海岸带开发活动对锦州湾环境影响分析

The environmental impact analysis of coastal exploitations in Jinzhou Bay

为正确评价海岸带开发活动对锦州湾海域产生的影响,从围填海活动和临海工业对海岸带开发活动产生的环境效应影响做了分析,并根据搜集的2004～2008年的水质监测数据对锦州湾海域进行了海洋环境质量评价。研究表明,2000～2009年,锦州湾海域面积减少了约2234ha,自然岸线减少了约2.2km;临海工业的发展及沿岸工厂排放的污染物使锦州湾海域的水质质量下降,主要的污染物为COD和油类,超标的重金属污染物主要为镉、铅、砷。

For appropriate guidance of coastal exploitations in Jinzhou Bay,we analyzed the environmental impact of coastal exploitations of the reclamation project and coastal industry.Marine environmental data of Jinzhou Bay collected between 2004 and 2008 were used to evaluate seawater quality.The results indicate that from 2000 to 2009,due to the reclamation activities,the area of Jinzhou Bay decreased nearly 2 200 hectares,and natural coastline decreased about 2.2km.Pollutants discharged from industries around the coast resulted in marine environment deterioration.The main pollutants in Jinzhou Bay were COD and oil;and the inorganic pollutants were cadmium,lead,and arsenic.
