福建三沙湾海洋生态环境研究

2000~2004年对三沙湾海洋生态环境进行了调查,分析了三沙湾海区多年来水质、水域养殖力(营养盐、叶绿素a和初级生产力)和浮游植物多样性的变化。调查后发现,养殖水域富营养化已经成为制约水产养殖业可持续发展的瓶颈,如何有效控制水体富营养化过程,降低海水养殖对环境产生的负面影响是一个非常现实的问题。因此,合理设置养殖容量、养殖方式、养殖种类,使退化的养殖海域得以修复,将对三沙湾海水养殖业的发展产生深远影响。

Study on Maine Ecological Environment of Sansha Bay in Fujian

Variation of water quality,culture force and phytoplankton diversity in the sea area of Sansha Bay for years were analyzed according to comparison of investigation data in 2000 with historical data.Its ecological harm was evaluated with the index method of poetical ecological harm.The contents of Cu in some water area of Sanduao were beyond the second standard of water quality while the ecological harm of heavy metals in sediment was slightly,except the serious pollution of Hg and Cd.Investigation on surface sediments of Sansha Bay was conducted too.
