The results showed: (1)The level of urban land intensive use of Anhui Province constantly improved from 2004 to 2009, increasing more than 2 times of the intensive land-use level; (2)the level of urban land intensive use had significant regional differences, the south of the Huaihe River cities having the higher level, and the north of the Huaihe River cities having the lower level; (3)economic development level is the most important external factor affecting the level of urban land intensive use. The level of urban land intensive use is higher in developed areas, such as Hefei , Ma Anshan and Wuhu than other areas.
