2010-2017年珠江河口海岸线遥感监测和动态变化分析
|
摘要
海岸带是受全球气候变化及人类活动影响最大的地带。本文主要依托谷歌地球平台提供的时序高分辨率卫星遥感影像,提取了2010-2017年珠江河口地区海岸线信息,对不同时期的海岸线长度、类型及围海造地面积的变化情况进行了统计分析,对引起变化的驱动机制进行了探讨。结果表明:(1) 2010-2017年珠江河口海岸线呈现先减少、后缓慢增长趋势。2010-2011年由于海面整治工程,海岸线长度略微缩减,2011-2013年为快速增长阶段,2013年后海岸线长度变化不大,略微呈现增长;(2)在基岩海岸线、砂砾质海岸线、淤泥质海岸线、人工海岸线、生物海岸线五种海岸线类型中,人工海岸线最长,占总长度的比例始终在85%以上,年均正向变化强度最大,达到0.28%,呈现稳定扩展趋势;淤泥质海岸线的负向变化强度最大,为-0.28%,呈现稳定萎缩趋势;(3)围海造地面积呈增加态势,年均变化面积为0.25 km~2;引起围海造地面积增加的主要原因为港口和码头建设。
The coastal zone is the region most affected by global climate change and human activities. Mainly supported by the time-series high-resolution satellite remote sensing imagery provided by Google Earth, the coastline information of the Pearl River Estuary in 2010-2017 was extracted, the length, types and area of land reclamation in different periods was summarized and analyzed, and the driving mechanism which caused the change was also explored. The results show that:(1) The coastline of the Pearl River Estuary decreased first and then slowly increased in 2010-2017. During 2010-2011 the coastal length reduced slightly, then increased rapidly from 2011-2013, and remains basically unchanged after 2013.( 2) Among all five coastline types( bedrock coastline, sandy coastline, muddy coastline, artificial coastline, biogenic coastline) the artificial coastline is the longest, always accounting over 85 % of the total length; the annual change intensity is the highest positive, reaching 0.28 %, showing a stable expansion trend; while the lowest negative change intensity of the muddy is -0.28 %, showing a stable shrinkage trend.( 3) The area of land reclamation was increasing, with an average annual change of 0.25 km~2. The main reason for the increase is the construction of ports and terminals.
