| 摘要: |
| 本文研究了大亚湾埔渔洲红树林区软体动物种类组成,数量分布和群落结构特点,报道软体动物已鉴定有35种,主要由樱蛤科、帘蛤科和汇螺科组成;按种类性质,大多属于广温广盐广布种。平均生物量为51.15g/㎡,平均栖息密度为58个/㎡,群落可划分高、中、低3个分布带,同时简要地分析了生物群落与环境因子的关系。 |

| Abstract: |
| The species composition, distribution of biomass and habitat density, and community structure of Mollusca are analysed for appraising the nuclear power station's effect on Mollusca in the mangrove of Puyuzhou, Daya Bay. The 35 mangrove area Mollusca species collected in this study were mostly euryhalinous-eurythermic and eurytopic species. Cerithidea cingulata, C. microptera, Batillaria zonalis, Geloina coaxans and Moerella culter were dominant in numbers. The average biomass and density of Mollusca were 51.15g/㎡ and 58 ind/㎡. The vertical distribution of density in different zones was in the order：middle tide zone>low tide zone >high tide zone; while that of biomass was in the order: middle tide zone>high tide zone>low tide zone. The community structure were characterised by three distribution zones: Glaucomya chinensis-laternula anatina-Cerithidea microptera at high tide zone; C cingulata-C.microptera-Geloina coaxans at middle tide zone and Moerella culter-clausinella isabellina-Angulus sp. at low tide zone. It is shown that Mollusca community structure in the mangrove area is stability. Finally the relation of Mollusca to enviromental factors are discussed briefly. |
