海岸带开发活动对大连湾环境影响分析

Environmental impact analysis of coastal exploitation in Dalian Bay

为正确评价海岸带开发活动对大连湾海域产生的影响，本文从围填海活动和临海工业两个方面对海岸带开发活动产生的环境效应影响做了趋势性分析，并根据搜集的2005～2008年的水质监测数据对大连湾海域进行了海洋环境质量评价。研究表明，2000～2009年，大连湾海域面积减少了约900hm^2，自然岸线减少了约4km；临海工业的污染物排放导致海水环境恶化；根据水质数据监测结果，大连湾海域超标的污染物主要为无机氮、磷酸盐和油类。

In order to the correct guidance of coastal exploitations in Dalian Bay, the trend analysis of the environmental impact of coastal exploitations was done based on the reclamation project and coastal industry. The data collected from the marine environmental monitoring in Dalian Bay 2005 - 2008 were used to evaluate the seawater quality. The results showed that the study area in Dalian Bay was decreased nearly 900 hectares and natural coastline decreased about 4 km due to the reclamation activities from 2000 to 2009. The pollutants discharged from industries around the coast lead to the marine environment deterioration. According to the monitoring results of water quality, the main pollutants in Dalian Bay were inorganic nitrogen, phosphorus and oil.
