- Abstract:
- Based on the land use data of each county from 1996 to 2013, we introduced the concept of information entropy, equilibrium degree, dominance index and Lorenz curve to analyze the land use structure in Aksu Prefecture. The land use structure allocation of seven major land use types in 9 counties was studied in Aksu Prefecture, which is of great significance to guide land use reasonably and sustainable development of land use. The conclusions are drawn as follows. (1) The information entropy of land utilization in Aksu Prefecture differed distinctly, which could be divided into three regions such as high information entropy district, middle information entropy district and low information entropy district; equilibrium level of land use structure increased gradually in pace with the three regions. (2) The most unbalanced lands were the unused land, the forestland and grassland, followed by the garden land and urban village and industrial land and unused land, the transportation land and the cultivated land were balanced over time; the unbalanced degree of grassland decreased, while those of the cultivated, garden, forest, urban village and industrial, transportation and unused lands exhibited an opposite trend. Thus, the distribution of seven major land use types is temporally and spatially unbalanced in Aksu Prefecture. This result can be helpful for structural optimization of land use in this region.
