巴丹吉林沙漠高大沙山地貌的线条美

巴丹吉林沙漠是中国第二大流动沙漠，被列入世界自然遗产提名地名录，具有独特的美学价值，但目前尚缺乏沙漠美学价值的系统论述。本文基于野外考察、影像和文献资料，将美学原理与风沙地貌学理论结合，探讨巴丹吉林沙漠高大沙山地貌的美学价值，侧重其独特的线条美。将高大沙山地貌的线条分为直线、曲线和交织线条，分别解析其美学的表现形式和所包含的科学内容。巴丹吉林沙漠高大沙山地貌的潜在美学价值值得挖掘，对沙漠资源特别是旅游资源的开发乃至沙漠科学知识的普及具有重要意义。

The Aesthetic Value of Mega-dune Lines in the Badain Jaran Desert

The Badain Jaran Desert,as the second largest mobile desert in China,has been listed in the world natural heritage tentative list for its unique natural phenomenon and rare natural beauty. However,it is lack of complete scientific discussion on the aesthetic value. Based on the field investigation,Google Earth image and literature review,we identified and classified the dune lines with the straight lines,curve lines and interlaced lines,discussing the aesthetic value of the mega-dunes with the form and content based on relevant theories of aesthetics and aeolian geomorphology. The potential aesthetic value of the megadunes in the Badain Jaran Desert is worth exploring,which is important to the development of desert resources,especially tourism resources,and even the popularization of desert scientific knowledge.
