Spatiotemporal structural evolution and regional differentiation analysis of land use in Xinjiang based on information entropy

Through applying data of land use extracted from remote sensing image at the end of 1980s, 1990s and 2005 in Xinjiang. The information entropy and equilibrium degree of land use spatial-temporal structure are calculated based on Shannon entropy theory. Trends of changes and spatial of land use structure are studied on time and space in xinjiang as a whole, Characteristics and rules of 1and use spatial-temporal structure evolution are dicussed in detail. Some results are concluded as follows: The land use information entropy in Xinjiang was creased gradually from 1989 to 2005, and, in 1999~2005, the land use information entropy increment was greater than in 1989~1999, the whole land use in Xinjiang was at developing period, the development in 1999~2005 was greater than in 1989~1999. From space to see, land use structure information entropy existed obvious difference, the entirety rule is: north information entropy value is higher than south, west information entropy value is higher than east.
