Study on the effect of Mytilopsis sallei on ecological environment in Yundang Lagoon, Xiamen

Abstract

外来物种沙筛贝(Mytilopsissallei)原产于中美洲热带水域,随着航运的发展入侵世界上许多国家和地区,对入侵地造成巨大的经济损失。筼筜湖位于厦门岛西南部,旧称筼筜港,原是一片天然的港湾。20世纪70年代初,为围海造田,修建了西堤,使筼筜港变成一座基本封闭的人工泻湖,水体污染较为严重,水交换能力大大减弱,改称筼筜湖。筼筜湖水体呈富营养化状态,湖内属重污染水体。海洋入侵种是生态变化的主要驱动者,它们适应当地栖息环境,与本地种竞争,还可能是带菌者,对生物多样性造成严重的危害。因此,只有研究沙筛贝与其他生物和非生物因子的相关关系,才能正确地判断沙筛贝的利弊及其对生态环境的影响程度。 本研究...The normal distribution of alien species Mytilopsis sallei is in tropic water area in Central America. It has been introduced into many countries and areas by attached to hulls of ship. Mytilopsis sallei made a great economic lose in the invasive areas. Yundang Lagoon, which lies in the western part of Xiamen Island, used to be a natural bay called Yundang Harbor. In the early 1970s, a great numbe...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2262006115234
