| 摘 要： | 根据近30年来闽江口的调查数据及文献资料,分析闽江河口区沉积特征、浅滩形态变化,以10~15年的研究尺度,探讨了闽江口的冲淤演变.提出闽江口沉积在上世纪90年代初由淤积转为冲刷的观点,揭示入海泥砂扩散和人类活动是导致这一变化的根本原因.以此警示河口侵蚀的生态环境危害,为河口区的环境治理提供借鉴.

| Abstract: | Based on the survey data and literature in the recent 30 years,the sedimentary charactristics and shoal shape changes in Mingjiang River Estuary were analyzed.The evolvement of its accumulation and erosion were discussed with a scale of 10~15 years.It is proposed that the estuary became erosion from accumulation during the early 90s of the 20th century.The causes leading to this change were from the diffusion of sediment into the sea and human activities.That the estuary erosion is harmful to ecological environment is a lesson for the estuary environmental treatment. |
