摘要/Abstract

摘要： 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。

Abstract: The maps of gypsum contents and forms of gypsum pedofeatures in soils of the Dzhizak Experimental Station were developed on the basis of the analysis of detailed soil survey materials. The macroand micromorphological descriptions of gypsic horizons made it possible to distinguish between three different morphotypes of these horizons. The morphological parameters of gypsic horizons were classified, and the map of their distribution was developed with the use of GIS technologies. The spatial distribution of different morphotypes of gypsic horizons showed distinct correlations with the genetic type of soils, their position in the landscape, the groundwater level, and the character of soil water regime. It was suggested that the presence of different gypsic horizons should be taken into account in the new substantivegenetic classification of Russian soils at the high taxonomic levels.

Key words: gypsic horizon, marly gypsum, powdery gypsum, incrustational gypsum, nodular gypsum
