| 摘 要： | 地处陆、海交界的潮间带,底栖生物与栖息环境密切相关,环境一旦受污染,生物群落结构将发生变化,影响到生态平衡。位于杭州湾北岸中部的上海石油化工总厂,投产后对该湾环境质量是否有潜在污染的可能性,将是个重大问题。为了比较本厂投产后对本区域生态学的影响,在上海市环境保护局领导下,上海石油化工总厂、上海市卫生防疫站、国家水产总局东海水产研究所和国家海洋局第三海洋研究所等单位相互协作,自1975年5月开始在该湾软相潮间带设五个断面,逐年定期地开展调查。

| Abstract: | Shanghai Petroleum-Chemical Industry Combine lies in the middle of the northern coast in Hangzhou Bay. In order to compare the ecological changes in the Bay before and after the operation of the Combine,a survey has been conducted since May,1975 for the benthic faunal community in the soft bottom intertidal zone along the northern coast in the Bay. In all, five sampling sections were chosen, namely sections A, B, C, D and E respectively. This paper, for the first time, reports the annual data of benthic fauna taken for the periods from May 1975 to July 1976. The results indicated that the number of species in this survey area were comparatively poor.For five sections,only 82 species of macrofauna have been identified,in which, 23 species were found to be dominant species. Species composition was dominanted by Crustaceans.Both the habitat density and biomass were also comparatively low, the mean were 442 Indiv./m2 and 22.1 gram./m2 respectively. Except for section A, number of species, density and biomass in all other sections turned out to decline progressively from high tide regions to low tide regions. The calculation of "percentage community affinity" for five sections indicated that sections B, C, D and E were very similar. The similarity of community at sections B, C, D and E were equally different from that of section A. The seasonal variation of organisms in this area could be attributed to the seasonal fluctuations of temperature and the seasonal transport of sediments due to seasonal winds. The community structure in this area was normal. The results from the analysis of the contents of adverse matters in water and substrate showed no sins of pollutions in this area. |
