Abstract:: The ecological security of cultivated land is directly related to grain production, and food production is a major policy issue related to the harmonious development of society. In order to provide theoretical guidance and decision-making reference for the regional food security and promoting the coordinated development of the regional grain production, the study on the ecological security of cultivated land in Sichuan Province was carried out. We took the Sichuan Province as the study area of the important commodity grain base in Western China. Based on the dissipative structure theory, the mathematical model was used to analyze the ecological security level and evolution trend of cultivated land in the period from 2000 to 2013 in Sichuan Province, and to explore its influencing factors. The results show that:(1) the ecological security level of cultivated land in Sichuan Province is more secure in 14 years; (2) the ecological security situation of cultivated land in the period from 2000 to 2008 was in the trend of improving year by year, and the security situation of cultivated land in the period from 2008 to 2013 slightly decreased; (3) the main influencing factors are the socioeconomic pressure factors, the agricultural science and technology factors and the ecological environment factors. So, it is necessary to enhance the publicity of cultivated land protection and the farmers’ consciousness in ecological protection, to carry out the ecological safety restoration for cultivated land, and to establish a monitoring network system on ecological safety of cultivated land based on the internet plus.
