Investigation and evaluation of soil and water resources in Minqin Oasis indicate that the proportion of grain crop, cash crop and grass is 36.94:45.16:17.90 for 2005. And a comparison with that for 1991 indicates that land use structure is developing towards rational proportion of grain crop, cash crop and grass; and harmony among agriculture, stockbreeding and forest. The main limiting factors of land resources are water, soil quality, salinity and fertility, and there is about 3.9218×10^8 m^3 water deficit per year in Minqin Oasis.
