摘要: 基于2015—2016海南新村港和2017—2018年黎安港两地海草床四季大型底栖生物生态调查数据, 对其群落结构进行比较。结果表明: (1)共记录两个区域海草床大型底栖生物96种, 其中新村港和黎安港各50种和62种, 环节动物是两地海草床的主要类群; 厚鳃蚕(Dasybranchus caducus)是其共有的优势种; 除秋季外, 新村港的大型底栖生物平均栖息密度均高于黎安港; 除夏季外, 黎安港的生物量皆高于新村港; (2)黎安港的Shannon-Wiener多样性指数(H′)、Pielou均匀度指数(J′)和Margalef丰富度指数(d)均高于新村港; 黎安港的丰度/生物量曲线W值远大于新村港, 后者海草床大型底栖生物群落结构比前者受到干扰更小; (3)基于群落栖息密度和生物量聚类结果都显示, 约15%的相似性水平上可将两地群落分为两组, 两地海草床大型底栖生物群落结构差别较大。结合上述研究和历史研究结果, 两地群落差异可能是由两地的水文特征差异和渔业养殖带来的污染差异引起的。与历史数据对比显示, 两地海草床保护区的大型底栖生物群落已有所恢复, 持续的保护和修复工作是有效且必要的。

Abstract:

Based on the ecological survey data of macrobenthos in the seagrass beds of Xincungang (20152016) and Li’angang (20172018) across four seasons, we compared their community structures. The results showed that: (1) A total of 96 species of macrobenthos were recorded in the seagrass beds of the two areas, with 50 species in Xincungang and 62 species in Li’angang. Both seagrass beds were dominated by annelids, and Dasybranchus caducus was a common dominant species. Except in autumn, the average density of inhabited macrobenthos in Xincungang was higher than in Li’angang, while, except in summer, the biomass in Li’angang was higher than in Xincungang. (2) The Shannon-Wiener diversity index (H′), Pielou’s evenness index (J′), and Margalef’s richness index (d) in Li’angang were all higher than those in Xincungang. The W value of the abundance/biomass curves (ABC) in Li’angang was also significantly higher than in Xincungang, indicating that the macrobenthos community structure in Li’angang’s seagrass beds was more stable and less disturbed. (3) Cluster analysis of community inhabited density and biomass revealed that the communities in the two areas could be divided into two distinct groups at a similarity level of approximately 15%, demonstrating significant differences in the macrobenthos community structure between Xincungang and Li’angang. Combined with historical research, these differences are likely attributed to variations in hydrological conditions and pollution from aquaculture activities. Compared with historical data, the macrobenthos communities in the seagrass bed protected areas of both locations have shown signs of recovery, suggesting that ongoing protection and restoration efforts are effective and necessary.
