| 英文摘要 | Based on Landsat images,the spatial information of major gulfs along the coast of China in 2010,2015,and 2020 were extracted to explore the morphological change characteristics.Some evaluation indexes,such as shoreline utilization degree,gulf area,gulf shape index,and gulf centroid,were used to analyze the gulfs' spatio-temporal change features in detail.The research showed that:(1) The shoreline length and structure of major gulfs changed significantly between 2010 and 2020,and the length and retention rate of the natural shorelines decreased.(2) The development and utilization degree of the gulf increased,with the increase rate gradually slowing down,and most of the gulf was moderately developed.(3) The gulf area continued to shrink,with a slow-down shrinking rate,and the gulf area in the Bohai Sea shrunk the most and the fastest.(4) The morphological change trend of the gulf is different from north to south.The north tends to be complicated,while the south to be simple.(5) After 2015,the gulf's plane center of gravity tended to be stable,the displacement distance decreased,and the displacement velocity slowed down.Human activities,such as sea reclamation,are the dominant factors leading to gulfs' morphological change.The national policies and measures for sea reclamation management and control in recent years have initially shown their effectiveness in affecting the gulf's morphology changes.The gulfs along the coast of China should be functionally positioned and divided,with refined classified management to optimize the layout of the Ecological-Production-Living space in the gulf areas. |
