| 摘要: |
| 于1990-1994年，对黄、渤海海岸风沙地貌、风沙沉积、风沙灾害和土地沙漠化现象进行详细的外业调查、测量和填图。在此基础上，利用GIS技术原理，对海岸风沙地貌进行系统的分类研究，对海岸风沙地貌分布规律和发育模式进行较深入的探讨。结果表明，研究区风沙地貌、风沙灾害和土地沙漠化现象主要分布在冬、春季气候干旱、风力强而持久、砂源丰富的渤海海岸和山东半岛北岸的砂质海岸地区，海岸沙丘和风成砂地总面积达700多km2，海岸风沙地貌的发育模式受地貌背景、海岸带风场和砂源条件的控制。 |

| Abstract: |
| On the basis of the authors’ 1990 - 1994 comprehensive investigation on the aeolian geomorphical features, aeolian sedimentation, wind-sand disasters and land desertification phenomena in the coastal areas of the Yellow Sea and Bohai Sea, including field survey, mapping and measurements of wind-sand movement, the coastal aeolian geomorphical types are classified, using the principles of Geographical Information System. The distribution pattern and evolution models of coastal aeolian geomorphical types are presented and discussed in detail. The results show that the coastal aeolian geomorphical features, wind-sand disasters and land desertification phenomena are mainly distributed over the sandy coastal areas of the Bohai Sea and along the north coast of the Shandong Peninsula where sand resources are abundant and the climatic environments in winter and spring are characterized by drought weather, frequent strong winds which last for long periods. The total area covered by coastal aeolian dunes and sandy lands exceeds 700 km2; the north to northwestern winds are the direct factors causing wind-sand disasters and land desertification in the study area. The evolution models of aeolian geomorphical types in various coastal areas are mainly controlled by coastal geomorphical backgrounds, specific coastal wind regimes and sand resources. Three different evolution models of the coastal aeolian geomorphical patterns are recognized and described. |
