Abstract: The potential economic, social and ecological risks existing in land use transitions will affect the sustainable development of the Middle of the Yangtze River Economic Belt, thus it is critical to develop a method of assessing the risks of land use transition. In this paper, firstly, a risk assessment index system was built based on pressure-state-response (PSR) model. Then entropy-TOPSIS (technique for order preference by similarity to ideal solution) was adopted to assess the current risks of land use transitions. Subsequently, the critical factors of the risks were identified by means of obstacle degree analysis. Finally, the trend of economic, social and ecological risks in the Middle of the Yangtze River Economic Belt from 1990 to 2015 was assessed and analyzed, and the risk factors in each risk stage were found out. The results of the present study could promote the research progress of the risk assessment of land use transitions in the Middle of the Yangtze River Economic Belt.

Key words: the Middle of the Yangtze River Economic Belt, land use transition, technique for order preference by similarity to ideal solution (TOPSIS), risk assessment, factors identification
