In order to explore the land ecological security situation of industrial transfer demonstration region, on the basis of the concept of land security and driving-pressure-state-impact-response model, the land ecological security evaluation indicator system was established. Analytic hierarchy process(AHP)and quotient method were applied to determine the weight of indicators. Matter-element analysis method was used to build the comprehensive evaluation model of land ecological security evaluation, and Hefei City was taken as an example for the case study. Through analysis, we draw the following conclusions. The land ecological security level of Hefei from 2005 to 2009 and 2011 was insecurity, it was less security in 2010, and was critical security in 2012. Overall, the trend of land ecological security in Hefei city zoomed from insecurity to critical security. The conclusion could be used to provide theoretical basis for the social and economic sustainable development under the situation of industrial transformation in Hefei city.
