摘要
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。
The effect of the reclamation activities on the coastal ecologic environment in Liaoning province was studied.The photographs were from the remotely sensed Figure 5（1990,2000,2005,2008,2009） and the reclamation data,from 1990 to 2009.The reclamation area in Liaoning Province was increased 627 km^2,about 53.6%.The natural coastline reduced 246.8km,26.7%,mainly in Dalian and Huludao City.The total area of the Gulf reduced from 1 367 km^2 to 1116km^2,18.4%,mainly in the Jinzhou Bay,Pulandian Bay,Dalian Bay,Dayao and Xiaoyao Bays.The regions around the sea mouth of activity increased,but the ratio was not high,the reclamation lead to 104 islands lost independences,connected with the mainland.
