【摘要】 本文以杭州湾北岸软相潮间带A—E5条断面(图1)的连续6年(1975—1980年)底栖动物生态调查资料为依据,分析上海石油化工总厂于1977年投产后对该区环境质量的影响。结果表明,底栖动物群落的变化相当明显。这是水质、底质和地形环境改变综合作用的结果。其中,断面A主要是因附近筑堤填海、泥沙淤积所造成;其他4条断面主要乃与不同程度的有机污染密切相关。更多还原

【Abstract】 Effect of the operation of the Shanghai Petroleum Industry Combine, which was started in 1977, on the adjacent soft-bottom intertidal zone has been analyzed, basing on data obtained from six years of ecological surveys(1975-1980) over five transects, A-E(fig.1).Changes in community structure of be-nthic fauna were very obvious. These changes were brought about by the complex effect of water and bottom soil quality and topographic changes. Transect A was related largely to the construction of a dam nearby and siltation, while the other four transects were, on the whole, related to organic pollution in different degrees.更多还原
