福建长乐东部海岸沙丘发育成因及特征

Origin and Characteristics of Coastal Dunes in Eastern Changle of Fujian Province

通过对长乐东部沿海海岸沙丘的形成及其发育成因进行分析,认为风况、沙源和地形空间是形成该地区海岸沙丘的基本条件。另外,根据沙丘的空间组合、形态特征、地貌特点等,对该地区的海岸沙丘分布形态进行了进一步的分类阐述。

Studying on the formation and development origin of coastal dunes along the coastal area in the eastern part of Changle County, it is considered that the wind conditions, sand source and landform are the essential points of shaping up the coastal dunes in the surveyed area. In the paper, the distribution of coastal dunes in the area is under a farther expatiation according to the spatial array, morphological characters and landform characteristics of sand dunes.
