| 摘 要： | 随着城镇化的逐步推进，农村耕地正在减少，进一步合理利用耕地和预测耕地的变化情况正是我们面临的问题。本文在某市人均耕地现状的基础上，用最小人均耕地面积和实际人均耕地面积的比值对某市耕地压力状况进行了分析，并运用回归摸型预测耕地压力的变化趋势，为缓解耕地压力，合理利用耕地资源提供依据。

| Abstract: | With the gradual of urbanization, rural land is decreasing,and how to use the land rationally and predict the tendency of land using correctly is the problem we face. This paper analyses the change of cultivated land pressure from 1949 to 2004, and chooses the mathematical model to prediet the trend of cultivated land pressure index in the future. It provides a basis for making rational use of cultivated land and offering the protection of cultivated land. |

| Keywords: | minimum area per capita of cultivated land index of cultivated land pressure dynamic analysis |
