| 摘 要： | 文章分析了珠江河口海区泥沙来源及淤积动态,采用以历史海图分析对比为主,~(210)Pb测年数据校核等方法,参考有关沉积速率定性方面的标志,推算出珠江口不同地段的现代沉积速率,并相应划分出高速率沉积、快速率沉积、中速率沉积和慢速率沉积或稍有侵蚀等4个分区.进而,还论述了沉积作用的特征.

| Abstract: | The paper has analysed the source of silt and the depositional trend in the Pearl River Mouth. The analysis is made by mainly comparing historical sea charts and checking data of 210Pb from survey years. In reference to some natural signs concerned with sedimentary velocity, the paper has calculated modern sedimentary velocity in different sections of the Pearl River Mouth,and thus dividing these sections further into four corresponding sub-sections of modern sedimentary velocity. In addition, four characteristics of sedimentation are discussed. |
