计算东海29 个试验点污损生物群落之间的相似系数,并进行聚类分析。根据分析结果,东海污损生物群落可分为4 个类型: 河口群落、近岸群落、内湾群落和远岸群落 The similarity coefficients of fouling communities in 29 experimental sites in the East China Sea were calculated and clustered. According to the analysis results, there are four types of fouling biological communities in the East China Sea: estuarine communities, coastal communities, inner-bay communities and far-shore communities
