摘要： 为了提高新郑市土地资源利用水平，采用机制法的逐步订正模型对新郑市的耕地生产潜力进行定量估算；用耕地生产力指数模型中的PI指数作土壤修正系数对气候生产潜力做修正；用生产潜力指数，对耕地生产力水平进行评价。结果表明：新郑市的平均土壤修正系数为0.54；平均生产潜力为19393.84 kg/hm2；平均生产潜力指数为47.39%，因此新郑市尚有较大的耕地生产潜力有待开发。

Abstract: In order to improve utilization of land resources in Xinzheng City, the paper used gradual reduction model of the mechanism method to quantitatively estimate the production potential of land resources of Xinzheng City and to modify climate productive potential with the PI index of land productivity index model for soil correction coefficient, and used production potential index to evaluate arable land productivity level. The results showed that, soil correction coefficient of all towns in Xinzheng City reached an average of 0.54, arable land potential productivity reached an average of 19393.84 kg/hm2, and production potential indexes reached an average of 47.39%, so there is still considerable land production potential to be exploited.
