crescent beach

At Changli Gold Coast,42 samples of particle size were col- lected on a coastal barchan,which was a typical coastal barchan chosen from all the barchans in this re- search region.

结果表明,昌黎黄金海岸新月形沙丘两翼、迎风坡脚、迎风坡、沙丘顶部、背风坡、背风坡脚的粒度总体上是中砂、分选好、偏度近对称和中等峰态,只有平均粒径在新月形沙丘表面的不同部位存在一定的差异,自迎风坡脚到沙丘顶部粒径变粗,背风坡粒径相对变细,到背风坡脚粒径又变粗,整个沙丘表面粒径顶部最粗、背风坡最细,其分布可以归入沙丘顶部砂物质最粗的分布模式。
