㎖/ℓ to 7.22㎖/ℓ and in 1982, was from 4.20㎖/ℓ to 6.50㎖/ℓ.
The change of dissolved oxygen showed the maxium of 7.22㎖/ℓ in February 1981 at station 3, and a minium 4.20㎖/ℓ at station 3 in September 1982.
Transparency showed a fluctuation between 0.25m and 1.5m .
The change of Nitrite-N in 1982 or 1983, Varied from 0.19㎍-at/ℓ to 0.66㎍-at/ℓ
The phosphate-P in 1982 or 1983 fluctuated with in the range between 0.35㎍-at/ℓ and 1.08 ㎍-at/ℓ.
As a result of the study of the annual variation on oceanorgraphical factors of Wan -Do Coast Area, Water temperature, more than anything else, was showed up as having an important effect to the laver growth condition and the situation of laver production of the outside ocean was showed up better than that of the inside ocean.
I believe the cause of this is that the situation of seawater exchange of inside ocean is poor. And as a result of the overconcentration of laver farming place and the low phenomenon of water temperature etc., the production of laver is also poor, I think the quantity of laver production increased, for the inflowing quantity of landwater is little, the exchange of seawater is good, and the quantity of dissoled oxygen is abundant.
