摘　　要：特殊的地理位置,区域地质背景及气候条件形成了阿拉善丰富的地质遗迹资源,主要地质遗迹有沙丘(沙山)、沙波纹,沙漠湖泊、戈壁、峡谷、花岗岩风蚀地貌、阿拉善奇石等,阿拉善沙漠地质公园是目前国内外唯一以沙漠地质遗迹为主的国家地质公园。文中对阿拉善沙漠地质遗迹资源进行了全球对比分析,结果表明:阿拉善地质遗迹主要有沙漠分布面积大、景观丰富,沙漠湖泊多、水源条件好,鸣沙区面积广,高大沙山分布密集,与文化遗产关系密切等主要特征。在全球对比分析的基础上,提出了地质遗迹保护行动规划,认为主要应从沙漠形成演化与全球变化、沙漠地质遗迹与景观、保护与开发利用研究等方面开展科学研究,从乡土科普、教学实习等方面开展科普教育活动。提出了建立世界地质公园的构想,对其拟建地质公园概况、地质遗迹分级保护开发等进行了总体规划。Owing to the special geographical position,regional geological background and climate,abundant geoheritages are formed in Alxa desert. There are dunes,sand mountains,sand ripples,desert lakes,gobies, canyon,winderosion landforms,Alxa rare stones,etc. Alxa desert geopark is the only national geopark at home and abroad at present which has main desert geoheritages. Global correlation of Alxa desert geoheritages shows that Alxa geoheritages have the characteristics of large distribution area,many desert lakes,and better wa- ter condition,wide ringsand area,high and distributed densely sand mountains,and closely relationship with culture heritage. At the base of global correlation,the planning of protection action of geoheritages is proposed. Scientific researches should emphasize on the formation and evolution of desert and global changes,popular science education should carry out from local popular science and teaching practices activities. At last,the construction conception of Global Geopark is put forward,and general situation of Global Geopark and planning of geoheritage grading protection and development are proposed.
