        摘要：With the results of numerical modelling of the tide and tidal current this paper discusses the characteristics of tidal mixing in the Bohai Sea, the Yellow Sea and the East China Sea which shows that in the area with significant diurnal tidal current the Simpson-Hunter stratification parameter K, calculated by using quasi-maximum current speed rather than amplitude of M2 constituent tidal current can represent better the characteristics of tidal mixing. Analysis of the relation of the distributions of the bottom cold water (Yellow Sea Cold Water Mass) in the cooling season with tidal mixing showed that the bottom cold water can exlst longer in the northern and southern weak tidal mixing sreas of the Yellow Sea than other areas because of minimum tidal stirring there. The efficiency of wind and tidal mixing in the western part of southern Yellow Sea are also discussed.

        摘要：Based on temperature and salinity data gathered from 1963 through 1986 in the Yellow Sea and the East China Sea in summer, the distributional characteristics of the inverse structure of the temperature and salinity and its formative causes are analysed in this paper. Some results show that (1) the inverse structure in summer can be found in three regions, the area of the Zhejiang Coast upwelling, the area of the cold eddy in the northern part of the East China Sea and the area of cold water mass in the southern Yellow Sea, (2) the inverse structure in above three areas can be separately caused by the wind, the vertical circulation in the area of the cold eddy,and the northward extension of the Huanghai warm current water which is warmer and more saline in bottom.

        摘要：Using 1974-1982 hydrometeorological data on the Bohai Sea, Yellow Sea and the East China Sea.and the bulk method of Kondo,the diabatic bulk transfer coefficients in summer and winter were estimated and diatributive features of bulk transfer coefficients for sensible and latent heat and momentum fluxes at the sea surface in these areas were analyzed. The results showed that the bulk transfer coefficients in winter were greater than those in summer and also suggested that 103CD≈1.46 to 1.53；103CH≈1.25,103CH≈1.16 in the Bohai Sea;103CE≈1.25 to 1.36 in summer,and that 103CD≈1.62 to 1.69;103CH≈1.41-1.46;and 103CE≈1.46 in winter.The heat balance over the sea surface was approximated by empirical formulae.

        摘要：After investigation and analysis of tidal current and COD in Shijiu. Bay,the ADI method based on two-dimensional nondinear tidal wave equations is used to simulate the space-time distribution of the tidal current and matter concentration fields there after the 1st Shijiu Harbour work is finished.Then the probable space-time variation of tidal current and matter concentration caused by the 2nd to 4th harbour works are forecasted.The results show that the 2nd to 4th harbour works will greatly change the water dynamics of Rizhao Harbour, that with the extension of the mole and breakwater, the current direction along their respective two sides, and the tidal current speed,will be changed,and that eddies will occur around them. This will make the COD concentration increase rapiddly along the coast of Shijiu, and water quality will worsen and not be up to the 3rd class seawater quality standard of our country.

        摘要：In the coastal plain of Laizhou Bay, the thickness of Quaternary sediments increases from the south to north and from east to west. The center of sediments is in the coastal area of the Xiaoqing River mouth. The contribution of marinebstrata is very different in the west and east, showing differences between the relief and sea level height during different stages. There were two transgressions east of the Weihe River in 40, 000 a. B P, three west of it in 100, 000 a.B P. and five in the west of Laizhou Bay in 200, 000 a. B P.. The Ostracean reefs of China in the middle Holocene were discovered for the first time in Xinhe of tbis region. This leds to the discovery of the Xinhe Paleo-coastline, high sea level in the middle Holocene and warm Paleo-marine environment so that the ancient Ostracean reefs have become the important indicators for resonstruction of the ancient coastal environment. The underground Quaternary littoral facies brine and widely distributing loess are due to the special geographical environment. Conversely, they are indicators of the environment in the ancient climate. The loess platean reflects the dry climate in this region in late Quaternary. During the cold climate period of late Pleistocene. in this region, there were forest-grassland vegetation and animal groups existing in the outer surroundings of the ice margin. This period is the important stage of the ancient environment evolution in Shandong Peninsula.

        摘要：This paper deals with the distribution features of SO2-4，,ΣS(-II), S2- in seawater and sediment interstitial water, and diffusion flux of sulfur near the sediment-seawater interface in the Huanghe River Estuary's northern district. SO2-4，,ΣS(-II), and S2- concentrations in seawater are high inshore and low offshore, and the vertical changes are small, In sediment interstitial waters SO2-4 concentrations are low inshore and high offshore; in surface interstitial waterΣS(-II), and S2- concentrations are high inshore and low offshore; in 30-40cm layer of interstitial waters, ΣS(-II), and S2- are low inshore and high offshore and change strongly in vertical distribution. In general, SO2-4 tends to decrease, ΣS(-II), and S2- tend to increase in vertical profiles. SO2-4 diffusion near the sediment-seawater interface is from overlying water to sediment, and the diffusion flux is -1.614mmol/㎡.d inshore, but HS-and S2-. diffusions are from sediment (interstitial water) to overlying water, and the diffusion flux of HS- is 8.950 μmol/㎡.d offshore。

        摘要：This paper discusses 1983-1986 space-time distributions of NO3-N,NO2-N,NH4-N,PO4-P and SiO3-Si,their origins and the relationships between them and other environmental factors.High concentrations of inorganic N(particularly NH4-N) and PO4-P were found in eastern and northeastern waters and low concenteations in the middle waters of the Jiaozhou Bay,bay mouth and outer bay waters,indication clearly that the high concentrations of inorganic N and PO4-P were mainly from the output of industrial and residential area sewage in the east coast.The concentration of NH4-N(yearly average,5.0-10.2μmol/L during 1983-1986) was much higher than NO3-N(yearly average,1.1-2.5 μmol/L during 1983-1986) in the Jiaozhou Bay seawater, and the higher concentration of NH4-N(about 72 percent of total inorganic N) was the main form of inorganic N in the seawater. The atomic ratio between NO3-N and PO4-P (monthly average, 1. 4-16. 1, yearly average, 5.8 in 1985) was much lower than that between total inorganic N and PO4-P (monthly average, 9.3-60, yearly average,19.4 in 1985). It showed the system of NH4-N,NO2-N and NO3-N was not thermodynamic equilibrium. The concentration of SiO3-Si was lower (monthly average, 0.47-5.7 μmol/L, yearly average 2.7μmol/L) and could not be detected at some stations in some mouths.It was possible that low concentration SiO3-Si sometimes limited the growth of phytoplankton.

        摘要：This paper details the comparative anatomical studies on Chinese oysters. According to the presence or absence of promyal chambers and the connections between the body and the gills, Chinese oysters can be divided into three types and subdivided into six groups. Type 1, with left and right promyal chambers, including one group; Type 2, with right promyal chamber only, including four groups;and Type 3,without promyal chamber, including one group. The evolution trends in the digestive, nervous, circulatory, and"other systems, are discussed on the basis of anatomy, and the evolution through the living oysters is suggested. Many new soft part characters are found, and some are first used in oyster classifications. The world-wide confusions in species of Hyotissa, Parahyotissa, Saccostrea and Crassostrea are clarified to some extent.The old problems in identifying Chinese oysters are solved this time. One new monotypic genus Talonostrea and its species T. talonata, which are very important in the evolution lines, and a newly recorded species Alectryonella plicatula is described. The 20 proviously species are now re-identified as 15 species(Hyotissa hyotis, Parahyotissa imbricate,P.sinensis, Lopha cristagalli, Dendostrea folium, D. crenulifera, Alectryonella plicatula, Talonostrea talonata, Crassostrea gigas, C. rivularis, Crassostrea sp. Saccostrea cucullata, S. echinata, Planostrea pestigris, and Ostrea denselamellosa), belonging in two families, Grypheidac and Ostreidae, and four subfamilies, Pycnodonteinae, Lopheinae, Crassostreinae and Ostreidae.

        摘要：This paper presents the results of the 1987 and 1992 ecological studies on the macrobenthic community in the rocky coastal waters off Ling Shan Island.In the two surveys 49 species of macrobenthos were collected with scuba.They included seaweeds (9), seagrasses (1), molluscans (18), echinodermates (7),crustaceans (10) and other invertebrates (4). Zostera marina, Asterina pectinifera and Chlorostoma rustica were dominant species in these two surveys. Hemicentrotus pulcherrimus was abundant in 1987, but its number decreased in 1992. The number of Stichopus japonicus and Haliotis discus hannai decreased more remarkably in 1992 than 1987, because of. increased. over-fishing. The biomass of macrobenthos was high, being X=740 g/㎡. The biomass of seaweeds, echinodermates and molluscans were 538.1 g/㎡, 181.5 g/㎡ and 19.3 g/㎡ respectively and constituted 72.7%, 24.5% and 2.6% of the total biomass respectively.The biomass of other group was lower.
