摘　　要：掌握云南省耕地利用的等别及其空间分布情况,对于制定适合该省耕地质量保护和土地利用决策有重大意义。以云南省129个县的农用地分等省级成果为基础,结合该省的生态环境现状分区成果,分析了全省耕地利用等别在空间上的分布特征。研究结果表明,云南省耕地利用等别范围为1—16等,平均等4.4等,总体来看,等别偏低。生态环境优区耕地利用等别范围是1—14等,平均等3.9等;良区耕地等别范围是1—16等,平均等4.8等;中区耕地等别范围是1—15等,平均等4.8等;差区耕地等别范围是1—13等,平均等4.4等;劣区耕地等别范围是1—15等,平均等3.4等。全省中、低等耕地的面积最多,集中在中区和差区,对全省耕地的平均利用等影响最大。对该研究为制定云南省耕地空间优化布局和质量提升,以及生态环境保护对策提供依据。Understanding the distribution characteristics of arable land in Yunnan Province is of great significance for making the scientific decision for using and improving the natural quality of arable land. The distribution characteris- tics of the arable land grade including 129 counties were analyzed based on the accomplishment of cultivated land clas sification in Yunnan Province. The results showed that the average natural grade was 4.4 and ranged from 1 to 16, which meant that the natural quality of arable land was relatively lower in Yunnan Province. In excellent zone, the grade ranged from 1 to 14, and the average grade was 3.9. In good zone, it ranged from 1 to 16, and the average grade was 4.8. In medium zone, it ranged from 1 to 15, and the average value was 4.8. In poor zone, it ranged from 1 to 15, and the average was 3.4. The middle and poor arable land had the largest area, and concentrated in the middle and poor zones, which had influenced the average grade the most in the whole province. This research can provide the reference for policy making about arrangement optimization, quality improvement and ecoenvironment protection for arable land in Yunnan Province.
