Abstract：In order to further define the status of land eco-security in Sichuan province ,the land eco-security evaluation index system was constructed based on the model of nature-economy-society ,and the land eco-security correlation was studied by employing the matter-element model in the years of 2004 ,2006 ,2008 ,2010 .The results showed that the land eco-security level of Sichuan province was improved from 2004 to 2010 .The land was in critical safe state in 2004 and 2006 ,but compared with 2004 ,the land eco-security level in 2006 decreased because of drought disaster ;The land was in relatively safe state in 2008 and 2010 .Comprehensive analysis showed that ,enhancing the ability to resist natural disasters ,strengthening the pollution abatement and ecological environment protection were the keys to improve land eco-security level of Sichuan province .
