Land classification assists in identifying optimal crop selection for a given field, and land use capability gives an indication of potential agronomic productivity. However, these approaches are most germane to farming systems managed with high technology. This study sought to adapt land use capability to farming systems managed with low and intermediate levels of technology. Assessment of the classification criteria was conducted using erosion data as a primary indicator. The adapted (and currently in effect) criteria were compared in three regions in Minas Gerais, Brazil, each one representing one of the management levels. Erosion often results from inappropriate practices in land use or management. Therefore, maps of adequacy of land use and management were used to measure how well each one corresponded to the erosion map. The adapted criteria changed the spatial distribution of the classes of land use capability in different ways. Correspondence between the land use/management map and the erosion map increased from 71% to 88.5% when the criteria adapted to an intermediate level of management were used. It also increased from 62.9% to 66.7% when the criteria adapted to a low level of management were considered, better reflecting current erosion. Therefore, adopting adapted classification criteria is recommended for planning land use in locations where farming systems with low and intermediate levels of management are common, requiring re‐adaptation and reassessment depending on socio‐environmental factors.

中低等技术耕作制度中土地利用能力分类适应：土壤侵蚀指标

土地分类有助于确定给定田地的最佳农作物选择，土地利用能力可提供潜在农艺生产力的指标。但是，这些方法与采用高科技管理的耕作系统最相关。这项研究试图使土地利用能力适应采用中低水平技术管理的耕作制度。使用侵蚀数据作为主要指标对分类标准进行评估。在巴西米纳斯吉拉斯州的三个地区，对经过调整（目前有效）的标准进行了比较，每个地区代表一种管理水平。侵蚀通常是由于土地使用或管理不当造成的。因此，用土地利用和管理的充分性图来衡量每个人与侵蚀图的对应程度。适应标准以不同方式改变了土地利用能力类别的空间分布。当使用适合中级管理水平的标准时，土地使用/管理图与侵蚀图之间的对应关系从71％增加到88.5％。当考虑到适应于低水平管理的标准时，它也从62.9％增加到66.7％，更好地反映了当前的侵蚀。因此，建议在管理水平较低和中等的农业系统普遍的地区规划土地使用时采用适应性的分类标准，这需要根据社会环境因素进行重新适应和重新评估。当使用适合中级管理水平的标准时，土地使用/管理图与侵蚀图之间的对应关系从71％增加到88.5％。当考虑到适应于低水平管理的标准时，它也从62.9％增加到66.7％，更好地反映了当前的侵蚀。因此，建议在管理水平较低和中等的农业系统普遍的地区规划土地使用时采用适应性的分类标准，这需要根据社会环境因素进行重新适应和重新评估。当使用适合中级管理水平的标准时，土地使用/管理图与侵蚀图之间的对应关系从71％增加到88.5％。当考虑到适应低水平管理的标准时，也从62.9％增加到66.7％，更好地反映了当前的侵蚀。因此，建议在管理水平较低和中等的农业系统普遍的地区规划土地使用时采用适应性的分类标准，这需要根据社会环境因素进行重新适应和重新评估。
