| 摘要: |
| 不同季节底梄生物数量的动态由其组成种的种群特点所决定。在一些生命周期短(一年左右)、生长速度快(新生个体当年可以长成)的种处于优势的情况下,生物数量的季节变化就比较显著;而生命周期长、其种群由多个年龄组的个体构成的种占优势的情况下，一年之中种群数量就相对稳定。另一方面,底栖生物数量的急剧改变又决定于经济种的捕食活动和优势种的生物学过程。台湾海峡系经济鱼、虾类的集中分布区,尤以上升流区范围内的集群最密集。为了便于深入研究上升流与经济鱼、虾类资源的关系,本文着重探讨上升流范围内底栖生物数量的动态特点。 |

| Abstract: |
| Analysis of two series of nine each grab samples, obtained in various months from May,1983 to May, 1984 in stations 5206, and 5207, revealed the patterns of benthos quantity dynamics in an upwelling area in Taiwan Strait. The diversity index (H’) and evenness index (J’) of various benthos samples were all more than 3 and 0.7 respectively. Those indicate some of benthos community structure are similar to lower latitude waters. But there are two and five species being dominant respectively, Which show other community structure is similar to midle and higher latitude waters. On the other hand, the similarity index (S) of pairs of samples taken in warm season months were all more than 0.4 and this is also in the cold,but ones taken in warm and cold season months were lower than this, indicating the difference in community structure in warm and cold season. |
