The water erosion research was carried out in the lowland type of hilly landscape. The aim was to monitor and evaluate the importance of environmental factors (steepness of slope, relief shapes, aspect, slope length, combination slope length (L) and slope (S)—LS factor, types of land use changes) for the development of water erosion. We focused on the identification of areas threatened by erosion by interpreting aerial photographs from several time periods. This was followed by verification of erosion using soil probes. We identified 408.44 ha of areas affected by erosion, and measured the depth of soil and “A” horizons thickness. The environmental factors were modeled in geographical information systems by tools for spatially oriented data. Subsequently, the influence and significance of individual environmental factors were compared, and the probability of erosion was statistically estimated. The decisive factors in the formation of erosive surfaces are the LS factor and the slope. We also consider the factor of the relief shape to be important. The shape did not appear to be very significant as a separately evaluated factor, but all convex parts correlate with the identified erosion surfaces. The susceptibility of erosion related to the aspect of the slopes to the cardinal directions has not been confirmed. Types of land use changes with the most significant relation of erosion were confirmed in areas of strong intensification. We confirmed the importance of factors and land use for the development of erosion processes.

环境因素对农业用地土壤水蚀发展的重要性:斯洛伐克 Hronská Pahorkatina Hill Land 的南部

水蚀研究是在低地类型的丘陵景观中进行的。目的是监测和评估环境因素(斜坡陡度、起伏形状、坡向、斜坡长度、组合斜坡长度 (L) 和斜坡 (S) — LS 因子、土地利用变化类型)对发展的重要性。水侵蚀。我们通过解释几个时间段的航空照片,专注于识别受侵蚀威胁的区域。随后使用土壤探针验证侵蚀。我们确定了 408.44 公顷受侵蚀影响的区域,并测量了土壤深度和“A”层厚度。环境因素通过面向空间的数据工具在地理信息系统中建模。随后,比较了个体环境因素的影响和意义,并对侵蚀概率进行统计估计。形成侵蚀面的决定性因素是 LS 因子和坡度。我们还认为浮雕形状的因素很重要。作为单独评估的因素,形状似乎不是很重要,但所有凸出部分都与识别的侵蚀表面相关。与斜坡相对于基本方向的角度有关的侵蚀敏感性尚未得到证实。与侵蚀关系最显着的土地利用变化类型在强集约化地区得到确认。我们确认了因素和土地利用对侵蚀过程发展的重要性。我们还认为浮雕形状的因素很重要。作为单独评估的因素,形状似乎不是很重要,但所有凸出部分都与识别的侵蚀表面相关。与斜坡相对于基本方向的角度有关的侵蚀敏感性尚未得到证实。与侵蚀关系最显着的土地利用变化类型在强集约化地区得到确认。我们确认了因素和土地利用对侵蚀过程发展的重要性。我们还认为浮雕形状的因素很重要。作为单独评估的因素,形状似乎不是很重要,但所有凸出部分都与识别的侵蚀表面相关。与斜坡相对于基本方向的角度有关的侵蚀敏感性尚未得到证实。与侵蚀关系最显着的土地利用变化类型在强集约化地区得到确认。我们确认了因素和土地利用对侵蚀过程发展的重要性。与斜坡相对于基本方向的角度有关的侵蚀敏感性尚未得到证实。与侵蚀关系最显着的土地利用变化类型在强集约化地区得到确认。我们确认了因素和土地利用对侵蚀过程发展的重要性。与斜坡相对于基本方向的角度有关的侵蚀敏感性尚未得到证实。与侵蚀关系最显着的土地利用变化类型在强集约化地区得到确认。我们确认了因素和土地利用对侵蚀过程发展的重要性。
