渤海湾南部滩涂贝类群落结构特征及其环境因子相关性研究
Characteristics of the shellfish community structure and its correlation with environmental factors in the southern tidal flats of Bohai Bay
摘要
Abstract
This study aimed to investigate the community structure characteristics of shellfish and their correlation with the environmental factors in southern Bohai Bay(Binzhou)by setting up 36 sampling stations in six sections covering the tidal flats(high tidal flats,middle tidal flats,and low tidal flats)and the subtidal zone.The results showed that a total of 30 shellfish species were collected in the tidal flats and the subtidal zone.23 species were observed in the tidal flats,with the dominant species of Potamocorbula laevis(Hinds 1843),Mactra quadrangularis(Reeve 1854),and Meretrix petechialis(Lamarck 1799)and 26 species were observed in the subtidal zone with the dominant species of Mactra chinensisi(Philippi 1864),Gomphina aequilatera,Terebra koreana(Yoo 1976),Nas-sarius succinctus(A.Adams 1852),and Nassarius variciferus(A.Adams 1851)The diversity index(H')and even-ness index(J')in the tidal flats were significantly higher than those in the subtidal zone,whereas the richness index(D)showed the opposite trend.The biomass(710.16 g/m2)and density(4523/m2)of the shellfish in the tidal flats were significantly higher than those in the subtidal zone(17.10 g/m2;35/m2).Additionally,multivariate analysis of the community structure revealed that shellfish were divided into five groups,including the eastern subtidal zone,the western subtidal zone,the western tidal flats,the eastern tidal flats,and the area including only the D4 station.Moreover,redundancy analysis was conducted to study the correlation between the dominant shellfish species and the environmental factors of the tidal flats and subtidal zones.The results showed that particle size and sand or silt content of the sediment were major factors affecting the shellfish distribution in the tidal flats,whereas phyto-plankton density,particle size,and sand,silt,or clay content of the sediment were major factors affecting the shell-fish distribution in the subtidal zone.Shellfish resources are abundant in southern Bohai Bay(Binzhou),but the protection or restoration of shellfish resources should be strengthened based on the ecological characteristics of the different tidal areas.This study provides a basis for the conservation and sustainable utilization of shellfish re-sources in the Bohai Bay region.关键词
