为说明辽宁省围填海开发活动对海岸带生态环境的影响,本文提取遥感图5期(1990年、2000年、2005年、2008年、2009年)的围填海信息,分析得出从1990年到2009年,辽宁省围填海面积增加了627 km2,增加了53.6%。围填海导致全省自然岸线减少246.8 km,减少了26.7%,自然岸线的缩减主要集中在大连市和葫芦岛市。海湾总面积由1 367 km2减少为1 116 km2,减少18.4%,主要在锦州湾、普兰店湾、大连湾、大小窑湾。河口区域围海活动有增加,但比例不高,围填海导致104个岛屿失去其独立性,与大陆相连。
In order to illustrate the impact of reclamation activities in Liaoning Province on the ecological environment of the coastal zone, this paper extracts the reclamation information from the remote sensing images of Phase 5 (1990, 2000, 2005, 2008 and 2009) By 2009, Liaoning reclamation area increased by 627 km2, an increase of 53.6%. The reclamation led to a decrease of 246.8 km in the natural shoreline of the province and a decrease of 26.7%. The natural coastline reduction mainly concentrated in Dalian and Huludao. The total area of the bay decreased from 1 367 km2 to 1 116 km2, a decrease of 18.4%, mainly in Jinzhou Bay, Pulandian Bay, Dalian Bay and Dayaoyao Bay. The estuarine sea area activities have increased, but the proportion is not high, reclamation led to 104 islands lose their independence, connected with the mainland.
