基于已有研究成果,利用地形图、海图和遥感影像等资料,提取1863~2012年共6个年代胶州湾海岸线位置,量算5期胶州湾海域面积变化量,制作各期胶州湾海域面积变化及不同开发利用方式面积分布图。研究结果表明:在过去近150 a时间里,胶州湾海域面积减小41%,减小速率最大可达3.71 km2/a;1863年以前,胶州湾海域面积变化完全受自然因素控制;1863~1935年,自然因素是主控因素;1935~2012年,人类活动是主控因素;1863~2012年,填海造陆等开发利用方式导致的胶州湾海域面积变化数量逐期增加。
Based on the existing research results, using the topographic maps, charts and remote sensing images, we extracted the coastline of the Jiaozhou Bay from 1863 to 2012 and calculated the change of the area of the Jiaozhou Bay in the 5th period and the area of the Jiaozhou Bay Changes and different development and utilization of the area distribution map. The results show that in the past 150 years, the area of Jiaozhou Bay decreased by 41% and the maximum rate of decrease was 3.71 km2 / a. Before 1863, the area change of Jiaozhou Bay was completely controlled by natural factors; from 1863 to 1935 In the years from 1935 to 2012, human activities were the main controlling factors. From 1863 to 2012, the change of the area of Jiaozhou Bay caused by the development and utilization of land reclamation increased gradually.
