The nature reserve
is animal type, with an area of 4 million
hectares. The main protection objects
of the nature reserve are black-necked
cranes and wetland ecological system.
Set up in 1993, Xainza Nature Reserve
lies in Xainza County of Nagchu Prefecture,
north of Tibet Autonomous Region, where
there are many lake-basin belts. Because
its location is in south somewhat and
the sea level is lower than the north
and middle of Qiangtang Highland, the
temperature there is a little high and
little amount fields can be planted
in Qingke. The rainfall of there in
a year is 300 millimeter. Owing to the
supply of thawy glacier and snow of
Gangdisi Mountain, the mineral containing
of the lake water is low, especially
the grass and inner rivers forming good
inner wetland and water ecological system,
for the water substance and water birds
to develop and live. So, the nature
reserve becomes the ideal place for
the black-necked cranes to rest and
also becomes the highest at sea level
and biggest in area nature reserve in
seven nature reserves for black-necked
cranes protection.
