A PRELIMINARY ANALYSIS OF THE AQUATIC ENVIRONMENT OF THE SOUTH OF WEIHAI BAY

Yang Yuling; Wu Yongcheng (Institute of Oceanolology , Academia Sinica, Qingdao 266071 )  
Weihai Bay is situated in the northeast of the Shandong Peninsula, extending about 9 km in length from south to north and about 7km in width from east to west. Since 1989, owing to the increase in population and rapid development of industry, the south of Weihai Bay has been put into development and the pollutants discharged into sea greatly increased in quantity, thus causing the pollutants in local areas to exceed the standards and physical self-purification ability of the sea, and resulting in pollution.Based upon the observed tide and COD data, this paper discussed the pollution loading amount of the south of Weihai Bay by making use of the distribution of tide and the features of diffused materials calculated with a mathematical model. This paper also pointed out that the tide in western waters of Weihai Bay is fairly small and physical self-purification ability is so weak that the pollution loading amount in some inshore areas has already reached or approached to saturation. Hereafter, in discharging large quantities of sewage into sea from newly developed zones, it is more advantageous to select waters outside the bay where tide is relatively stronger to discharge the sewage into deep sea.
