| 摘 要： | 根据浅水波浪的底摩擦效应，对鲁南灵山湾和臼－岚山镇近岸区进行了波浪的海底摩擦力计算。波浪的海底摩擦力等值图与已知滨海锆石砂矿资料对比表明，底摩擦力大于０．１８Ｎ／ｍ＾２的动力分选区有利于重矿物砂富集。据此，进一步预测了鲁南近岸带的砂矿富集区。

| Abstract: | According to bottom friction effect of shallow water wave, the bottom friction force of the waves have been computed in Lingshan Bay and Shijiusuo Lanshantou nearshore areas. The isogram of the bottom friction force are compared with the data of littoral zircon placer, it shows that the heavy minerals were concentrated in the hydrodynamic sorting areas where bottom friction force are more than 0.18 N/m 2. Futher, prospecting areas of the littoral placer deposit have been predicted in the nearshore zone, Southern Shandong Province. |
