摘要

This paper established the comprehensive evaluation system of urban land intensive use from land use investment and output benefit, land use intensity and land use ecological benefit etc. Based on the statistical data of land use, using principal component analysis, this paper made comprehensive evaluation on the intensive land-use level of 17 cities in Anhui Province from 2004 to 2009, analyzed the changing situation in space and time. 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.
