| 摘 要： | 采用历史海图分析对比、~(210)Pb测年数据校核等方法,综合推算出珠江口不同地段的现代沉积速率。依据沉积速率大小和分布的特点,将珠江口划分出高速率沉积、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。再结合地形、动力和沉积特征方面的关系,又将该海区归纳为4大类沉积环境和8个亚环境。最后论述了高盐陆架水的上升作用对珠江口海区沉积环境的入侵和影响。

| Abstract: | Modern sedimentary velocity in different sections of the Pearl River Mouth in calculated mainly by analyzing and comparing historical sea charts, chec-king data of ~(210)Pb from survey years. Accrding to Characteristics of velocity variations and distribution, the Pearl River mouth is divided into four sedimentary
sub-sections. Then by considering topography dynamics and sedimentary characte-ristics, this section in again divided into four large sedimentary environment sec-tions and eight sedimentary sub-environments sections. Lastly, shelf water's invasion and influence on sedimentary environment of this mouth is dicussed. |
