Analysis on land use coordination degree is instructive to land intensive use and land sustainable use. The coordination is established to analyze the land use coordination degree of Nanjing from 1999 to 2008; on the basis of this, coordination factors are analyzed by the multiple stepwise regression. The result shows that land use coordination degree in Nanjing has been in a rising trend in the recent ten years, but there is still a distance from the full coordination; we find that the main factors of land coordination use are population growth, economic development and the level of afforesting.
