These days the surroundings around harbours are rapidly changing. Particularly in the age of Pacific Rim it is rather clear that the competition among the harbours in Northeast Asia region where are so many of worldwidely famous harbours might be intense. From 1980s on the industrialization and urbanization in the area of Kwang Yand-Bay, thanks to the regional development program, have been speedily under way. And in the year of 1987 the 1st development program of Kwang Yang-Bay container quay was started and is scheduled to be completed by the end of 1997. As the completion of the program it is expected that in 1998 the newly-opening Kwang Yang-Bay container quay on one hand will play a role in relieving the awaiting-time of vessels in Pusan Port, and on the other hand it will contribute to the balanced development of the country. In this context this thesis conducted Its study on the effect of the specification and facilities of a harbour, and especially on the effect on the regional economy resulted by the development & developmental static of Kwang Yang-Bay container quay. And progressively in the thesis the plan to provide Kwang Yang-Bay container quay with competitiveness was suggested.

In this study, properties of organic pollutans were examinated using simultaneous determination from Kwang-Yang Bay, Ka-Mac Bay, Ywan-Do, Hae-Nam, Young-Kwang, Mokpo in Southwest coastal sea. As result, score species of organic pollutants detected coastal sea during summer-winter season Many species of Phenols and Phthalates detected regardless of season in several point Especially, Pesticiides reprosented during summer between Kwang-Yang Bay, Ywan-Do, Hae-Nam. But in winter-season, many species of Aromatic compounds analyzed out in Kwang-Yang Bay. This results consider by pollution of organic pollutans from ship, flow hrbor, estuary, bay.

A series of physical oceanographic investigations of the circulation in the Kwang Bay' were carried out seven times from May 1974 to May 1975 every other month. The average water transports through the southern entrance of the' Kwang Yang Bay were approximately $1,014{\times}I0^6m^3$/half-tide in ebb current and $278{\times}10^6m^3$$405.6{\times}I0^6m^34/half-tide in ebb current, and $282{\times}10^6m^3 $/half-tide in flood current, at the maximum current intensity. The water from Seomjin River flows into the bay at an annual average rate of $84{\times}I0^6m^3$/half-tide, the rate being fluctuated from month to month from $6.0\times}10^6m^3 $to $11. 5{\times}I0^6m^3 $per half-tide.

Specimens of the sabellid polychaetes are exmined. They were collected in the Yellow Sea from Sept. 17 to Oct. 2, 1992 within the framework of Korea-China Yellow Sea Research Joint Program. Additional materials were also provided from the benthic samples collected from the subtidal shallow waters of the Kwang-yang Bay, Korea. Two secies of the genus Euchone (Polychaeta, Sabellidae), Euchone hancocki Banse and Euchone incolor Hartman are described and illustrated. This paper reports the first record of these two sabellids in Korea waters.

The appearence of organochlorine pesticide residues in some marinealgae, e.g. Sargassum thunbergii, Ulva pertusa, Codium fragile, and Enteromorpha linza, collected from various sites of Kwang Yang Bay, southern coast of Korea, was surveyed through the year from May 1974 to March 1975. The residues were found to appear in the order to July>September>May>November≒March≒January; $\alpha$-BHC>heptachlor epoxide>dieldrin>aldrin>endrin; and in the range of 0-93 $\mu\textrm{g}$/kg dry matter.

Simulations of CMAQ with the High-order Decoupled Direct Method (HDDM) for a 2010 June episode are applied to estimate the influence of local and neighborhood emissions on ozone concentrations in the Kwang-Yang Bay (KYB) area. In order to examine ozone response to reductions in $NO_x$ and VOC emissions from KYB and Gyeongsang, ozone isopleths are generated with the first and second-order sensitivity coefficients from HDDM simulations at three sites; Taein, Samil, and Gwangmoo. Simulations show that reduction in KYB $NO_x$ may increase ozone over the sites. On the contrary, $NO_x$ reduction from Gyeongsang may decrease ozone at the sites when transport of ozone and its precursors from upwind Gyeongsang is potentially high. However, VOC reductions from KYB and Gyeongsang are favorable to lower ozone over KYB. The study implies that emission reductions for both local and neighboring areas are likely more effective to bring KYB to ozone attainment.

The seasonal variations of the marine algal community were detected with quadrat method during May, 1974-May, 1975 at several stations in the Kwang Yang Bay. Considering the environmental factors such as salinity and water current, etc., and algal vegetation, the Bay was divided into 3 sections; Section I-Myodo and the adjacent area; Section II-Eomnamuseom and the adjacent area; Section III-inlet of the Bay from Odongdo, Yeosu. The dominant species, shown by 5-grades coverage and bimonthly investigations, appear in the order of Sargassum thunbergii(Jan.)>Chondria crassicaulis (Mar.)>Ulva pertusa(May)>U. pertusa (July)>U. pertusa and Gigartina intermedia(Sept.)> Sarg. thunbergii and Gelidium pusillum (Nov.) in Section I, and Sargassum thunbergii(Jan.)>Ulva pertusa and Hizikia fusiforme (Mar.)>U. pertusa and Sarg. thunbergii(May)>Chondria crassicaulis (Sept.)>Ch. crassicaulis (Nov.) in Section II. The members such as Srgassum thunbergii, Gelidium pusillum, G. divaricatum, Hizikia fusiforme, Carpopeltis affinis, and Chondria crassicaulis show the most luxuriant period of growth in winter (Nov.-Mar.), while Ulva pertusa shows the period in May. However, considering the dry weight of total vegetation, the most luxuriant period apperas in May and the poorest one in July. The total dry weight of the vegetation in Section II is about 3.2 times more than the one in Section I.

Vertical and horizontal distributions of chemical oceanograthic parameters were measured in Jinhae Bay in July, 1983. On the Masan-Gadeog section, high amounts of dissolved nitrates, ammonia, chlorophylla-a, and particulate carbon and nitrogen were observed in waters with low salinity. In the inner Masan Bay, high concentrations of dissolved ammonia and phosphates were shown. The C/N ratio in the surface waters was higer in the outer bay. Concentrations of dissolved inorganic nitrogen and phosphates in the surface waters seemed to be sufficient for red tides to occur.

In this study, we try to determine the distributive property in southwest coastal waters, such as K wang-yang bay, Ka-mak bay, Yeo-ja bay, Wan-do, Hea-nam, Young-gwang, and Mok-po, using simultaneous analytical method of 310 chemicals. The results were detected tens of the organic pollutants in sampling sites, and the major chemicals detected were CH type chemicals such as aliphatic, polycyclic compounds and were CHN(O) type chemicals such as aromatic amines, nitro compounds, In particular, pesticides were mainly detected in summer, phenols and phthalate esters were not seasonal effect. Also, a number of aromatic chemicals were detected in Kwang-yang bay, From the results of this study, we confirmed that it is mainly contaminated in summer and the pesticide chemicals are the major pollutants in southwest coastal waters.

The present study was based on the specimens collected from the Yellow Sea between Sept. 17 and Oct. 2, 1992 within the framework of Korea-China Yellow Sea Research Joint Program. Additional materials were also provided from the benthic samples collected from the tidal mud flats surrounding Inchon, Korea and from the subtidal shallow waters of the Kwang-yang Bay in the southern coast of Korea. Paraonid polychaetes have not been previously reported form Korea waters. Here, a total of six species in two genera are described and illustrated, and they are newly recorded in Korea polychaetous fauna : Cirrophorus furcatus, Cirrophorus armatus, Cirrophorus branchiatus, Aricidea (Aedicira) pacifica, Aricidea (Aricidea) wassi, adn Aficidea (Acesta) assimilis.
