以莱州湾东南岸1979~2014年的Landsat MSS/TM/OLI-TIRS影像为数据源,利用野外调查、遥感地貌解译和地理信息系统等方法,研究了近40年来莱州湾海岸地貌、海岸线和地貌淤蚀状态演变,分析了人类活动对地貌过程以及海岸线变迁的影响.结果表明：潍河河口、胶莱河河口、海庙港到刁龙嘴以及三山岛附近海岸岸线空间变化幅度较大,最大变化率为300．51 m/a,海岸淤涨明显,人工开发贡献较大；太平湾南端到海庙港以北海岸以及虎头崖西侧出现侵蚀.在人类活动影响下,自1979年以来,各地貌类型与盐田、养殖池之间的转化最为频繁、面积转化较大,海岸线向海推进明显,海岸开发到1988年进入一个围垦活跃期,之后围垦活动减弱,到2005年又进入一个小高峰,之后便进入平缓期.因此,最近40年来人类活动在莱州湾东南岸地貌演变过程中起着十分重要的作用,合理规划和规范开发活动是促进山东半岛蓝色经济区崛起的重要环节.

Taking the Landsat MSS/TM/OLI-TIRS remote sensing images since 1979 to 2014 as the main sources of information, field survey, remote sensing and GIS were used to study the change in coastal landforms,coastlines,geomorphic siltation and erosion patterns in southeastern of the Laizhou Bay for the last 40 years so as to trace the impact of human activities. The result shows that coastline at Weihe River,Jiaolai River,Haimiao Port,Diaolongzui,Sanshan Island changed largely,the maximum change rate was 300. 51 m/a, and the accretion was clear for the coast because of human activities;the erosion occurred at the south of Taip-ing Bay to the north of Haimiao Port and the west of Hutouya. As for effection of human,coastline advanced seaward gradually,the conversion was most frequently,and transformation of area was large,which showed dif-ferent landforms convert to salina and breeding pool since 1979 . The exploitation of coast became active in 1988 and 2005 then reached a plateau. Therefore,human activities played a very important role in the geomor-phologic process evolution of Laizhou Bay in recent 40 years. Hence, reasonable planning and specification de-velopment are important ways to promote the rise of Shandong Peninsula blue economic zone.
