| 摘要: |
| 文章以北京市大兴区为例，研究耕地质量等级监测中的县域土地利用系数更新方法;以农用地分 等成果为本底数据，兼用调查与统计数据，重新评定最大标准粮单产，以逐级修正法更新综合土地利用系 数。结果表明:综合土地利用系数更新结果整体趋势升高，数据变化平稳，平均值与统计数据计算结果基 本一致。结论:在农用地分等成果准确可靠的前提下，运用逐级修正法对县域土地利用系数进行更新，过 程快速便捷，结果科学合理，适用于耕地质量等级监测工作。 |

| Abstract: |
| Taking Daxing District of Beijing as an example， the purpose of this study is to study the updating meth- od of comprehensive land utilization coefficient in arable land monitoring. Based on the classification agricultural land grade data and combined with the investigation and statistical data， this paper reevaluated the highest standard food yield and modified the comprehensive land utilization coefficient. The results showed that the holistic trend of comprehensive land utilization coefficient increased， and the average value was basically same to the statistic data. The conclusion was that in the condition that the classification results of agricultural land grade was accurate and re- liable; updating the comprehensive land utilization coefficient using the method of modifying by degrees was fast and convenient. The method was appropriate for monitoring quality level of arable land. |
| Key words: land management quality of arable land monitoring comprehensive land utilization coefficient modi- fying by degrees the highest standard food yield |
