本文报道了浙江省象山县爵溪镇下沙中全新世海滩岩中的部分热带贝类，计有８属９种。这一动物群的现生种均生活于热带海域的潮间带及潮下带。研究结果表明该区海滩岩是迄今发现的拥有大量热带生物的最北面的海滩岩，进一步证实了海滩岩是热带海洋的产物，以及浙江沿海地区中全新世时的气候与现代气候有很大差别，这对古气候变迁的研究具有重要意义。
In this paper, we report the distribution of some tropical shellfish in the Holocene beach rocks in Xisha, Jixi Town, Xiangshan County, Zhejiang Province. There are 9 genera and 8 genera. The current species of this fauna live in intertidal and subtidal zones in the tropics. The results show that the beach rocks in this area are the northernmost beach rocks with a large number of tropical organisms discovered to date, further confirming that the beach rocks are the products of the tropical oceans and that the mid-Holocene climate in Zhejiang coastal areas is quite different from the modern climate , Which is of great significance to the study of paleoclimate changes.
