The Maonan inhabit
Huanjiang County and its neighbouring counties of Nandan,
Hechi, Tian'e, Yishan, Du'an, Luocheng and Rongshui,
with their concentration
in the southwestern part of
Huanjiang Maonan Autonomous County on the northern
border of Guangxi Zhuang Autonomous Region.
Huanjiang is situated in the subtropical zone, covering
an area from 24º44'
north latitude and from 107º51'
east longitude, about 300 hundred kilometers north of
the Tropic of Cancer, with the annual average
temperature of 20 degrees Celsius and annual rain fall
of 1500 mm. The highest average temperature in July is
28 degrees Celsius; the lowest average temperature of
January is 10 degrees Celsius. The maximum temperature
can go up to 35 Cº,
the minimum down to 2 Cº.
It is humid in summer and relatively dry in winter. Most
villages are seated on the small strips of flat land or
slopes among the rocky mountainous
area 500–1000 meters
above sea level. Because of the higher locality than the
surrounding areas and the sinkholes and underground
caverns in the karst landform in this area, despite abundant rainfalls there are no rivers but only a small
number of streams. So water shortage has been the major
obstacle to economic development. The strips of arable
land are scattered on the slopes and on the flat
terrains in the narrow valleys, which also hinders mass
production involving large agricultural machinery.
