耕地压力评价模型的建立及应用

Foundation and Application of Evaluation Model on Cultivated Land Pressure

提出标准人均耕地面积的概念。利用标准人均耕地面积这一指标对华北平原的安阳市1995～2005年耕地压力进行分析、评价。结果表明，该市耕地压力总的趋势逐渐减轻。分析了这一指标在耕地压力评价运用中的优点和存在的不足。图3，表1，参19。

Putting forward the concept of standard farmland area per-capita, and with it, this paper analyzed and estimated the farmland pressure of Anyang in North China Plain from 1995 to 2005. The result shows that the farmland pressure generally becomes decreased. Finally, the merit and deficiency of this criterion for the appraisement of farmland pressure were discussed.
