摘要
本文通过山东半岛海岸地貌类型与沿岸波浪、潮汐发生学关系的对比分析,引入浪潮作用指数 K,K=2.5×(H/R),H 为平均波高,R 为平均潮差.K>1时,海岸地貌演变的动力以波浪作用为主,海岸极少发育潮汐叉道和落潮三角洲,但连岛坝发育较好;K<1时,海岸地貌演变的水动力以潮汐作用为主,落潮三角洲、潮汐叉道较发育;K 值接近于1时,发育潟湖等过渡海岸地貌类型.
Based on contrasting coastal morphology with wave heights and tidal ranges of the Shan- dong Peninsula,the paper has reached the conclusion that the coefficient K has significant roles in discriminating the types of coastal morphlology.K=2.5x(H/R),where H=mean wave height;R=mean tidal range.When K>1.0,physical processes are dominated by waves,and coasts tend to develop long,smooth,barrier coasts with few inlets and poorly developed ebb deltas,but with well-developed tombolos.When K<1.0,physical processes are dominated by tides and coasts tend to develop short,drumstick-shape barrier with well-developed ebb deltas and inlets.When the value of K tends to be 1.0,physical processes are dominated by waves and tides,and coasts tend to develop lagoons,barrier.
