摘要:
针对福建长乐东部海岸风沙活动地区,观测海滩、半固定沙丘、植被固定沙丘不同地貌单元的风沙流输沙量,捕集不同高度输沙样品,据此分析研究区不同地貌的风沙流的结构特征值λ.结果表明:在海滩后缘,风沙流的中细粒沙质量分数从底层向上呈减小趋势,而粉沙沙粒的质量分数从底层向上呈增大的趋势.在活化沙丘顶部,风沙流中的中细粒沙质量分数随高度的变化无明显规律,而粉沙沙粒的质量分数从底层向上呈缓慢增大趋势.在固定沙丘顶部,中沙质量分数随高度的变化平缓,而细沙质量分数从底层向上呈缓慢减小趋势.这种风沙流结构特征,适合采用竹栅栏、马鞍腾、单叶蔓荆、滨刺麦和木麻黄树等多级防沙组合体系.
Abstract:
Investigation and observation were carried on in the sandstorm field in Changle east seacoast in Fujian Province including samples collection,laboratory anglicizing and comprehensive studies.The result indicated the percentage of middle and fine sand in wind-blown sand was decreasing from the bottom up,while the percentage of silt was increased from bottom up in the posterior edge of the beach.In the top of activation sand dunes,the percentage of middle and fine sand in wind-blown sand shows no significant variation with height,and the percentage of silt was slowly increasing from the bottom up.In the top of the fixed sand dunes,the percentage of the middle sand change flat with height,percentage of silt was slowly reducing from the bottom up.The multi-level defense system should be applied to prevent and control seacoast sandstorm such as using bamboo barriers,saddle-teng,Vilex trifolia Var.,Simplify olia,Spinifex littoreus(Burm.f.) Merr and Casuarinae quisetifolia Wood.
