摘　　要：灵山岛东临南黄海,西濒大陆,岸线曲折,地形复杂,因而这里的潮流除受黄梅潮波系统的影响之外,还明显地受到地形的影响。黄海潮波是由路经东海的太平洋潮波继续向西北方向传播形成的。由于受山东半岛和辽东半岛南岸的反射作用,在山东半岛南岸和成山头附近分别形成两个M_2分潮无潮点,另外在南黄海中部还形成一个K_1分潮无潮点。因此,黄海潮波则为颇具驻波性质的潮波。就灵山岛的地理位置而言,山东半岛南岸的M_2分潮无潮点位于其东侧大约80nmile处。Based on the observed current data of four stations and times obtained from the sea area nearby the Lingshandao island in August, 1986 and May, 1987, the characteristics of tidal current in the areaave analysed in this paper. The results show that the tidal current in the area basically belongs to the irregular semidurnal tidal current, M_2 constituent of tidal current is of the properties of reciprocal current, and residual flow is caused by both effects of the Huanghai Sea Coastal Current flown from the northern region and the topography of this area. In addition, rising tidal current goes south-west but ebb tidal current goes northeast in this area, so the outside sea Water basically occupies the researched area and it is difficult for the water of the Jiaozhouwan Bay with plentiful nutrints to affect the water here. So the nutrients in the sea area nearby the Lingshandao island is not too plentiful.
