围填海工程对淇澳岛附近水域环境因子与生物群落的影响

摘要

Land reclamation is an important way to use the ocean.But frequent human activities have a far-reaching influence on local marine ecosystem.Using the Qi'ao Island sea area as the study area,we surveyed the environmental factors and the changes of the biological community before and after reclamation.From the trend of the changes in the environment and the changes of phytoplankton,zooplankton,and the diversity and species of fish before and after reclamation,we investigated the influence on local marine ecosystems caused by the reclamation projects around the southern Qi'ao Island from 2010 to 2014.The results showed that the reclamation has had different degree of negative impact in terms of heavy metal pollution and eutrophication,and reduced the stability of local biological community.The community species has also decreased after the reclamation.%围填海工程是人类利用、开发海洋的重要方式,但是频繁开展的人类围填海活动对当地的海洋生态系统产生了深远的影响.以淇澳岛附近水域为研究区域,调查该水域围填海前后环境因子与生物群落的变化情况,从环境的变化趋势以及浮游植物、浮游动物和鱼类在围填海前后种类及多样性的变化入手,研究从2010-2014年淇澳岛水域南部半潮礁围填海工程对当地水域生态系统造成的影响.结果表明,围填海工程对水体的重金属污染及富营养化都有着不同程度的负面影响,并降低了当地水域生物群落的稳定性,群落种类较围填海之前有所减少.
