中文摘要：探讨改革开放近40年来深圳海岸线的变化有利于揭示其时空演变过程及驱动机制,可为岸线资源的保护和利用提供参考。文章筛选1979—2019年16景深圳区域Landsat遥感影像,基于遥感(RS)与地理信息系统(GIS)方法进行岸线提取,在保证配准精度以及提取精度达到研究要求的基础上,对深圳岸线演变时空特征、速率及驱动因素进行探讨。结果表明:1)40年间深圳海岸线长度呈现持续增加趋势,总长度增加41.52 km,平均每年增加1.04 km。其中,自然岸线总降幅达56.61%,人工岸线所占比例持续上升。2)海岸线类型主要由早期的粉砂淤泥质和砂质岸线向围垦养殖和工程建设岸线转变。3)海岸线变化经历了起始、加速和合理约束3个阶段,岸线扩张显著的地区分布在宝安国际机场、前海合作区、后海深圳湾、盐田区和龙岐湾近岸。西岸的岸线最高端点变化速率(EPR)达到422.19 m/a,出现在2004—2008年蛇口半岛的向海扩建时期;东岸的EPR最高达到449.65 m/a,出现在1994—1998年的盐田港开发建设期间。4)人类活动、特区政策和自然因素是深圳岸线变化的主要驱动因素。

外文摘要：Since the reform and opening-up,the ecological environment of the coastline of Shenzhen has been under pressure from high-intensity human exploitation activities.Additionally,the structure,type,and length of the coastline has undergone significant changes.Studying the changes of the Shenzhen coastline over the past 40 years is helpful to reveal its spatial and temporal evolutionary processes and driving mechanisms to provide a reference for the protection and utilization of coastline resources.This study screened 16 scenes of the Shenzhen regional Landsat remote sensing images from 1979 to 2019,and performed a coastline extraction using Remote Sensing(RS)and Geographic Information System(GIS)methods to ensure alignment,accuracy,and extraction precision to meet the research requirements.Based on four coastline evaluation indexes(End Point Rates,Linear Regression Rates,Coastline-type Diversity Index,and Comprehensive Index of Coastline Utilization),the spatiotemporal characteristics of the coastline length,structure,types,and rate of change were analyzed to explore the factors driving the spatio-temporal evolution of the Shenzhen coastline.The results found that over the past 40 years,(1)the length of the Shenzhen coastline has experienced a continuously increasing trend,with a total increase of 41.52 km,and an average annual growth of 1.04 km.All the natural coastlines within the coastal area of Shenzhen decreased significantly to varying degrees,with a total decrease of 56.61%,while the proportion of artificial coastlines increased rapidly.(2)The change in coastline type in Shenzhen is mainly from the early muddy and sandy coastline to the farming reclamation and engineering construction coastline,i.e.,the transition from natural to artificial shore.Among them,coastline length increased the most from 1979 to 1988.The most drastic coastline change was observed from 1979 to 1994,and the peak period of land reclamation was from 1994 to 2008.After 2008,Shenzhen coastline development gradually entered a sustainable and rational stage.(3)The spatial vicissitudes of the Shenzhen coastline have progressed through the stages of initiation,acceleration,and rational restriction.Areas with significant coastline expansion were located in Bao'an International Airport,Qianhai Cooperation Zone,Shenzhen Bay of Houhai,Yantian District,and near Longqi Bay.The change in the west coast of Shenzhen is more drastic than that of the east coast.The maximum rate of change(EPR)on the west coast reaches 422.19 m/a,which occurred during the Shekou Peninsula seaward extension period from 2004 to 2008.The EPR on the east coast reached the highest level of 449.65 m/a during the development and construction of Yantian Port from 1994 to 1998;and(4)the Shenzhen coastline change is a dynamic and a continuous process of change.Human activities,special zone policies,and natural factors were the main driving forces of the coastline changes.The special zone policy is the core driving force for Shenzhen's population expansion,urban sprawl,and the fundamental reason for the reduction in natural coastlines and the growth of artificial coastlines.This study provides important guidance for future sustainable urban development in Shenzhen.
