Abstract: Evaluation of cultivated land ecological security is greatly helpful for improving the state of cultivated land ecosystem and sustainable cultivated land utilization. Taking Hubei Province as the study area， establishes an evaluation index system based on DPSIR and entropy weight method， then uses GIS technology to make a quantitative research of the ecological security level and spatial characteristics of cultivated land. The results indicate that the level of cultivated land ecological security continuously improved from 2002 to 2011. The degree of cultivated land ecological security are generally divided into two stages， which are risk-sensitive stage in 2002-2006 and critical-fairly safety stage in 2007-2011.Moran's I indicates that the level of cultivated land ecological security in Hubei Province has spatial gathered characteristics. Moran's I in 2008 is highest. The partial self correlation indexes of 17 units show the ecological security level of cultivated land of each administration unit have spatial gathered and differential characteristics. The results are important to provide scientific basis and decision- making reference for ecological security alarm and prediction of cultivated land， and can improve cultivated landsustainable utilization.
