| 以山东半岛北部为研究区，以烟台、蓬莱、龙口和莱州4个港口的潮情为依据，分别选取1984、1995、2005、2010、2015年的Landsat系列遥感影像，分析了山东半岛北部滩涂（含潮上及潮间带）及海岸线30a来的变化.研究结果表明：（1）研究区近30a来滩涂面积减少300.66 km2，其中潮间带面积减少了84.84 km2，潮上带面积年减少了215.82 km2，减少区域主要集中在莱州湾东南部；（2）海岸线长度呈递增趋势，30a来增加103.68 km，增长速度为3.34 km/a，增加典型区集中在莱州太平湾、龙口人工岛群、蓬莱港和烟台港等区域；（3）通过实地调研发现，盐田、养殖池的大量扩建、海岸侵蚀和入海泥沙量减少是滩涂减少的主要原因；沿海养殖池的增加和填海造陆的扩张是海岸线长度增加的主要原因. |

| Abstract: |
| Based on the tides of four ports in Yantai, Penglai, Longkou and Laizhou, the remote sensing images of Landsat series in 1984, 1995, 2005, 2010 and 2015 were selected and analyzed in Shandong Peninsula. The changes of tidal flat (including supratidal zone and intertidal zone) and coastline in the northern Shandong Peninsula in recent 30 years were analyzed. The results showed that the tidal flat area was reduced by 300.66 km2 in the past 30 years, including intertidal area reduced 84.84 km2, supratidal zone reduced 215.82 km2, and the area was mainly concentrated in the southeastern part of Laizhou Bay. The length of the coastline was increasing and it increased by 103.68 km in 30 years with the growth rate 3.34 km/a. The typical increased areas were concentrated in Laizhou Taiping Bay, Longkou artificial island groups, Penglai Port and Yantai Port. It is found that the expansion of salt pan and aquaculture ponds, coastal erosion and sediment reduction were the main causes for tidal flat reduction. The expansions of coastal aquaculture pond and land reclamation were the major causes for coastline length increment. |
