| sand dune An accumulation of loose sand heaped up by the wind, commonly found along low-lying seashores above high-tide level, more rarely on the border of large lakes or river valleys, as well as in various desert regions, where there is abundant dry surface sand during some part of the year | 沙丘 (被风堆积的松散的沙的沉积，常在有很高的潮水和地势低洼的海边，很少在大湖边或河流边。同样也在很多沙漠地区，那里有很多多年积累在地表的沙。) |
| sand dune fixation Stabilization of dunes effected by the planting of marram grass (Ammophila arenaria), or rice grass, whose long roots bind the surface layers of sand and so hinder its removal by wind. A larger scale method of dealing with the same problem is by afforestation | 沙丘固定 (通过种植滨草(砂滨草蚤缀属)或稻草稳定沙丘，这些草长长的根可以绑住沙的表面因此可以阻止沙被风吹动。更大规模的处理同样问题的方法是造林。) |
