Abstract—

A new method of digital mapping of the soil cover pattern with calculation of the share of soils of different taxa and degree classes for soil erosion in the soil associations is proposed. A comparative analysis of soil maps obtained using different methods of construction (visual expert and digital) and with their different contents (displaying the dominant soil or soil associations) has been performed. In the case of mapping by the visual expert method (with the display of the dominant soil), a significant underestimation of the total area of moderately and strongly eroded soils in comparison with the digital mapping is noted. These differences are due to the underestimation of the area of small polygons with moderately and strongly eroded soils in the composition of soil associations on slopes of low steepness and in shallow hollows in the visual expert method of mapping. When the content of digital maps is generalized from soil associations to dominant soil categories, a significant change in information on the degree of soil degradation by erosion is also noted. Comparison of visual expert and digital methods for mapping soils of different taxa indicates a high degree of compliance between the spatial location and area of soil delineations with similar component content in both cases. The greatest differences between the soil maps created by these methods are noted for the soils with periodic overmoistening, namely, meadow-chernozemic (Luvic Chernic Phaeozem (Oxyaquic)) and chernozemic-meadow (Luvic Stagnic Chernic Phaeozem) soils because of the poor consideration for microtopography in traditional mapping. In general, it can be concluded that the creation of a digital map is more difficult in terms of the need to use specialized computer programs and mathematical models. However, the resulting digital databases contain information of a higher level of detail than traditional soil maps.

土壤协会和侵蚀土壤的数字制图（别尔哥罗德州Prokhorovskii区）

摘要-

提出了一种新的数字化土壤覆盖格局测绘方法，通过计算土壤分类中不同分类单元和土壤侵蚀程度等级的土壤份额。对使用不同的构造方法（可视化专家和数字方式）及其内容（显示主要土壤或土壤关联）获得的土壤图进行了比较分析。在通过视觉专家方法制图（显示主要土壤）的情况下，与数字制图相比，注意到严重侵蚀土壤的总面积明显低估了。这些差异是由于在视觉专家制图方法中低坡度和浅空洞的土壤组合组成中低估了中度和强侵蚀土壤的小多边形的面积。当数字地图的内容从土壤协会到主要土壤类别被概括时，关于土壤因侵蚀而退化的程度的信息也将发生重大变化。视觉专家和数字方法对不同分类单元的土壤作图的比较表明，在两种情况下，土壤轮廓的空间位置和面积在成分相似的情况下都具有高度的一致性。这些方法创建的土壤图之间最大的差异是对于周期性过湿的土壤，即 草甸黑钙土（Luvic Chernic Phaeozem（Oxyaquic））和黑钙土（Luvic Stagnic Chernic Phaeozem）土壤是因为传统制图中对微地形的考虑不多。通常，可以得出结论，就使用专用计算机程序和数学模型的需求而言，创建数字地图更加困难。但是，生成的数字数据库包含的信息比传统的土壤地图要高。
