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。
Base on the existing research data and results, the estuary, extension of the four eastern outlets of Pearl River Delta since the 21 st century was measured by remote sensing image data, in order to analyze and compare the changing trend of the tidal fiat reclamation, coastline extension, water area and suspended sediment distribution. The results showed that the increasing rate of reclamation and the rate of： the coastline extension since the 21st century were lower slightly than last century. And during the research period, reclamation rate and coastline extension rate of the coast zone in the eastern area of Lingding estuary were higher.
