摘要
澳门附近水域地处珠江三角洲前缘淤积带上,现代沉积作用旺盛,广泛分布着粘土质粉砂和粉砂质粘土。从沉积物四个粒度参数的分布特征,它们显示了陆域河流供沙的重大影响。文章还对本水域的现代沉积环境和沉积作用进行了分析,并对现代沉积与当地港口航道及海岸工程建设的关系进行了探讨,提出了一些建设性意见。
The watershed nearby Macao is located in the front marginal silting zone of Pearl River delta.Its modern sedimentation is rigorous and there are extensively distributions of clayey silt or silty clay. From the distributional characteristics of 4 grainsize parameters of the sediment, the immense influence of fluvial sands in relation to the land regions are revealed.This paper also analyses the modern sedimentary environment and sedimentation in this watershed. And with the relationship being discussed between the modern sedimentation and local harbour, navigational watercourse and coastal engineering establishment, some constructive suggestions are pointed out.
