摘要/Abstract

摘要： 舟山十六门8个无居民岛位于舟山高强度开发海域,根据1962、2002和2012年3期水深地形数据,利用GIS软件分析了十六门诸岛区域岸滩的冲淤变化。结果显示:1962—2002年的40 a间,研究区处于缓慢淤积态势,年均淤积速率为5.3 cm/a;2002—2012年的10 a间,研究区由淤积变冲刷,年均冲刷速率为52.7 cm/a。据分析,2002年以后,研究区周边海域高强度的人类开发活动引起的叠加效应是造成研究区水下岸坡快速冲刷的主要原因。

关键词: 无居民海岛, 海岛开发, 冲淤变化

Abstract: Eight uninhabited islands of Sixteen Door are located in the Zhoushan sea area with a high-intensity development. Base on the bathymetric data of 1962, 2002 and 2012, GIS technology was applied to analyze the beach scouring and silting in this region. The results indicate that in the past 40 years from 1962 to 2002, the sediment had been silted up in the study area with the rate of 5.3 cm/a. However, it presents an adjustment from slow silting to rapid scouring in the recent decade from 2002 to 2012, with the annual erosion rate of 52.7 cm/a. According to the analysis, since 2002, the combined effects of the intensive human activities in the study area and its vicinity are the main reason for rapid sediment erosion of the underwater slope.

Key words: uninhabited islands, island development, scouring and silting
