对嵊泗列岛岩相潮间带底栖生物种类分布进行的研究表明，种类的水平分布主要受盐度及海岸开敞度的影响，从近岸到外海，随着盐度及海岸开敞度的增加，潮间带底栖生物的种类数呈增加的趋势。不同海区的优势种不同，近岸较屏蔽区以软体动物及甲壳动物占优势，外海开敞区以甲壳动物及藻类占优势，近外海较开敞区为一过渡区；种类的垂直分布主要受潮区及海岸开敞度的影响，各海区不同潮区生物种类数均为中潮区多于低潮区多于高潮区，高潮区基本上为滨螺分布带，中潮区为日本笠藤壶－藻类带，低潮区为藻类带；外海区种类的季节变化明显，近岸区种类季节变化小。所有物种中，以底栖海藻的季节变化最为明显。
The study on species distribution of benthic organisms in the intertidal facies of the Shengsi Islands shows that the horizontal distribution of species is mainly affected by salinity and the degree of openness of the coast. From the coastal to the open sea, with the salinity and the openness of the coast Increasing, the number of benthic organisms in intertidal zone tends to increase. The dominant species in different sea areas are different from the shielded areas in the nearshore, which are dominated by molluscs and crustaceans. The crustaceans and algae are dominant in the open sea areas and the transition zone is from the open sea to the open area. The vertical distribution of the species is mainly affected by the tide The number of species in different tidal zones in each sea area was more than that in low tide area and high tide area, high tide area was basically Bin Ha distribution zone, middle tidal area was Japanese barnacle-algae zone , The low tide area is the algae zone, the seasonal variation of the outer sea area species is obvious, and the seasonal variation of the near-shore area species is small. Among all the species, the seasonal changes of benthic seaweed are the most obvious.
