Changes of landscape structure and scattered greenery in the Jistebnicko region
Štěpán, Jan ; Lipský, Zdeněk (advisor) ; Romportl, Dušan (referee)
The landscape has been profoundly affected by human activity for centuries and the consequences of this interference have been growing in scale with the rising demands of modern society. The processes leading to the landscape's homogeneity, or, on the other hand, its fragmentation, have been focus of many studies which then allow us to understand how the landscape functions in its entirety and are also significant for the process of spatial planning on the local level. The aim of this theses is to assess the changes done to land cover an landscape's (micro)structure with special focus on scattered greenery (non-forest woody vegetation), as well as to examine how these changes have been mapped into the cadastral municipality of Cunkov, located in the Jistebnická vrchovina highlands, throughout the last 180 years. It is then possible to analyze these changes using the GIS and historical materials from three time periods which were beforehand selected - the years 1840, 1953 and 2019. Microstructure of the landscape plays an essential role in landscape's dynamics and for its ecologic stability.

Evaluation and charges in the extent of non-ferest woody vegetation in landscape
Demková, Katarína ; Lipský, Zdeněk (advisor) ; Chuman, Tomáš (referee) ; Skaloš, Jan (referee)
Non-forest woody vegetation is an important landscape feature of agricultural/rural landscape. Ph.D. thesis deals with evaluation of current state of non-forest woody vegetation, historical development and changes in configuration and composition in landscape. Non-forest woody vegetation was investigated in two physical-geographical different model areas (Kutnohorsko Region and White Carpathians). The thesis is based on own data collected in the field and digitized on historical aerial photos and current ortho-photos. After that, data were analyzed in relation to natural conditions and changes of landscape structure since 50s of 20th century until present. Comparing both model areas, assumed differences in character of non-forest woody vegetation, species composition, dominated type as well as relation to habitats/locations were confirmed. However, rapid changes of landscape structure in the last 60 years were caused by the same driving forces such as re-allotment, mechanization and intensification of agriculture. After 1989, processes such extensification of agriculture and land abandonment played the main role in landscape, especially in mountain regions. The second aim of the Ph.D. thesis was to identify changes in spatial configuration of non- forest woody vegetation in two...
