摘要

摘要: 海南岛三亚湾海滩沉积物主要以中细砂为主,中值粒径在2.0~2.5 Φ之间,为细砂质,少量样品在1.0~2.0 Φ之间,属中砂质,适合于海滩旅游。近岸海底沉积物总体分布较细,为砂-粉砂-黏土的组合,仅仅在海湾西侧靠近岬角处,以中粗砂为主。近岸海底沉积物是低海平面时古河道的堆积物,能够为现代海滩提供很好的砂源,为确保海滩的稳定性提供了物质前提条件。但是,由于近20年的海岸开发,海滩东部受到人类开发活动的深刻影响,人为排放的有机物污染使海滩部分出现泥化和变黑,而且,由于人为的违规建筑物紧逼高潮线和大潮高潮线,破坏海滩的整体形态,改变海岸的动力条件,进而破坏了海滩旅游资源。

Abstract: Sediments of the Sanya Bay beach are mainly fine sand, and their mean grain-size diameters are mainly between 2~3 Ф and in good sorting,and thus the beach is a resource of tourism. Moreover,grain-sizes of the seafloor sediment show a combination of sand-silt-clay,and only near the cape in the west of the Sanya Bay,medium-coarse sands dominate and they were deposited in the last glacial. These ancient fluvial sediments can provide good sands for modern beach.
However,with the economic development,human activities have heavy influence on the coastal environment. Since the last two decades pollutant water to the Sanya Bay is becoming more and more from urban life with the city enlarging, so the east part of the Sanya Bay beach becomes black. Moreover, in the east of the beach,sand becomes coarser,indicating that backwash strengthens and takes fine sands away,because human constructions shorten extent of the splash zone. Therefore,there are some countermeasures using law to exploit and manage the Sanya Bay to ensure the sustainable development.
