Abstract A landscape stability assessment is made for the major islands of the Empress Eugénie Archipelago. The landscapes are ranked according to groups of stability on the basis of an integrated numerical score for 17 indicators. It was found that the islands are dominated by landscapes of moderate stability, and by unstable landscapes. The islands are characterized by a significant differentiation with respect to the areas of landscapes belonging in different groups of stability. This is due to the individual features in the landscape organization of the insular geosystems, and to the degree of their economic transformation. Results of cartographic and correlation analyses showed that a considerable contribution to the integrated indicator of landscape stability is made by the geomorphological structure of the territory, and by vegetation cover. However, correlation analysis did not reveal any unambiguous relationship with the other landscape components. This is accounted for by the natural factor (low-mountain relief) and a severe anthropogenic transformation of vegetation, leading to an attenuation of the relationship of the structure of vegetation cover with the other landscape components. A statistical investigation using principal component analysis (PCA) showed the role of the landscape components in the formation of the integrated indicator of stability of insular geosystems. The largest load is experienced by the geomorphological structure, followed by soil and vegetation cover. An individual analysis of island landscape stability by PCA revealed a variation in the loads on the indicators of landscape stability in principal components, which is due to the rate and direction of response of the insular geosystems on homogeneous factors. It is concluded that each insular geosystem has individual characteristics of the formation of an integral landscape matter-energy system, with an inherent set of self-regulation and selforganization mechanisms which arise in accordance with the area of land, physical-geographical conditions and the degree of anthropogenic pressure. Planning of a further development of the insular territories should take into consideration the individual characteristics of the functioning of landscapes and the role of their components in the formation of the integrated stability indicator.

欧仁妮皇后群岛（彼得大帝湾，日本海）岛屿地质系统的稳定性评估

摘要 对欧仁妮皇后群岛的主要岛屿进行了景观稳定性评估。景观根据 17 项指标的综合数值得分，根据稳定性分组进行排名。发现这些岛屿以中等稳定性景观和不稳定景观为主。这些岛屿的特点是在属于不同稳定组的景观区域方面存在显着差异。这是由于岛屿地质系统景观组织的个别特征，以及它们的经济转型程度。制图和相关性分析的结果表明，领土的地貌结构和植被覆盖对景观稳定性的综合指标做出了相当大的贡献。然而，相关性分析并未揭示与其他景观成分的任何明确关系。这是由自然因素（低山地势）和严重的人为植被改造造成的，导致植被覆盖结构与其他景观成分的关系减弱。使用主成分分析 (PCA) 进行的统计调查显示了景观成分在形成岛屿地质系统稳定性综合指标中的作用。地貌结构承受的负荷最大，其次是土壤和植被覆盖。PCA 对岛屿景观稳定性的个别分析揭示了主成分中景观稳定性指标的负载变化，这是由于岛屿地质系统对均质因素的响应速度和方向。得出的结论是，每个岛屿地质系统都具有形成完整景观物质-能量系统的独特特征，具有一套固有的自调节和自组织机制，这些机制根据土地面积、自然地理条件和程度而产生。人为压力。岛屿领土进一步发展的规划应考虑到景观功能的个别特征及其组成部分在综合稳定性指标形成中的作用。得出的结论是，每个岛屿地质系统都具有形成完整景观物质-能量系统的独特特征，具有一套固有的自调节和自组织机制，这些机制根据土地面积、自然地理条件和程度而产生。人为压力。岛屿领土进一步发展的规划应考虑到景观功能的个别特征及其组成部分在综合稳定性指标形成中的作用。得出的结论是，每个岛屿地质系统都具有形成完整景观物质-能量系统的独特特征，具有一套固有的自调节和自组织机制，这些机制根据土地面积、自然地理条件和程度而产生。人为压力。岛屿领土进一步发展的规划应考虑到景观功能的个别特征及其组成部分在综合稳定性指标形成中的作用。
