| 摘 要： | 传统观念的底层流是指离底大于或等于２ｍ的海流。离底小于２ｍ的流场特征，至今研究甚少。近年来，随着养殖业的蓬勃发展，对其了解的需求愈来愈迫切。１近底层流观测全国海岛资源综合调查时，按“青岛市海岛办”的要求，在灵山岛西北侧适养区（水深１２ｍ）布设了一个近底层（离底２０ｃｍ）流观测站（３５℃４６＇Ｎ，１２０℃９＇Ｅ），连续观测１５昼夜。观测期间适逢１９９０年５号台风在江苏省北部登陆，该站测得１１．９ｍ／ｓ的风速。观测仪器使用国产ＨＪＬ１－１型印刷海流计。测流时将海流计悬挂于特制三角架中央，由潜水员精确…

| Abstract: | day serial near-bottom currents (at 20cm over Sea bottom) were measured in the northwest suitable breeding area near Lingshan Dao Island in order to study the potentials for the breeding environment. Statistical analysis is made for current speed frequency distribution besides harmonic analysis for these current data. The results show that the near-bottom current speeds mainly concentrate on the range of 6- 15 cm/s at frequency of 47 percent, the cumulative frequency at 25 cm/s reaches 86 percent, and maximum speed measured is 48 cm/s. |
