摘　　要：通过对琼州海峡表层沉积物中54项指标统计、元素组合特征分析、沉积物环境质量评价、锆英石资源潜力评价和元素比值研究,结果表明,SiO_2、Al_2O_3和TFe_2O_3是研究区表层沉积物中的最主要组分,元素的含量与粒度存在明显的相关性;元素组合以亲粘土组合为主;海峡沉积物环境质量良好,锆英石资源潜力巨大;海峡东部和中部海域海流动力较强,属氧化沉积环境。By analyzing 54 statistical indicators of surface sediments from the Qiongzhou Strait, element association characteristics, and assessing the sediment quality and the resource potential of zircon and studying the element ratios, the results showed that SiO2, A1203 and TFe203 were the most important components in surface sediments of the Qiongzhou Strait, and there was obvious correlation between element content and particle size. Element combination was basically pro-clay mix. Environmental quality of surface sediments was good, and Zircon resources had a great of potential. Ocean current power was strong in the eastern and central area of the Qiongzhou Strait, and the sedimentary environment belonged to oxidation one.
