| 摘 要： | 在已有研究数据和成果基础上,采用遥感影像资料,量算21世纪以来的珠江三角洲东四口门延伸情况,对比分析近期滩涂围垦进展变化、岸线延伸速度、悬沙分布动态和水域面积变化情况等。结果显示,21世纪以来东四口门片区的围垦增长速率和岸线延伸速度较上世纪稍有放缓,期间滩涂围垦速度和岸线延伸速度较快的区域是伶仃洋东部滨岸。

| Abstract: | The average drainage method,maximum 24-hour rainfall pattern flood discharge duration allocation method,runoff yield and concentration method are used to calculate the design discharge of a urban drainage pump station. Then the results are contrasted and analyzed of these three different methods,and the design discharge is selected which is suitable for the drainage pump station,providing a reference for design discharge determination of similar projects. |
