It covers an area of . By size it is the third largest desert in China. This desert is home to some of the tallest stationary dunes on Earth, with some reaching a height of more than , although most average at around . Its tallest dune is also measured, from base to peak, as the world's third tallest dune and highest stationary dune in the world. The desert also features over 100 spring-fed lakes that lie between the dunes, some of which are fresh water while others are extremely saline. These lakes give the desert its name which is Mongolian for "mysterious lakes". It is also crossed by one river, the Ruo Shui ("weak water"), which has formed an alluvial plain in the desert.〔(【引用サイトリンク】url=http://www.appletravel.cn/holidays/attractions.php?id=13 )〕 ==Geography== Measuring over , the Badain Jaran Desert covers a significant part of the south-central part of the Inner Mongolia Autonomous Region as well as the North part of Gansu province. Located in the Alxa Plateau at about 1200 meters above sea level it is listed as a subsection to the Gobi Desert. It is bound to the north by the Gobi and to the East by Mount Lang which separates it from the Ulan Buh Desert (Pinyin: wū lán bù hé shā mò Chinese: 乌兰布和沙漠) Although most of the dunes in the desert are not stationary, the larger ones usually ranging above are static. With these dunes only the shallow surface of the sand is constantly shifting. The middle and lower layers of the highest dunes have been compacted for more than 20,000 years causing the sand particles to harden resulting in solid layers of sand and sandstone. High moisture levels inside the dunes also contribute to maintain their fixed state. This rigid structure also allows peaks, cliffs, gullies and even caves to form as a result of water erosion and desertification. The Badain Jaran Desert, like the Tengger Desert which lies to the east (and with which the Badain Jaran Desert is currently merging due to extensive desertification) is about one-half barren, sandy desert and one-half a mixture of solid bedrock and loose gravel. Several small lakes and oases scatter the desert around which limited vegetation is able to grow.〔(【引用サイトリンク】url=http://www.foreignercn.com/index.php?option=com_content&id=7939:badain-jaran-desert&catid=39:inner-mongolia&Itemid=123 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Badain Jaran Desert」の詳細全文を読む スポンサード リンク
