Abstract:: Early warning of cultivated land ecological security is greatly helpful for the cultivated land ecological security situation and food security. Taking the major grain-producing area of Xinzheng City in He’nan Province as the research object, we constructed an evaluation index system of cultivated land ecological security early-warning by employing the Pressure-State-Response (P-S-R) conceptual framework model and Ecological-Environment-Economy-Society (E-E-E-S) framework model. Introducing variable weight theory to determine the weights of all rating indices, the early-warning level of cultivated land ecological from 2001 to 2010 in Xinzheng City of He’nan Province was calculated based on improved matter-element extension model, and concluded main obstruction factors which were relevant with cultivated land ecological security by using disorder degree model. The results indicated that the overall level of cultivated land ecological security presented an upward trend from ‘early warning’ to ‘relative security’ in Xinzheng City from 2001 to 2010. The early-warning values of cultivated land ecological secutrity was appeared to the downward trend from 2009 to 2010 although level characterized as ‘relative security’. The key obstacles for further improvement of cultivated land ecological security of Xinzheng City included fertilizer load per unit of cultivated land, the multiple cropping index of cultivated land, per capita output of grain, urbanization, land reclamation rate, population growth rate, per capita possession of water resources, mulch load per unit of cultivated land, the proportion of the tertiary industry in the gross domestic product, the proportion of the agricultural economy, the proportion of unused land. These factors are the focus to be improved in terms of cultivated land ecological security of Xinzheng City in the future.
