The Structure Changes of the Land Use and the Related Influence Factors Analysis------based on the Information Entropy and Principal Component analysis

摘要

Using information entropy, this paper analyzed the temporal and spatial variation of land use structure in Shandong Province from 2003 to 2008. The results are as follows.- The information entropy and equilibrium degree went up and the dominance degree went down year by year. That reflects that the disorder of the land use system was strengthening, while the structure weakening, and that the types of land utilization tended to be equilibrium during the study period.
