英文摘要Based on the results of field surveys,the spatial and temporal dynamics of sandy coastal geomorphology along the eastern Laizhou Bay over the last 60years was investigated using the comprehensive methods of digital shoreline analysis,remote sensing and geographic information system technologies.The data mainly derived from the nautical charts,topographic maps and high resolution remote sensing images which measured and imaged in different periods.The results show that there are significant spatial-temporal variations in both the sandy coast shoreline migration and the subaqueous slope erosion-deposition evolution along the eastern Laizhou Bay.The alternate regulation of forward and backward for shoreline migration is caught in this study.There is a remarkable non-linear characteristic in the time process.The proportion of the erosional shoreline is fluctuated and phased from 1959to 2013.The average annual evolution rate of eroded coast is divided into two stages by 1985.The erosion rate decreased from the maximum value of 4.95m/a(during the period of 1959-1969)to minimum value 1.97m/a (1969-1985)at prophase.In the late period,the erosion rate increased from 1.97m/a to 4.43m/a(1985- 1998),and the coast was in serious erosion state since then.The characteristics of shoreline migration in four headland bays are not consistent with overall trend.At the same time,the scouring strips distribute alternating with the silting of the subaqueous slope.The trend of scouring and silting evolution was basically opposite in the same coast between the periods of 1959-1985and 1985-2008.Further analysis indicate that there are 5alternations of erosion and deposition and the changes of rate of erosion and siltation,under the control of geomorphic effects of anthropogenic activities such as sediment trapping by reservoirs,fishing culture in supratidal zone and coastal engineering, in the east of Laizhou Bay during recent 60years.
