摘　　要：本文主要应用农用地分等定级技术选取适合云南省的评价指标,采用定量与定性结合的方法得出农业耕作条件下的土地资源评价等级。再参考资源环境承载能力和国土空间开发适宜性评价方法指南,应用arcgis10.2得出结果。结果表明:城镇建设功能的土地资源评价中低等级分布最多,占整个云南省土地面积的69.24%,较低、中等、较高、高等级区域分别占13.53%,7.53%,5.45%,4.25%;农业耕作条件下的土地资源评价等级中,低、较低、中等、较高、高等级分别占整个云南省土地面积的5.60%,32.10%,29.68%,22.89%,9.73%,其中较低等级分布最多。前者低等级区域主要分布在云南省的西北部,高等级区域主要分布在云南省东部;后者低等级区域主要分布在云南省的西北部,高等级区域主要分布在云南省东部、西部、西南、东北部。This paper mainly uses agricultural land grading and grading technology to select evaluation indicators suitable for Yunnan Province, and uses quantitative and qualitative methods to obtain the land resource evaluation grade under agricultural cultivation conditions. Then refer to the resource and environment carrying capacity and the guidelines for the appraisal method of land space development suitability, and use arcgis 10.2 to get the results. The results show that: the land resource evaluation of urban construction function has the most low-level distribution, accounting for 69.24% of the total land area of Yunnan Province, and the lower, medium, higher, and high-level areas account for 13.53%, 7.53%, 5.45%, and 4.25% respectively;Among the land resource evaluation grades under agricultural cultivation conditions, low, low, medium, high, and high grades account for 5.60%, 32.10%, 29.68%, 22.89%, 9.73% of the total land area of Yunnan Province respectively, of which the lower The most level distribution. The former low-level areas are mainly distributed in the northwest of Yunnan Province, the high-level areas are mainly distributed in the east of Yunnan Province;the latter low-level areas are mainly distributed in the northwest of Yunnan Province, and the high-level areas are mainly distributed in the east, west and southwest of Yunnan, northeast.
