中文摘要 | 本研究調查了臺灣西南海域七個不同區域的底棲甲殼類。除了瞭解各地生物相的組成外,以群聚分析的結果顯示影響甲殼類分布的因子主要為水深、底質特性及海域中水的交換程度(開放海域或半封閉海域),而水團的不同、廢水及漏油的污染則是影響底棲甲殼類分布的次要因子。以種-豐富度模式(species-abundance model)的分析顯示多數海域屬於中度污染,相較之下深海(200-260m)地區的環境則較穩定。 |
英文摘要 | The benthic crustacean communities at seven different localities in waters of southwestern Taiwan were studied and documented. We found that their compositions were mainly deter-mined by three factors: large-scale differences in depths of the water; the character of the bottom substrate; and the topography which influenced the circulation of water. Other envi-ronmental factors such as water mass movement, water pollution, and oil spills could also have influenced the community composition. Species-abundance model fitness test indicates that many of these communities are under medium-strength disturbance or stress from the environment. The community in the deeper ocean (200~260 m) is in a relatively stable con-dition. |
