补充资料:风蚀地貌
风蚀地貌 wind-erosion landform 风力吹蚀、磨蚀地表物质所形成的地表形态。风蚀地貌的主要类型有:①风蚀石窝。陡峭的迎风岩壁上风蚀形成的圆形或不规则椭圆形的小洞穴和凹坑。大的石窝称为风蚀壁龛。②风蚀蘑菇。孤立突起的岩石经风蚀作用而成的蘑菇状岩体,又称石蘑菇、风蘑菇。③雅丹地形。河湖相土状堆积物地区发育的风蚀土墩和风蚀凹地相间的地貌形态。雅丹是中国维吾尔语,意为陡峭的土丘,因中国新疆孔雀河下游雅丹地区发育最为典型而命名。其发育过程是:挟沙气流磨蚀地面,地面出现风蚀沟槽。磨蚀作用进一步发展,沟槽扩展为风蚀洼地;洼地之间的地面相对高起,成为风蚀土墩。④风蚀城堡。水平岩层经风蚀形成的城堡式山丘,又称为风城。多见于岩性软硬不一(如砂岩与泥岩互层)的地层,中国新疆东部十三间房一带和三堡、哈密一线以南的第三纪地层形成了许多风城。⑤风蚀垅岗。软硬互层的岩层中经风蚀形成的垅岗状细长形态。一般发育在泥岩、粉砂岩和砂岩地区。⑥风蚀谷。风蚀加宽加深冲沟所成的谷地。谷无一定的形状。风蚀谷不断扩大,原始地不断缩小,最后仅残留下一些孤立的小丘,即风蚀残丘。⑦风蚀洼地。松散物质组成的地面经风蚀所形成椭圆形的成排分布的洼地。较深的风蚀洼地如以后有地下水溢出或存储雨水即可成为干燥区的湖泊,如中国呼伦贝尔沙地中的乌兰湖等。
