摘　　要：农用地"等"是全国尺度内农用地自然质量差异的评价,"级"是区域尺度内的评价。对如何充分利用GIS技术和省级尺度农用地"等"的成果进行县域内农用地"级"的划分进行了探讨,并以平阴县为实例建立了县域内定级修正指标体系,定级结果符合平阴县实际。实例证明,该县域内农用地定级方法是科学合理高效的,而且GIS技术的应用大大提高了定级的效率,可为县域内农用地定级提供参考。Agricultural land class is the evaluation of natural quality differences of agricultural land in the national scale,while grade is the evaluation in regional scale.This study has researched how to complete the agricultural land grading in county scale under the support of GIS and agricultural land classification production of province scale.What is more,taking Pingyin county as the example,we have established the grading modification index system in county scale.And the grading result is in concordance with the reality.It is proved that this method for agricultural land grading is scientific and efficient.Meanwhile,the application of GIS in the procedure has improved the grading efficiency.This study can provide reference for agricultural land grading in county scale.
