Abstract:

The information entropy values are of guiding significance to the regulation of the land use structure in a region because they can reflect the dynamic change and transformation degree of land use types in a region in a certain period of time. The land use dynamic change is the global topic, the structure change of land use is the result of the land use dynamic change. The applications of the information entropy values of the land use structure and cointegration theory, Granger causality test are discussed in the paper. The result shows that: firstly, the information entropy of land use structure reflects the spatial temporal land use situation in Xinjiang. The information entropy rises slowly with the lapse of time, its change scope is small. Xinjiang land use structure is overall stable, but differences between Southern and Northern Xinjiang, land use differences are significant; secondly, the land use change and economic development is closely related. The variables of land use and economic development are nonstationary time series. The cointegration relation has also been found between land use and economic development in Xinjiang. Economic development is the land use changes one way Granger causes. The economic development is the main reason of the land use and type change, special natural ecological environment in Xinjiang should arrange various lands overall and coordinate between the economic development and the land use based on protecting the ecological environment. Therefore, we must make the adjustment and optimization of the land use structure in this region to maintain the regional system's stability.
