台湾海峡南部漂浮植物

1988年6和11月,在台湾海峡南部用改进的Manta型漂浮生物网采集漂浮植物,共鉴定漂浮植物102种及变种.漂浮植物具有明显的季节变化,6月总数量高于11月.在平面分布上,6月漂浮植物密集区出现在台湾浅滩南部.11月密集区出现在台湾浅滩西部.漂浮植物数量具有一定的昼夜变化,最高值出现午后4时,最低值在午夜前后,与漂浮动物相反.讨论了漂浮植物与环境的关系,以及漂浮植物与漂浮动物的关系.

Phytoneuston in the southern Taiwan Strait

During the periocl of June and November 1988 samples were collected by the improved Manta neuston net at 18 stations in the southern Taiwan Strait. 102 species of phytoneuston are identified. Total individuals of phytoneuston in June are more abundant than those in November. In the horizontal distribution of phytoneuston, its dense area is located in the south part of Taiwan Bank in June, and in west part in November. The diel variations of phytoneuston are very obvious. The maximum abundance of phytoneuston occurred in the afternoon (16:00), but the minimum, at midnight. The relationship between the distribution of phytoneuston and environmental factors and relation ship between the distribution of zooneuston and environmental factors are discussed.
