【摘要】 本文阐述了中美两国的双壳类和螺类的生物组成状况、地理分布,其中在中国大陆有淡水双壳类11属140余种,包括14个特有种,而在美国有淡水双壳类335种,螺类516种。造成淡水贝类濒危与衰退的原因主要是人口压力、环境污染、栖息地变化和外来物种的入侵。中美两国对淡水贝类的生物多样性都进行了研究与保护,并取得了一定的成果,但中国对淡水贝类的研究与保护工作还有待加强。文章最后就中国淡水贝类的生物多样性研究与保护的发展方向提出了见解。
【Abstract】 Current status for biodiversity of freshwater mollusks in China and America was reviewed and the factors of mollusk decline were also described in the paper.There are more than140 species mussel belonging to 11 genera and 14 species only exist in China.335 species freshwater mussel and 516 species freshwater snail distribute in America.The factors of mollusk decline are mainly overpopulation,environment pollution,habitat change and invasive of foreign species.The conservation and research of mussels,fingernail clams and snails were discussed for China and America respectively,but there still have more things to be done for biodiversity of freshwater mollusks in China.Freshwater mollusks conservation and research direction in China finally was proposed in the paper.
