摘要
亚热带季风区风沙化土地的风沙地貌特性,与中国北方沙漠化土地的风沙地貌和海岸沙丘均有明显的不同。在深入调查和解剖沙堆沉积构造的基础上,恢复其发育过程,提出各种风沙地貌类型的发育模式。并通过对影响风沙地貌发育的各种因素的分析,提出该区风沙地貌发育的有限性。
Taking Houtian as an exampl,the featares of eolian sand landforms in subtropical zone of China are discussed in ditail in addition to the process of landform development. Through analysis to the factors that affect the development of landform,a model was set out. The reason why the wind-sand impacted land can be existed here is due to strong wind and dry climate in winter, which cause sand drift on sandy ground and form various brush dunes. Since sand source is not abundant, the scale of land-form here can not develop as large as in the desertified areas of Northern China, According to the field investigation, the land form scale has nearly reached summit, most probably it would decline in the future.
