2006年胶州湾现有水域面积与岸线的卫星调查与历史演变分析

The Satellite Investigation on the 2006 Water Area and Coastline Length of the Jiaozhou Bay and Their Historical Evolution

利用2006年5月20日Landsat-5 TM卫星数据对胶州湾的现存水域面积与岸线长度进行了量算,结果给出胶州湾2006年现存总水域面积为353.92 km2,总岸线长度为220.02km。与历史数据进行比较发现,总岸线长度在进一步加长,而总水域面积在进一步缩小。其原因是由胶州湾的人工围垦所致。

The present water area and the coastline length of the Jiaozhou Bay were measured by using Landsat-5 TM image acquired on May 20, 2006. It has been shown that the total water area and the total coastline length existing in the Jiaozhou Bay in 2006 were 353.92 km^2 and 220.02 km respectively. Comparing with the historical data, it has been found that the total length of the coastline is increased further and the total water area is decreased further. This is considered to be resulted from the artificial reclaiming of the Jiaozhou Bay.
