| 摘要: |
| 该文以退耕还林试点市延安为研究对象，运用最小人均耕地面积和耕地压力指数模型法，对延安 市1997～2009年间耕地变化动态与粮食生产情况进行了分析研究。研究结果表明:1998～2003年延安市耕 地压力指数、最小耕地面积呈上升态势，2003年后则趋于下降;近些年耕地压力指数略高于1，区内耕地 压力、粮食供需矛盾有所缓解，但粮食安全问题依然存在。 |

| Abstract: |
| Taking Yan'an city， a pilot city of grain for green project， as the study object， this paper analyzed the change in arable land and crop productivity from 1997 to 2009 using the minimum cropland average per capita and cropland pressure index model. The results indicated that the cropland pressure index and the minimum cropland area showed an increase trend from 1998 to 2003， but a decline since 2003. In recent years， the cropland pressure index is little higher than The pressure of cropland area and the imbalance between grain supply and demand had been eased， but the grain security problem still existed. |
