基于已有研究资料和成果,对伶仃洋水域面积和岸线的历史演变进行了分析和总结,并利用遥感资料准确计算了过去近30 a内伶仃洋水域面积的演变情况。分析显示,由于沿岸围垦造陆,近30 a间,伶仃洋水域面积出现了很大程度的减小,减小幅度最大的年份出现在1988～1995年间。在此基础上,计算和分析了近30 a来伶仃洋水域纳潮演变情况。
Based on the available research data and achievements, the historical evolution of watershed area and coastline in Lingdingyang Sea was analyzed and summarized. The remote sensing data were used to accurately calculate the evolution of the watershed area within the Lingdingyang Sea in the past 30 years. The analysis shows that due to the reclamation and land reclamation along the coast, the area of the Lingdingyang waters has been greatly reduced over the past 30 years, with the largest decrease occurring between 1988 and 1995. On this basis, the evolution of the tide-free tide in Lingdingyang waters in the past 30 years has been calculated and analyzed.
