Landscape metrics play an important role in pedodiversity studies. Despite considerable research on pedodiversity, there is a lack of standardised methods for assessing the degree of soil cover diversity, especially in the urban area. Hence, in this work, we propose a new approach for spatial analyses of the urban soils using landscape metrics. The aim of the study was to develop a qualitative–quantitative landscape‐metrics‐based method for the pedodiversity measurement and the degree of soils' transformation. The research included: selection of input data (cartographic materials), data digitisation, development of an urban soil map and a soil transformation map, creation of a hexagonal grid within the city's administrative boundaries, calculation of eight landscape metrics and their statistical selection, and finally, development of the maps based on original pedodiversity index. Despite the homogeneous initial soil cover of the city, the present, human‐transformed soil cover is relatively heterogeneous by urban soil complexes and the degree of soil transformation. The developed method allows areas of greatest landscape fragmentation to be identified, and thereby to precisely indicate the areas of the most strongly human‐transformed soils and fertile soil losses, which can support urban spatial planning and landscape design.

景观指标作为分析城市差异性的工具

景观指标在基础性研究中起着重要作用。尽管有很多关于土壤多样性的研究,但是缺乏评估土壤覆盖多样性程度的标准化方法,特别是在城市地区。因此,在这项工作中,我们提出了一种使用景观指标对城市土壤进行空间分析的新方法。该研究的目的是开发一种定性,定量的景观度量方法,用于测量土壤的坡度和土壤转化的程度。该研究包括:选择输入数据(制图材料),数据数字化,开发城市土壤图和土壤转化图,在城市行政区域内创建六边形网格,计算八个景观度量及其统计选择,以及最后,基于原始指数的地图开发。尽管城市的初始土壤覆盖率是均匀的,但由于城市土壤复合体和土壤转化程度的不同,目前由人为转化的土壤覆盖率相对而言是异质的。所开发的方法可以识别出最大的景观破碎化区域,从而精确地指示出人类转化最强烈的土壤和肥沃的土壤流失的区域,从而可以支持城市空间规划和景观设计。
