【摘要】 使用网格法以1987—2006年间5景经过精确校正的Landsat-TM遥感图像为基本资料,计算出了胶州湾海岸线的分形维数,其值为1.0901(1987年),1.0903(1992年),1.0829(1997年),1.0762(2003年)和1.0801(2006年)。结果表明,1987—2006年胶州湾海岸线分形维数先后经历了缓慢增大、减小、再增大的三个变化阶段。胶州湾较大规模的海岸工程是其岸线分形维数减小的主要原因,而较小规模的海岸工程和自然过程则是其分形维数增大的原因。更多还原

【Abstract】 Based on Landsat-5 TM remote sensing images which were precisely corrected and obtained from 1987 to 2006,the fractal dimensions of the coastline of the Jiaozhou Bay were calculated by means of a gridding method.The values thus obtained are 1.090 1(1987),1.090 3(1992),1.082 9(1997),1.076 2(2003) and 1.080 1(2006) respectively.The results indicate that the fractal dimensions of the coastaline of the jiaozhou Bay had changed in three stages from 1987 to 2006,that is,slowly enlarged first,then lessened,and afterward enlarged again.The lessening of the fractal dimension may be caused by large-scale coastal engineering programs and the enlarging ones may be due to small-scale coastal engineering programs and /or natural processes.更多还原
