在分析详细土壤调查资料的基础上,制作了Dzhizak试验站区各种土壤的石膏含量和石膏土壤形貌的形态分布图。石膏层宏、微形态描述使区分这些石膏层的三种不同形态类型成为可能。并对石膏层的形态参数进行了分类,采用GIS技术制做了这些形态参数的分布图。空间分布显示,石膏层不同形态类型与土壤发生类型、其在景观中的位置、地下水位以及土壤水分情势有明显的相关性。因此,建议在土壤系统分类高等级上,俄罗斯土壤的新实质发生分类中应考虑不同石膏层的出现。
Based on the analysis of detailed soil survey data, the gypsum content of various soils in the Dzhizak test station area and the morphological distribution of the gypsum soil topography were produced. Gypsum Macro, Micromorphological Descriptions make it possible to distinguish between three different morphological types of these gypsum layers. And gypsum layer morphological parameters were classified, using GIS technology to make the distribution of these morphological parameters. Spatial distribution shows that there are significant correlations between the different types of gypsum layers and soil types, their position in the landscape, groundwater level and soil moisture. Therefore, it is suggested that the appearance of different gypsum layers should be considered in the classification of the new substance of soil in Russia at a high level of soil system classification.
