摘　　要：深港交界处的深圳湾具有重要的生态价值。在收集历史海图资料、近期实测地形资料和卫星遥感影像的基础上,对深圳湾的河床演变特征和岸线变化进行了分析。分析结果表明,深圳湾近百年间河床不断淤浅、纳潮量逐步减小;20世纪80年代以来,随着深圳侧大量围海造地,深圳湾岸线向湾内大幅度推进;现状边界条件下,深圳湾持续淤积的趋势不会改变。研究了深圳湾河床演变对湿地生态系统的影响,包括滩涂面积变化、沿岸滩涂淤高对红树林的种群、分布变化以及底栖动物、水生生物、鸟类的栖息繁衍等造成的影响,并就保护湿地生态系统提出了建议。The Shenzhen Bay is located on the boundary area of Shenzhen and Hongkong and has important ecological significance. Based on the analysis of the historic chart material, recent actual measured topographic data and the satellite image, the river bed evolution and coastline variation of the Shenzhen Bay was analyzed. The analysis showed that the silted river bed has become increasingly shallow and the tide was reducing in the past 100 years. Since the 1980s, the reclamation on the side of Shenzhen caused the deep receding of the coastline into the bay. The trend of the sediment will remain with the recent boundary conditions. The effects of the river bed evolution was studied on the wetland ecological system, including the catchment area of the shoal, the mangrove species and the habitats of the zoo benthos, the aquarium and birds. And the suggestions were figured out to protect the wetland ecological system.
