Abstract

Throughout the history of soil science development, one of the most controversial issues was the explanation of the genesis of the profile textural-differentiated soils influenced by forest vegetation and climate conditions within the Cis-Carpathian region, Ukraine. Scientists' views on the formation of the eluvial-illuvial, namely granulometric content, and profile differentiation have been and remain ambiguous due to the contradictory criteria of diagnosing the processes of eluvial soil degradation (lessivage, podzolization, eluvial-gleying process) and the almost similar results of these processes. The complexity and ambiguous interpretation of the genetic nature of the profile textural-differentiated soils of the Cis-Carpathian region necessitates the development of clear diagnostic criteria for revealing their genetic nature. The purpose of the work is to establish the diagnostic criteria of elementary soil-forming processes in profile textural-differentiated forest soils of the Cis-Carpathian region based on the analysis of data on soil properties previously collected by the authors. It has been established that in sod-podzolic soils formed under forest, the main profile-forming elementary process of soil formation is podzolization, which is characterized by the negative values of the eluvial-accumulative coefficients and the coefficient of change of the silicate part for the upper three horizons. The processes of lessivage and segregation are of little intensity in this type of soils. The main profile-forming elementary processes of soil formation in brown-podzolic soils (Neocambic Gleyic Retisols) are lessivage and inner soil argillization with little podzolization, the eluvial-gleying process and segregation effects. Keywords: forest soils, argillanes, neoplasms, ortsteins, podsolization, elementary soil-forming processes, Cis-Carpathian region

乌克兰Cis-Carpathian地区森林土壤剖面纹理分化的成土过程

在整个土壤科学发展史上，最具争议的问题之一是解释乌克兰喀尔巴阡山脉地区受森林植被和气候条件影响的剖面结构分化土壤的起源。由于诊断残积土壤退化过程（变稀、灰化、残积潜育过程）的标准相互矛盾，以及这些过程几乎相似的结果，科学家们对残积洪积的形成，即粒度含量和剖面分化的看法一直是模糊的。Cis Carpathian地区剖面结构分化土壤遗传性质的复杂性和模糊解释需要制定明确的诊断标准来揭示其遗传性质。本工作的目的是在分析作者先前收集的土壤特性数据的基础上，建立喀尔巴阡山脉地区剖面结构差异森林土壤基本土壤形成过程的诊断标准。研究表明，在森林下形成的草皮灰化土中，土壤形成的主要剖面形成基本过程是灰化，其特征是上三层的残积累积系数和硅酸盐部分的变化系数为负值。在这种类型的土壤中，减少和分离的过程强度很小。棕色灰化土（新形成层Gleyic Retisols）土壤形成的主要剖面形成基本过程是少泥化和少量灰化的内部土壤泥化、残积潜育过程和分离作用。关键词：森林土壤，粘土，肿瘤，ortsteins，足泥化，基本土壤形成过程，西喀尔巴阡地区

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
