Soil management of large investment projects on the example of the industrial zone Kolín - Ovčáry
Bejblová, Klára ; Šefrna, Luděk (advisor) ; Kuklík, Miloslav (referee)
The thesis deal with the soil sealing and the rehanding with the uncovering of soil cultural layers. This problem is describe on the example of the industrial zone Kolín - Ovčáry. In the thesis there is the evaluation of the soil characteristics and their changes in areas where due to the trensfer of the cultural layer was created completely new structure of soil cover compact of soil units with artificial stratigraphy of profile. For this area the new classification subsumtion is suggested. The overall impacat of the soilsealig and implementation of the uncovering of soil cultural layers, despite of local incerase of soil fertility parameters, we evaluate as the degradation of soil cover.

Efficiency analysis of the protection instruments of forest and agricultural land resources
Javoříková, Zuzana ; Vejchodská, Eliška (advisor) ; Pražan, Jaroslav (referee)
Soil is an irreplaceable natural resource, a fundamental component of the environment and a source of livelihood. At present, however, urban sprawl is excessive and land cover is detrimental to the agricultural system; these are the leading contributors to soil damage and the loss of its function. The most serious type of soil degradation is "land grabbing". Such land grabbing may be considered one of the major environmental problems of the Czech Republic. Development in greenfield sites has significant environmental impacts, such as the loss of good agricultural or forest land. Unlike tools to protect forests, tools to protect agricultural land resources (ALR) appear to be ineffective. The objective of the present thesis is to explain how such tools are applied in practice, and to analyze the tools and to answer the crucial question: How do tools to protect agricultural land resources work in practice and for what reasons do tools to protect ALR appear to be ineffective? The theoretical section of the thesis provides the legislative and theoretical background. This section is primarily based on Act No. 334/1992 Sb. on the protection of agricultural land resources and Act No. 289/1995 Sb. on forests. An analysis is made and the defined issues are assessed in practice. I used qualitative research,...

Evaluation of the accuracy of built-up areas database in the Czech republic
Pohlová, Radka ; Štych, Přemysl (advisor) ; Chuman, Tomáš (referee)
The aim of this work is to give information about the European built-up area map with the high resolution which also contains the data concerning the soil sealing (Soil Sealing Layer). The main aim of this bachelor thesis is to evaluate thematic accuracy of the Soil Sealing database in the Czech Republic with the usage of the statistical methods and decision of its acceptance or rejection. This work also assesses its suitability and the next usage. At the beginning of the thesis there is a research relating to the issue of the built-up areas and statistical methods evaluating the database accuracy. There are explained the basic principles concerning the creation of SSL database and its validation which is made by the comparison of the validated database and the visually interpreted ortophotos. The evaluation of the database will be carried out by the unstratified random sample. Primarily, the statistical methods will be applied on the whole database and afterward they will compare the Czech areas divided according to the year of scanning of ortophotos from which the reference database was created. Besides the validation itself there will be a comparison of the quantitative methods followed by the evaluation of their advantages and disadvantages. Powered by TCPDF (www.tcpdf.org)

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...

Impact of urban sprawl on the environment and analysis of soil sealing along the D5 highway
Keprta, Antonín ; Chuman, Tomáš (advisor) ; Šefrna, Luděk (referee)
Sub/urbanization is one of the major factors affecting the environment. Moving population and economic activities to suburb isn't always an idyllic process, but often brings many difficulties. Impacts on the natural environment are often enormous. Degradation of air quality and water quality, soil sealing and soil degradation etc. are just some of the impacts of urban sprawl on the environment. Among others include homogenization of biota, landscape fragmentation, introduction of alien species, or light and noise pollution. Pressure on the agricultural land is made by large appropriation of land and through impervious surfaces. The study evaluates the appropriation of land along the D5 highway with areas of commercial sub/urbanization. Traffic routes through the perfect time availability are the places with the greatest concentration of commercial areas today. The study showed that new commercial areas are built on the most fertile soils. Therefore the question is whether the protection of soils in the Czech Republic is sufficient. Unfinished and often missing plans of territory make often the situation even worse. Keywords: sub/urbanization, urban sprawl, pollution, soil sealing, soil protection
