The northwest region in China is considered to be one of the worst regions in shortage of water resources. The shortage and
irrational exploitation of water resources have become a major factor for limiting sustainable development of the region’s economy and
society. Based on analysis and evaluation of the present situation of water resources and its utilization in northwest China, this paper
suggests that establishing water-saving society is the key to achieving sustainable utilization of water resources in the region. The
key strategies for promoting the establishment of water-saving society are to (1) establish and perfect administrative system, market
-oriented system and legal system for water resource management; (2) set up target system for scientific utilization of water
resource; (3) adjust agricultural structure to form a water-saving agricultural system; and (4) adjust industrial structure to establish
a water-saving industry system.
