Abstract
Objective – to investigate main trends of development and direction of changes in the structure of landscape compositions of Dendropark Trostjanets during 2005–2015.
Material and methods. 230 landscape compositions were the objects of this investigation. They were represented by mixed (coniferous with desidous plants) and monotypical (single species) ornamental groups. The structural changes of compositions were determined comparing the number of taxa and plants (individuals) and their decorative characteristics in 2005 and 2015.
Results. The changes in the composition structure are divided into three categories: dynamic, which occur as a result of the process of growth and development of plants without changes in the composition of the species; transformation changes – partial changes in the taxonomic composition, that can be resulted in a transformation of one composite type into another one; degradation changes – a complete change of the primary taxonomic composition. It was found that the vast majority of the studied compositions were underwent a different degree of transformational changes. The smallest number of compositions is subject to degradation changes, which make the primary taxonomic composition has completely changed. The intermediate place is occupied by compositions that did not lose the primary species composition during the studied period and met with only dynamic changes.
Conclusion. The analysis of changes in the composition structure makes it possible to identify the decorative groups that require of priority intervention for their optimization and systematic implementation of measures focused on improving of the decorative appearance of park compositions.
