渤海湾近30年海岸线变迁与分析
On the Changes of the Coastline in Bohai Bay during the Last 30 Years
摘要
Abstract
The coastline of a bay is an important object to be monitored for the changes of the Bay.In this paper,the surface area of sea water in Bohai Bay,length and fractal dimension of its coastline in the last 30 years from 1986 to 2014 were interpreted by using American Landsat -5 /TM,Landsat -7 /ETM and Chinese HJ1A,B /CCD remote sensing images.The results showed that the sea water surface area has been decreasing with the value of 13 909.97 ±1.84 km2 in 1986 and 12 641.99 ±11.50 km2 in 2014;the length of the coastline decreased at first 12 years with the value of 968.41 ±1.84 km in 1986 and 642. 43 ±2.59 km in 1998,and then increased with the value of 850.94 ±10.78 km in 2014;The fractal di-mension decreased from 1.110 2 in 1986 to 1.064 9 in 2014.The results also showed that sea reclama-tion,the construction of marine farm and port were the driving factors of the changes of the coastline in Bohai Bay;the fractal dimension was correlated with the reciprocal of the Gross Domestic Product (GDP) of Tianjin Municipality linearly with the linearly correlation coefficient of 0.95.The results of measure-ment and analysis could be a reference for dynamic research of a bay and,changes of environment evalu-ation and management of bay development.关键词
