摘 要：【目的】为国土空间农业资源的开发利用提供依据。【方法】以武汉市为例，结合《资源环境承载能力和国土空间开发适宜性评价技术指南（试行）》规范，使用ArcGIS软件先通过镶嵌、裁剪、重采样获取武汉市内部数据，对DEM高程数据执行坡度分析，生成坡度数据，使用地形坡度数据初步评定武汉市农业耕作条件并分级，根据土壤粉砂含量进行修正，再对河流、湖泊等水体区域取最低级，生成武汉市农业土地资源分级图。【结果】计算各级别农业土地资源面积可知，高等级区域面积占比9.6%，较高等级区域面积占比39.4%，中等等级区域面积占比28.8%，较低等级区域面积占比3.8%，低等级区域面积占比 18.4%，总体较适宜于农业耕作。【结论】分级成果与生态等其他数据进行综合处理后，可为国土空间农业资源的开发利用提供依据。

Abstract: [Objective] To provide a basis for the development and utilization of spatial agricultural resources in the national territory. [Method] Taking Wuhan City as an example, combined with the “Technical Guidelines for Evaluating the Carrying Capacity of Resources and Environment and the Suitability of Land and Space Development (Trial)”, ArcGIS software was used to obtain internal data of Wuhan City through embedding, cropping, and resampling. DEM elevation data was analyzed for slope, and slope data was generated. The agricultural cultivation conditions in Wuhan City were preliminarily evaluated and graded using terrain slope data, and corrections were made based on soil silt content. Then, the lowest level is selected from water bodies such as rivers and lakes to generate a classification map of agricultural land resources in Wuhan. [Result] Calculating the area of agricultural land resources at each level, it can be seen that the area of high-level areas accounts for 9.6%, the area of higher-level areas accounts for 39.4%, the area of middle-level areas accounts for 28.8%, the area of lower level areas accounts for 3.8%, and the area of low-level areas accounts for 18.4%. Overall, it is more suitable for agricultural cultivation. [Conclusion] After comprehensive processing of grading results and other ecological data, it can provide a basis for the development and utilization of spatial agricultural resources in the country.
