| 根据1986年12月 - 1989年9月生态零点调查资料，使用PDP－11/34A型电子计算机，应用Bray-Curtis相似性指数等划分和分析大亚湾潮间带生物群落及其结构特点，以评价大亚湾核电站投产后对海洋环境的影响。结果表明，按底质类型大亚湾潮间带生物可划分为岩石相、沙滩和红树林泥滩群落，且各生态相隐蔽、半隐蔽和敞开断面群落与环境因素密切相关。 |

| Abstract: |
| This paper is based on data obtained in a Dec. 1986 to Sept. 1989 marine ecological survey of Daya Bay intertidal benthos. A PDP-11/34A computer was used, and Bray-Curtis’ similarity index, Shannon-Weaver’s species diversity index (H'), Margalef’s species richness (d), Pielous’s species evenness (J) and Mcnaushton’s species dominance index(D) were applied to analyze the communities and the features of the structure of intertidal benthos near the Daya Bay nuclear power station and appraise its effects on the marine environment. The results showed that the intertidal benthos in Daya Bay could be divided into rocky, sandy beach and mud-mangrove communites according to the substrate forms, and could also be divided into sheltered, semisheltered and exposed communities based on the effects of the wind-waves, tide and tidal stream. The representative species of communities were different in the high, middle and low tide zones. Marine environment factors affected the intertidal benthos in Daya Bay, but the main causes for differences among communities were the substrate form and hydrodynamic factors of the wind waves, tide and tidal stream. |
