中街山列岛底栖海藻生态的初步研究

本文报道了1986年7月至1988年10月在浙江北部中街山列岛潮间带进行的海藻定点定量调查结果,已鉴定底栖海藻94种。海藻组成以亚热带性与暖温带性种类占优势。区系性质与台湾暖流对本区的影响有关。底栖海藻的种类组成、垂直分布及生物量均存在明显的季节变化。本文对海藻生长的时空变化与某些环境因子间的关系作了分析探讨。

The preliminary Study on the Ecology of Marine Algae on Zhongjeshan Islands

A preliminary study on the ecology of marine algae in the intertidal zone of the Zhongjeshan Islands, Zhejiang Province was carried out from July 1986 to October 1988, The results embrace the follows: 1. The total number of the marine algae amounts to 56 genera, 94 species. The subtropical and warm temperate species predominate. The nature of the flora of the marine algae is related to the influence of the Taiwan Warm Current. 2. The vertical distribution of the marine algae on the rock was reported. The vertical distribution of marine algae is related to the tide. Waves can make the level of distribution of the biological species stretch upward. 3. The seasonal differences in species composition and biomass and the vertical levels of certain algae of the marine algae have been observed. The principal factors affected on the seasonal changes of the algae are the sea water temperature and climate factors.
