青岛市灵山湾海水浴场沉积物分布特征与影响因素

摘要

This paper analyzed the grain sizes of sediments at the Lingshanwan bating beach, Qingdao, discussed the characteristics of sediment distribution and identified the sediment transport trends. The results showed that the sediment type belonged to sand sorting from good to well. The hydrodynamic conditions in the study area were relatively stable. The study area was mainly influenced by wave, tide and coastal currents. The sediments in the northeastern study area were coarser than those in the southwestern area with relative poorer sorting. Trend analysis showed that the sediments transported southwestward along the coastline. The northeastern study area was eroded while the southeastern was deposited. With the large-scale development of economic zone along Qingdao west coast, erosion of the Lingshanwan bathing beach may be more serious in the future. Furthermore research should be launched continuously. This would provide fundamental data and reference to beach sand research and protection in this and other areas.%针对灵山湾海水浴场海滩沉积物进行了粒度测试，探讨了沉积物分布特征并分析了其输运趋势。测试结果表明，沉积物类型均为砂，分选好至较好，其沉积作用受相对稳定的水动力条件控制，主要受到波浪、潮汐和沿岸流的影响。灵山湾海水浴场东北侧偏粗，分选略差，西南侧偏细，分选较好。粒度趋势分析显示，研究区沉积物有北东-南西向的沿岸搬运趋势，东北部为侵蚀区，西南部为沉积区。随着青岛西海岸经济新区的大规模开发，灵山湾海水浴场侵蚀可能将会更加严重。日后持续的调查研究，将为本区和其他地区的海滩砂研究和保护提供基础资料和参考。
