Abstract: In order to fully reflect the sustainable development situation of cultivated land resources in Henan Province, influencing factors of sustainable utilization of cultivated land resource were explored. Based on the Pressure-State-Response model, the data of cultivated land in Henan Province from 2004 to 2013 were selected and 16 indicators were extracted to conduct a comprehensive analysis of the sustainability of cultivated land resources in Henan Province using multi-factor comprehensive evaluation method. Then linear regression model was used to forecast the sustainability in the next few years. The results showed that the pressure index had the biggest change during the 10 years. The state index and the response index showed a rising trend during the 10 years. The comprehensive utilization score of cultivated land resources in Henan Province in the 10 years was 0.6-0.8, and it was mainly affected by the pressure index and the state index. The prediction results showed that the sustainability of cultivated land resources in Henan Province would have a rising trend up to 2020, and in 2020 the comprehensive score would increase by 0.14 in comparing with that of 2013 and reach a high level of sustainable utilization.
