Mongolia is a land-locked
country which covers an area of 1,564,118 square kilometers in North
East Asia. It has a 3485 km border with Russia in the north and a 4670
km border with the People's Republic of China in the east, south and
west. The total area of Mongolia is larger than the combined areas of
Great Britain, France, Germany and Italy. It is one of the largest
land-locked countries and the world's seventh largest country. It is
situated between 42-50oN latitude and 88-120oE longitude.
Mountains, Rivers & Lakes
The Mongolian environment has a large variety of features. The
northern part of the country is covered by forest mountain ranges and
the southern part by desert, desert steppe, and steppe areas with low
mountains. The western part is dominated by high snow-capped mountains
and glaciers and the eastern part by vast plains and wild heaths.
About 81% of the country is higher than 1000 meters above sea level
and the average elevation is 1580 meters. The highest mountain is
Tavan Bogd in Bayan Ulgii Aimag at 4374 meters and the lowest point is
Khukh Nuur in the east at 560 meters.

Mongolia has comparatively
high levels of surface and ground water resources. The rivers of
Mongolia belong to the inland drainage basins of the Arctic Ocean, the
Pacific Ocean and Central Asia. The water network is of a greater
density in the north of the country. The longest river is the Orkhon
at 1124 kilometers in length. There are some 3000 rivers in total with
a combined length of 67,000 kilometers. There are also over 3000 big
and small lakes, 6,900 springs, 190 glaciers and 250 mineral water
springs.

Landscape
Mongolia can be divided into six zones; desert, mountain, mountain
taiga, mountain forest steppe, arid steppe and taiga. The mountain
belt of the Mongol Altai, Khangai and Khentii mountainous regions,
with their perpetual snow, glaciers, traces and signs of ancient ice
covers, has been well preserved due to a constantly cold climate and
strong winds. The area is inhabited by some endangered animals (such
as the Argali sheep, Ibex, Snow Leopard, Rock Ptarmigan and Altai
Snowcock) and plants (such as the Dwarf Siberian Pine and White
Gentiana).
The mountain taiga belt comprises about 5% of the Mongolian territory
in the Khentii and Khovsgol mountain regions in the northernmost part
of the country and experiences a relatively cold and humid climate.
Due to a brief warm period, the growing season is not long enough for
many plant species. Forests in this belt are dominated by the Siberian
Pine and the Siberian Larch and are inhabited by such animal species
registered in the Mongolian Red Book as the Musk deer, Elk, Lynx and
Eurasian Otter.
The mountain forest steppe belt extends through the Mongolian Altai,
Khangai, Khovsgol massifs and borders on the Mongolian taiga belt
which is in the southernmost fringe of the Great Eastern Siberian
Taiga. One specific feature of the Mountain Forest Steppe is that the
back of the slopes of the mountains facing the north, northeast and
northwest are covered with different species of forest and woody
plants whereas their front slopes facing the east, south and southwest
are densely covered by the steppe plants almost up to the sharp ridges
of the mountains, giving an impression of sharp habitat boundaries of
the mountain forest and steppe species. The Mountain Forest Steppe
belt encompasses 25% of Mongolia's territory and is inhabited by such
globally endangered animal species as the Manul, Black Grouse and
plants threatened by extinction such as the Mongolian Pheasant's Eye.
The Arid Steppe Zone with and area of approximately 20% of the
country's territory comprises the entire Eastern and Central Mongolian
vast flat plain extending as a tapering zone thousands of kilometers
westwards to the northwestern fringe of the Khangai mountain range
called Khankhokhii. The Mongolian steppe is part of the great plain
which starts from the Don river in Hungary and includes the Pustza,
sweeping the east up to the Manchurian steppe in East Asia. The
vegetation of the Mongolian steppe is dominated by Xerophya, Caragana
and many forms of feather grass. Mongolian gazelles can be seen
roaming and grazing in herds.
The Desert Steppe Zone includes the Depression of Great Lakes, the
Valley of Lakes and the Middle and Eastern Gobi lowlands. This area
belongs to the semi-arid zone which has an annual precipitation of
100-220 millimeters, loose soil and fewer species of animals and
plants compared to the zones, northwards. The Desert Steppe is a
habitat for such animal species as the Wild Ass, Saiga Antelope,
Black-tailed Gazelle and Houbara Bustard.
The Desert Zone is located in the southern and southwestern parts of
Mongolia and has a severe climate with annual precipitation of less
than 100 millimeters and high diurnal temperature fluctuation. The
Desert Zone is an area of extremely unique physical formations of
changing contrasts like hills, hillocks, rolling heaths, and sand
dunes. It contains deposits of ancient flora, fauna and mineral
resources, and provides a habitat for threatened animal species such
as the Wild Camel, Gobi Bear and Mongolian Agama. |
