厦门海岸工程对岸线变迁及海洋环境的影响研究

摘要

This research adopts the three remote sensing images of Xiamen in 1989,1997 and 2007 to study the coastal line changes with the support of Arcview 3.3. Based on the data collected, the situation of the reclamation area in Xiamen is summarized. The results show that the reclamation was concentrated in West Xiamen sea area and Tongan Bay before 1980. The reclamation area is 5 605 hm2 in Western Xiamen sea area and 2 796 hm2 in Tongan Bay. The whole reclamation area in Xiamen sea area reached 982. 05 hm2 from 1980 to1999, and the 762. 44 hm2 from 2000 to 2006. Over a long time, the coastal engineering constructions not only promoted the marine economic and social development in Xiamen, but also brought severe impacts on the marine environment, such as, changes in coastline topography, significant reduction in tidal volume, destruction of biological diversity, deterioration of water quality and so on.%在Areview3．3软件的支持下，以厦门市1989年、1997年和2007年三个时期的遥感影像图为数据源，研究厦门的海岸变迁；通过搜集整理文献资料，总结围填海面积增长情况，研究表明：1980年以前，厦门的围填海以西海域和同安湾居多，西海域围填海面积达5605hm^2，同安湾围填海面积2796hm^2；1980年-1999年，整个厦门海域的围填海面积为982．05hm^2；2000年-2006年，整个厦门海域的围填海面积为762．44hm^2。长期多项海岸工程建设提升了厦门海洋经济社会的发展水平，但也使得海洋生态环境受到了严重的影响，如海岸地形地貌改变、纳潮量大量减少、生物多样性被破坏、水质恶化等。
