泸沽湖现生介形类的研究

Study on the Extant Ostracods in Lugu Lake

介形类在古气候环境研究、水环境监测及地质勘探等方面具有重要作用,因此加强对现生介形的研究具有重要意义。本文通过采集泸沽湖的表层沉积物,在泸沽湖沉积物中鉴定出介形类7属7种,分别是泽氏玻星介Candonocypris novaezelandiae,克氏丽星介Cypria kraepelini,意外湖花介Limnocythere inopinata,弯叶豆形玻璃介Fabaeformiscandona myllaina,豆形豆形玻璃介Fabaeformiscandona fabaeformis,楔形真星介(比较种) Eucypris cf.cuneata,青春金星介Cypris pubera,河星介属Potamocypris,经过介形类属种的鉴定和统计分析,获取介形类的定量生态信息,为泸沽湖水环境监测和古气候环境研究奠定基础,同时丰富我国现生介形类生境数据。

Ostracoids play an important role in paleoclimate environment research, water environment monitoring and geological exploration, so it is of great significance to strengthen the research on extant ostracods. In this paper, 7 genera and 7 species of ostracods were identified in the sediments of Lugu Lake by collecting the surface sediments of Lugu Lake, namely Candonocypris novaezelandiae, Cypria kraepelini, Limnocythere inopinata, Fabaeformiscandona myllaina, Fabaeformiscandona fabaeformis, Eucypris (comparative species) Eucypris cf.cuneata, Cypris pubera, Potamocypris, ossicles species to obtain quantitative ecological information of ostracods, lay the foundation for water environment monitoring and paleoclimate environment research of Lugu Lake, and enrich the habitat data of ostracods in my country.
