Species Composition and Spatial-Temporal Distribution of Ben-thic Shellfish in Subtidal Zone of Beihai in Guangxi
摘要
Abstract
In order to understand the distribution characteristics of benthic shellfish in the subtidal zone of Beihai,and provide reference data for the protection,development and utilization of benthic shellfish,the spe-cies,quantity and spatiotemporal distribution of benthic shellfish in subtidal zone of 4 sea areas(Lianzhou Bay,Qiaogang,Bailong and Yingpan)in Beihai City were investigated by diver scuba diving and quantitative collection of seabed samples.The results showed that there were 2 classes,9 orders,31 families,60 genera and 102 species of subtidal benthic shellfish in 4 sea areas of Beihai,including 17 species of 13 families,14 genera belonged to Gastropoda and 85 species of 46 genera of 18 families belonged to bivalves.There are 55 species in spring,76 species in autumn,and 29 species shared by spring and autumn.The number of species and indi-viduals in the Lianzhou Bay sea area in autumn is the least,the number of species in the Qiaogang sea area in autumn is the most.The largest number of individuals appeared in Yingpan sea area in spring.The highest average habitat density was in the spring of the Yingpan sea area,reaching 27.35 ind./m2,and the lowest av-erage habitat density was in the spring of the Lianzhou Bay sea area,only 1.00 ind./m2.The dominant spe-cies in the four sea areas were significantly different in spring and autumn.The results of multiple biodiversi-ty indices showed that the biodiversity of benthic shellfish in the Yingpan sea area in spring was poor,and the community structure of benthic shellfish was seriously disturbed.The biodiversity of benthic shellfish in the four sea areas in autumn is abundant,and the community structure of benthic shellfish in autumn was gener-ally in a relatively healthy state.关键词
