Abstract

The aim of the research is to analyze the factors of development, distribution and landscape differentiation of geological and geomorphological processes in the subalpine and alpine highlands of Chornohora, as well as to determine the influence of geological structure and morphometric features on the intensity of their development. The methodological basis of the study is a combination of methods of field research and geoinformation analysis using GIS, which allowed to identify the main centers of the highlands of Chornohora of rockfalls, screes, landslides and linear erosion. On the basis of the landscape approach the spatial differentiation of geological and geomorphological processes in high altitude terrains and landscape structures is analyzed and their complex analysis is carried out, and with the help of geoinformation and statistical data processing on location and number of cells the intensity of negative processes is calculated. The main result of the study is a map of the distribution of negative geological and geomorphological processes (rockfalls, screes, landslides and linear erosion) in the landscape complexes of the subalpine and alpine highlands of Chornohora, as well as a map of a key area near Smotrych Mountain, which expresses landscape processes at the level of landscape striyas and tracts. As a result of the research the structure and specifics of development of geological-geomorphological processes in geocomplexes of different origin and with different morphological and morphometric parameters are analyzed. The influence of geological structure on the development of processes is manifested in the dominance of massive sandstones and sandstone flysch, which contributed to the development of large and steep landforms with inherent intense rockfalls, screes and linear erosion. The analysis of the intensity of the manifestation of these processes testifies to their greatest development in the geocomplexes of ancient-glacial-exarational genesis – corries, cirques, glacial troughs, nival niches, etc. The development, nature and intensity of the manifestation of negative geological and geomorphological processes in landscape complexes of nival erosion and denudation genesis differ significantly. The peculiarity of the differentiation of processes here is their clear dependence on the composition and peculiarities of the occurrence of bedrock stratum, relief morphometry and so on. An important result of the study is the above-mentioned map of the highlands in the vicinity of Smotrych Mountain, which expresses the previously little-studied landslides to the narrow bands of argillites and argillite flysch. Originality. The relationship between the diversity and distribution of negative geological and geomorphological processes with the genesis of landscape complexes of the Chornohora highlands, their structure, structural-lithological and morphometric features is determined. Landscape differentiation and intensity of rockfalls, screes, landslides and linear erosion in the highlands of the studied massif are analyzed and described. Practical significance. The results of the study contribute to the further study of the dynamics and properties of highlands landscape complexes of Chornohora, as well as provide an opportunity to predict the peculiarities of the geological situation and optimize the nature management system, in particular - organizational features of recreational and tourist activities.

本研究的目的是分析Chornohora亚高山和高山高地地质地貌过程的发展、分布和景观分化因素,并确定地质结构和地貌特征对其发展强度的影响。该研究的方法论基础是结合了实地研究和地理信息系统的地理信息分析方法,从而确定了Chornohora高地的落石、碎石、滑坡和线性侵蚀的主要中心。在景观方法的基础上,分析了高海拔地形和景观结构中地质地貌过程的空间分异,并对其进行了复杂分析,并借助地理信息和对单元位置和数量的统计数据处理,计算了负过程的强度。该研究的主要结果是绘制了Chornohora亚高山和高山高地景观综合体中负面地质和地貌过程(落石、碎石、滑坡和线性侵蚀)的分布图,以及Smotrych山附近一个关键区域的地图,该地图在景观区和地块层面上表达了景观过程。作为研究的结果,分析了不同起源、不同形态和形态参数的地质复合体中地质地貌过程的结构和发展细节。地质结构对过程发展的影响表现为块状砂岩和砂岩复理石占主导地位,这有助于形成具有强烈落石、碎石和线性侵蚀的大型陡峭地貌。对这些过程表现强度的分析证明,它们在古代冰川异常成因的地质复合体中得到了最大的发展——洞穴、冰斗、冰川槽、雪位等,冰川侵蚀和剥蚀成因景观复合体中负地质地貌过程的表现性质和强度存在显著差异。这里的过程分化的特点是明显依赖于基岩地层的组成和产状特点、地形地貌测量等。研究的一个重要结果是上述斯莫特里奇山附近高地的地图,它将以前很少研究的滑坡表示为泥质岩和泥质岩复理石的窄带。独创性确定了Chornohora高地负地质地貌过程的多样性和分布与景观综合体的成因、结构、构造岩性和形态特征之间的关系。分析和描述了研究地块高地落石、碎石、滑坡和线性侵蚀的景观分化和强度。实际意义。研究结果有助于进一步研究Chornohora高地景观综合体的动态和特性,并为预测地质情况的特点和优化自然管理系统,特别是娱乐和旅游活动的组织特征提供了机会。
