摘　　要：本文探讨长乐东部沿海及海坛岛两地海岸风沙地貌的成因,作者根据野外调查结果分析得出风况、沙源和地形空间是长乐东部沿海及海坛岛风沙地貌发育的基本条件,认为气候变干的趋势和人类活动因素是加速海岸风沙地貌形成的触发因素。This paper discusses the contributing factors of coastal eolian landform along the coastal area of Changle and Haitan Ialand. It expounds that the wind regime, sand supply and topographic space are the basic requirement to the formation of coastal eolian landform; and points out that the tendency of climate drying and humanity activities are the trigger factors to speed up the formation of coastal eolian landform.
