Spatial development of soil sealing in Prague suburban fringe from 19th century till present.
Stachura, Jan ; Šefrna, Luděk (advisor) ; Chuman, Tomáš (referee)
Built up areas are dynymically evolving component of suburban landscape. Prague periphery is the area, where this evolution is fastest. This can be a problem because the very fertile soils are located in Prague fringe. Their loss is therefore connected with the law protection of agricultural soils. A set of 22 cadasters around the Prague made the area of interest of this master thesis. They were defined to cover the variability of geological substrate, climate, relief and soils and also some socioeconomic parametres (distance form highway and from Prague centre). I used a several data about built up areas to explain the trends in set: Stable cadaster, Third military mapping, aerial photos from 1950s and present orthophoto. The development of built up areas in the final set was assesed by a several parametres which contain the total area, structure, fertility of sealed land and diversity of soils. Problem of determining soil diversity was one of the goals of master thesis. Taxonomical dendrogram of soils with including taxonomical differences is the output of this part. Main trend of development were assesed by using multidimensional statistic method: classical scaling and hierarchical clustering. Results confirmed that more fertile soil are built up nowadays than in the past and also diversity of...
