| 本研究基于1984～2016年间的3个时期遥感影像及潮汐潮位资料，利用相同潮位对比法，分析了胶州湾潮间带的面积及质心的空间分布特征和动态演变规律.结果表明，近30a来胶州湾潮间带减少明显.1984～2001年潮间带面积减少了52.80 km2，2001～2016年潮间带面积减少了8.10 km2.潮间带质心偏移最明显的区域为黄岛地区.1984～2001年该区域质心向东南方向偏移量达1 061.48 m；2001～2016年该区域质心向东北方向偏移达2 881.64 m.在不同时间段内，引起潮间带面积和质心变化的原因并不相同.1984～2001年潮间带面积的减少和潮间带质心位置的偏移主要是由海水养殖规模的扩大和盐田的建造引起的；而2001～2016年潮间带面积的减少和潮间带质心的偏移主要是由于盐田、养殖池废弃，代之以大规模的填海造陆活动引起的；除此之外，河口泥沙淤积、冲刷等现象也对潮间带面积的变化和潮间带质心位置的偏移产生了一定的影响. |

| Abstract: |
| Based on three scenes of remote sensing data from 1984 to 2016 and tide and sea level data，the spatial distribution and the changing process of tidal zone's area and centroid in Jiaozhou Bay were analyzed applying the method of "same sea level contrasting". The results show that firstly the tidal zone area is decreasing. From 1984 to 2001， the tidal zone area in Jiaozhou Bay has decreased by 52.80 km2 and from 2001 to 2016 it decreased by 8.10 km2. Secondly， the centroid of tidal zone has offset severely， among which the centroid of tidal zone of Huangdao offset the most. From 1984 to 2001， the centroid transferred 1 061.48 m from northwest to southeast continuously. Compared with 2001， the area of tidal zone in 2016 has offset 2 881.64 m northeastwards. Thirdly from 1984 to 2001， large-scale aquaculture， salt pan activities and smallscale sea reclamation were responsible for the reduction of the tidal zone's area and the deviation of tidal zone centroid. From 2001 to 2016， large areas of salt pan and aquaculture pond have been abandoned due to large-scale land constructions. Besides， the erosion and deposition has also contributed to the changes of the area and tidal zone centroid in Jiaozhou Bay. |
