摘要
本文还简要分析了浙江贝类分布的特点和区系组成。指出浙江南北沿海因受近岸低盐水系和外侧高盐水系影响的强弱不同。贝类分布呈现出明显的南北差异;随纬度降低,贝类种类增加,热带性加强,整个区系表现出亚热带性质。
Over the years,we have accumulated a lot of shellfish specimens in the course of undertaking biological sample censusing along Zhejiang coast.After prelimiary examination of these samples,there are 142 species,belonging to 43 families of Prosobranchia,5 species are recorded for the first time in homeland,52 species of them were not been recorded formerly in Zhejiang Province. A brief discussion has also been made on the characteristices of geographical distribution and faunal composition of shellfishes along the Zhejiang coast.It is showed that the distribution appears varied owing to the difference of latitudes.With the lowing of latitude,the number of composition species,especially tropical species, incieas(?)s.So the whole fauna is of subtropical character.
