集约用海对海洋环境的影响—以辽宁省渤海区域为例

Abstract

本文通过分析辽宁省渤海海域几个“正在建设”的区域近十年的集约用海，阐述了集约用海对该区域海洋环境的影响。结果表明：随着集约用海的开发，研究区域海洋经济产值呈现快速增长趋势，而自然岸线和湿地总面积呈逐年减少趋势；海湾纳潮量和水交换能力也有所减小；水质和沉积物污染物指数呈上升趋势，污染因子增多。研究说明了集约用海的开发促进了该区域海洋经济增长，但同时对海洋环境造成了负面影响。 The impact of intensive use of sea way development activities on marine economy and coastal ecologic environment was researched, by analyzing the intensive use of sea way development process in the last ten years surrounding the Bohai Sea of Liaoning Province. With the intensive use of sea way development, the results show that marine economy of Liaoning keeps up rapid development. The natural coastline and wetland area decrease trend year by year. Tidal volume and water exchange capacity of the bay were decreased gradually. Index of water quality and sediment pollutant is on the rise, pollution factor increased. The results show that development of intensive use of the sea in Liaoning province played an important role in promoting economic growth, but also brought negative influence to the Marine ecological environment.
