1990—1993年对蓬莱西庄海岸附近海域进行了水文、水深、地质地貌和泥沙等13项测量和调查。整理分析实测资料井结合数值计算，首次分析研究了登州浅滩的作用，并着重论述了浅滩被破坏后袭击岸边的波浪增大，波能增加到5—7倍，沿岸净输沙量增加到3—5倍。文中指出西庄海岸侵蚀加剧的主要原因是，登州浅滩被破坏后失去防浪消波作用而造成的。
From 1990 to 1993, 13 measurements and surveys of hydrology, water depth, geomorphology and sediment were carried out on the sea near Penglai Xizhuang coast. Finishing analysis Data and well calculation, the function of Dengzhou shoal was analyzed and analyzed for the first time. Emphatically discusses the increase of waves which hit the shore after the shoal was destroyed, the wave energy increased to 5-7 times and the net sediment discharge along the coast increased To 3-5 times. The article points out that the main reason for the increased coastal erosion in Xizhuang is that the dam of Dengzhou lost its anti-wave and wave-breaking effect after being destroyed.
