摘要 本文以高分辨力卫星遥感资料(TM861105,TM881025)为依据,量算胶州湾现有总水域面积和总岸线长度,给出历史变迁趋势。结果表明,胶州湾现有(1988年,下同)总水域面积为(390±7)km^2,近60年(1928—1988年)来缩小170km^2;1971年以来缩小62km^2,其中1986—1988两年间急剧缩小13km^2。胶州湾现有总岸线长度为(207±1)km,20年来呈增长趋势,总增长20km,其中1986—1988两年间急剧增长15km。变化最大的岸段为西北和东北部。 Based on satellite remote sensing images with high resolution, the existent total area covered by water and total length of coastal line of the Jiaozhou Bay were measured and calculated in this study. The results indicate that the existent total area covered by water of the Bay is (390±7) km2. The area has decreased 170 km2 since six decades ago. The decrement of the area from 1971 was 62 km2 and 13 km2 from 1986 through 1988. The existent total length of coastal line of the Bay is 207±1 km showing an increment tendency since two decades ago. The total increment was 20 km. The length increased sharply by 15 km during the period from 1986 through 1988. The coastal sections changed mostly on the northwest and the northeast of the Bay.
