Материал Classification and mapping of landscape of Truong Sa Islands, Vietnam at the scale of 1:250 000(2022) Nguyen, Dang Hoi; Ngo, Trung Dung; Nguyen, Quoc Khanh; Nguyen, Cao Huan; Phan, Dong Pha; Vu, Le PhuongMarine landscapes study is a new direction of modern geography, formed and developed in Western countries and Russia and other countries. In Vietnam, research on marine landscapes is still very limited. On the basis of clarifying the concept, applying remote sensing — GIS and complex field methods, a classification system has been established and a landscape map of the Truong Sa Islands has been drawn at a scale of 1:250 000. The study area includes 1 system, 1 sub-system, 4 classes, 7 sub-classes and 20 landscape types. The highest diversity is the marine landscapes, with 3 classes, 6 sub-classes and 19 landscape types. The island landscape class only includes 1 landscape type of tropical island vegetation. The offshore shallow marine landscape class (0–200m) covers a small area but is differentiated, consisting of 2 classes (50 % of the total classes) and 9 types (45 % of the total types). The landscape of tropical islands is strongly changed in both solid vegetation cover and hydrological regime, in which many entities have soil cover, and a mixed vegetation of both continental and island flora. The landscape of the offshore shallow sea, especially 100 m uppermost layer, is mainly composed of corals and other reef organism groups. The landscape structures of the Truong Sa Islands represent not only the characteristics of their constituent components but also the dynamics of the landscape, especially in the marine domain.Материал Transformation and ecological succession of natural–anthropogenic landscapes in Konkakinh–Konchurang conservation territory, Vietnam(2019) Nguyen, Dang Hoi; Ngo, Trung Dung; Dang, Hung Cuong; Kolesnikov, S. I.; Tishkov, А. А.Study about characteristics of diversity, change and ecological succession of landscapes is an important content in determining territorial division, especially in the monsoon tropics such as the Central Highlands of Vietnam, where the strong division of non-zonal rule. Konkakinh–Konchurang conservation territory is a special geographic site located in the north eastern part of Gia Lai province, which is noticeable for a profound division of components, natural and human factors. The humid tropical climate of this area is simultaneously influenced by the climate of the Central Highlands and the Central Coast. Both the diversified natural conditions and the strong impact of residents have contributed to the creation of the typical natural-anthropogenic landscape system in this studied area. Natural–anthropogenic landscapes are quite differentiated from one system, one subsystem, three classes, five subclasses, 13 types and 87 kinds. The diversity in the landscape structure is evident in the elevation law through subclasses. Landscape diversity is reflected through not only the number of landscapes, but also the frequency of any certain landscape in the studied territory. During the research period from 2005 to 2017, significant changes in landscape of this studied area, in both quantitative and qualitative manners, were observed. During approximately 13 years, the landscape of this area has greatly changed. In 2005, there was a total of 94 kinds of landscape, with the domination of the group of evergreen broadleaf tropical forest types with shrubs, grasslands, industrial crops and annual crops dominate. The comparison between these two periods shows that there are 43 landscape kinds completely disappeared and 33 new landscape kinds formed. The remaining landscapes have fluctuations in area. In this studied area, the formation of typical landscape succession chains reflects living activities of local human. The evergreen broadleaf forest landscape under mankind impact has resulted in a dramatic change. The succession chains change over different short periods of time, leading to the creation of new landscapes.
