Main scenic spots of Juyan Sub-park
Black Gobi in Ejin
The name of Gobi, which origins from Mongolian, means “the land of no grass”. It is the desert landform which covered by coarse sand and gravel and the surface is flat. It is divided into gravel Gobi of weathering and water-ecliptic and grit Gobi of erosion. Most of the Gobi in this subpark is “Black Gobi” , which is distributed in the east of Mount Mazong and the west of Ejina River. Mass of gravels, with edge-angled and shiny-black enamelled leather which is named of “Gobi Paint”, spread over the ground surface. Gobi gravel mainly originates from diluvial and native rock weathering.
Transition belt of Gobi and Desert
Transition Belts of Gobi and Desert in NE Ejin Qi
It is considered to be an important landform transition belt from desert to gobi. Although the width of the belt is not very large and the two distinguished geomorphic elements are easily to be observed here. The northernmost part of the edge of mobile dunes in Badian Jaran Desert is connected with Gobi. Lots of melanocratic minerals are observed in the desert, which indicates a low maturation degree. The north edge of the desert is Gobi. The ground’s surface is relatively flat. The majority of the gravels there, which originate from native rock weathering, with shiny-black and low-psephicity rough surfaces and bad rounding, have complex components and an average particle diameter of 1-2㎝. The Gobi is on the gravel-desertification period.
Wonder stones of Gobi
Wonder stones of Alxa
Wonder stones of Gobi belong to rillstone, including the type of crystal, agate, chalcedony, opal, silicede and etc., the main ingredient is siliceous, distribute in the northern part of Gobi in Alxa Zuoqi.
Since 1.37 billion years the late Juraasic ago from now, it occurred a largr scale outpouring of basalt magma. Lava flows poured out from the Earth crust, in the process of condensation, carbon dioxide, water vaper escaped rapidly, forming basalt with many holes. In the late stage of volcanic activity, the hydrothermal full of silica invaded, and quickly into the porous rocks, after the cooling could form agate, jasper, opal, quartz and other individuals. After a long time weathering, the part of weak anti-weathering got erosion, the residual are the toughest silica which form the surprising and gorgeous wonder stones.
Spot2： Juyan Lake
Waterbirds stay in Juyan Lake
Juyan lake, called as “Nanhai lake” in the early stage , is made up of three parts: East Juyan lake, West Juyan lake and Jingsitu lake. In 1961, the west Juyan lake dried up, so did the East Juyan lake in 1992, which is brought the environment deterioration in the large scale. Under the care of the State Council, the Juyan lake gains water transported from other place and the environment is well improving. “Small Juyan lake, collecting the Zhongnan lake” is the best description which represent the relation of central government and local government. The scenery of the Juyan lake is spectacular.
Lake erosion terraces
There are lake erosion terraces in Juyan Lake area.The first terrace of Juyan lake is dominated by sandy and shaly clastic sediments, and low crystallinitied silicalite outcrops in the second terrace. The height of the first terrace is about 1m, and the second terrace is 2-3m. The terraces were probably formed in Late Pleistocene epoch which is 128,000 years ago. Neotectonic movement caused the intermittent rise of earth crust, and formed the second lake shore terrace. It indicates that in historical period, the extent area of Juyan lake should be much larger than it is today.
Populus euphratica Forest
Populus euphratica
Populus euphratica,the oldest poplar breed in the world, is also called poon, and has been named “lived fossil tree”. Populus euphratica belong to the defoliate arbor and live near the water. It is able to bear saline-alkaline, and grows quickly. It has very strong vitality, “live but not dead for 1000 years, or dead but not fall for 1000 years, or fall but not decayed for 1000 years” is the symbol of the Mongolian spirit.
Dead populus euphratic forest
Dead populus euphratic forest
Dead populus euphratic forest is result from the populus euphratic dying of lack of water. Populus euphratic that have ever been flourish become “dead” all over the field, or become dried trunk , or merely have “a little life”. The scene is tragic and it is like an old battlefield that had a fierce flight, just like unbending soldiers in the black city. In fact, it is the result from the descending water level and the drought weather. Dead forest has become an “alarm forest”. It has knolled the alarm bell to human that we have to pay attention to the protection of ecological environment.
