海砂是重要的海底矿产资源。海南岛海砂资源广泛地分布于海岸带和陆架区域，规模较大，品质优良，富含重矿物。文中阐述了海南岛周边海砂资源的基本分布特点，结合多个海砂资源勘查专项工作，以重矿物砂矿和集料用海砂为讨论重点，回顾了海南岛周边海砂勘查的工作进展和主要成果。通过勘查，海南岛周边海域共圈定了15处重矿物砂矿异常区，并探明了1处大型锆钛砂矿床，但由于调查研究程度不高，海域重矿物砂矿资源潜力并不明朗。海南岛周边底质调查比例尺基本达到了1∶25万，为海洋集料用海砂的勘查提供了扎实的基础。近年来在琼州海峡东口和琼西潮流沙脊区的勘查，探获了数十亿立方米的集料用海砂，预测资源潜力可达数百亿立方米。经综合分析，海南岛周边海域可圈定8处海砂资源勘查远景区，除了琼州海峡东口和琼西潮流沙脊区，琼东北侧陆架、琼西南侧陆架和北部湾一带，均是海砂资源的有利成矿区，并可能具有重矿物资源潜力。根据其具体沉积环境，分别探讨了各远景区的勘查目标和任务，结合现阶段工作进展和存在的问题，提出了今后海砂勘查的工作建议。

Marine sands are important submarine mineral resources. The marine sand resources of Hainan Island are widely distributed in coastal zones and continental shelf areas, with large scale, good quality and rich in heavy minerals. The basic distribution characteristics of marine sand resources around Hainan Island are described, and the progress and main achievements of marine sand exploration around Hainan Island are reviewed with emphasis on heavy mineral sand and aggregate sand. Through the exploration, 15 abnormal areas of heavy mineral placer have been delineated in the sea area around Hainan Island, and one large zirconiumtitanium placer deposit has been proved. However, due to the low level of investigation and research, the resource potential of heavy mineral placer is not clear. The scale of sediment survey around Hainan Island has basically reached 1∶250 000, which provides a solid foundation for the exploration of aggregate sand resources. In recent years, billions of cubic meters of aggregate sand resources have been discovered in the east entrance of Qiongzhou Strait and tidal sand ridge area of the western Hainan, and the resource potential is predicted to reach tens of billions of cubic meters. According to the comprehensive analysis, 8 potential exploration areas of marine sand resources can be delineated around Hainan Island. Except the east mouth of Qiongzhou Strait and the tidal sand ridge area of the western Hainan, the northeast continental shelf of Hainan, the southwest continental shelf of Hainan and Beibu Gulf area are all favorable enrichment areas of marine sand resources, and may contain heavy mineral resources potential. According to the specific sedimentary environment, the exploration objectives and tasks of each prospective area are discussed respectively. Combined with the current work progress and existing problems, the suggestions for the future marine sand exploration are put forward.
