Baoji City develops much faster recently, and much progress has made on urbanization. On the other hand, urbanization has been closely linked to use of land resources, for city expansion relies on lands. According to the 6th demographic census of Baoji and land survey in 2009, the research analyzed problems in urbanization of Baoji and concluded that urbanization proceeds well, as well as land intensified use. Still, the problems can never be ignored, such as poor land quality,decreasing farmland, low land use ratio and intensive use degree, slow optimization process of land use structure, more limiting factors of land development and use,heavier eco-environment protection tasks. Additionally, the research proposed specific countermeasures based on status quo of land use.
