Process and Structure of Land Use/Land Cover Change in Oases: A Case Study of Tianshan Mountains Northern Slope, Xinjiang, China

Taking the Northern Slope of the Tianshan Mountains (NSTM) as the study area, we investigated into the oases LUCC and information entropy change by using RS, GIS and statistical model. The results showed that, (1) Establishing mathematical models of the range, speed and trend index of LUCC, especially the model of LUCC trend and state, the state and trend of oasis LUCC can be deeply researched. Meanwhile, land use system had changed from the quasi-equilibrium state into a equilibrium state. (2) Information entropy change models reflected the orderliness and structure of regional land use system. Land use information entropy has shown a steady downward trend in the past 50 years. Land-use system is increasingly orderly at the same time. However, the orderliness and structure of the land use system in NSTM was still below the national average. (3) LUCC had a great impact on regional land use information entropy change. This paper is a right example for it.
