Analysis on the influencing factors of land intensive use in Nanjing based on gray correlation and entropy method

Based on gray correlation method, taking Nanjing as an example, selecting the data of the influencing factors of land intensive use from 2005 to 2011, using entropy method to calculate the index weight of each factors, this study analyzes the influence degree of different factors on the land intensive use and the disparities among them to provide the relevant departments with the scientific basis for making policies to promote the land intensive and efficient use. Key words: land intensive use; entropy method; gray correlation method; influencing factor
