摘要:

2006年3月和7月分别对珠江口疏浚物倾倒区附近的大型底栖生物进行了调查。对比分析了倾倒区内外大型底栖生物种类数、丰度、生物量、优势种和种类多样性指数的差异。 结果表明,海洋倾倒可能使倾倒区内大型底栖生物种类、丰度、生物量和种类多样性降低, 但对海区优势种的影响较小。AMBI和BENTIX指数评价结果认为倾倒区内底栖生物受到轻微干扰, 倾倒区附近海域大型底栖生物群落在3月受干扰程度较7月大。丰度生物量比较(Abundance/biomass comparison, 简称ABC)曲线分析结果认为倾倒区内大型底栖生物群落受到海洋倾倒活动轻微或中等程度的干扰。

Abstract:

Macrobenthos was investigated at the Pearl River Estuary ocean dumping site in March and July 2006. Differences in species quantity, abundance, biomass, the dominant species and species diversity index of mactobenthos were analyzed inside and outside the dumping site. The results showed that the ocean dumping may have decreased species quantity, abun-dance, biomass and species diversity of mactobenthos. AMBI and BENTIX indices revealed that macrobenthic communities indicated slight interference at the ocean dumping site. Macrobenthic communities showed greater interference in March than in July. ABC (Abundance/biomass comparison) revealed that macrobenthic communities had slight or moderate interference at the ocean dumping site.

Key words: Pearl River Estuary, macrobenthos, community, ocean dumping site
