Abstract
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.
