Acer Genus In Urban Parks On The Example Of Wroclaw City In Poland And Changsha City In China

This a graduate dissertation of the student of the Wroclaw University of Environmental and Life Sciences and Hunan Agricultural University about the way of using species within Acer genus in Wroclaw in Poland and Changsha City in China. The thesis presents differences and similarities between two cities that lie more than eight thousand kilometers away from each other. The massive gap between them is not ony geographic but also include history, climate, cultural heritage and a lots of other factors. This paper introduce the subject by presenting climatic conditions in Wroclaw and Changsha as factors having a significant impact on the dendroflora in comparing cities. The next chapter presents informations about the Acer genus, then shows an overview of the native and the most common species in both countries, describing their morphology, use, cultural significance, distribution etc. The following chapter briefly presents the checked objects-their location, size and features. It is very difficult to compare places as varied as the 700 thousand people, a city in medium-sized country in Europe and more than 10-million metropolis in a country with several billion people in south-east Asia, where often one street is longer than whole Wroclaw, so, in some places, the lack of analogy can be surprising (eg. the choice of species described in detail or selection of the checked places). These choices, however, are considered and taken in the way to show as good as possible the contrasts, similarities, peculiarities and characteristics of both cities. The most common species in Poland was native to the country A. platanoides and introduced for China A. palmatum.
