摘要
对唐山市1979-2012年以来5个不同时期的遥感数据进行解译,结果显示33年间海岸线长度增加了81.8 km。岸线变化主要受人类活动的影响,其变化对应了经济发展的三个时期:1979-1991年是海洋工业和海水养殖业从起步到迅速发展的阶段,盐田、养殖池等人工堤坝岸段快速增长;1991-2000年是港口发展起步,海洋工业和海水养殖业平稳发展的阶段,各类岸线长度增长缓慢;2000-2012年是曹妃甸区、唐山港等重大工程建设迅猛发展的阶段,港口岸线迅速增长。受海岸线变化的影响,唐山沿海沙坝—泻湖地貌体系遭到了破坏,曹妃甸海域海洋水动力条件发生了改变。预测至2020年,在沿海经济开发的影响下唐山市海岸线长度将继续增加。
The research interpreted the five different periods of remote sensing data from 1979 to 2012 in Tangshan, and the results showed that the coastline length had increased 81.8 km in 33 years. The shoreline changes which were affected by human activities mainly corresponded to the economic development of three periods from 1979 to 1991, the marine industry and aquaculture were from the beginning stage to the quick developing stage, while the artificial coastal embankment such as salt fields and culture pond increased rapidly;from 1991 to 2000, the port was in the primary step of development, and the marine industry and aquaculture were in the stably developing stage, while the embankment increased slowly;from 2000 to 2012, the major projects such as Caofeidian industry park and Tangshan port developed rapidly, while the embankment increased quickly. Affected by the shoreline changes, the barrier-lagoon system along the coast in Tangshan was damaged, and the marine hydrodynamic conditions in Caofeidian sea area changed. It was estimated that the coastline of Tangshan would continue to increase with the costal economy development up to 2020.
