Environmental modelling of landuse changes in the neighbourhood of coal mines with the GIS
Antalová, Daniela ; Matějíček, Luboš (advisor) ; Kopačková, Veronika (referee)
ENVIRONMENTAL MODELLING OF LAND USE CHANGES IN THE NEIGHBOURHOOD OF COAL MINES WITH THE GIS Abstract Human society causes an increasing pressure on land and its use. The requirements and demands of humanity has significantly changed in the last few decades. This is the foundation of continuous environmental impacts, particularly in those areas where mining companies exploit natural resources on a large scale for personal and economic well-being, and thus significantly transform the land surface. The objective of this thesis is to refer to changes in land use in the vicinity of surface coal mines in the districts of Chomutov, Most, Teplice and Sokolov where these coal mines take up large areas. We do so with the help of remote-sensing-based documentation and GIS applications. Mining dramatically transforms the appearance of surrounding landscapes and has a high impact on the environment. The thesis shows the change of land use based on both the images from the Landsat satellite and the inclusion in basic Corine categories in which was created layer of land cover for 1990, 2000, 2006 and 2012, and further shows the ecological stability of the landscape from 1986 up to now. The evolution and changes of ecological stability are analyzed with the help of ecological coefficient, cluster analysis, linear...

Impact of stream and floodplain modification on th eflood effects on the example of Stropnice basin
Douděrová, Šárka ; Langhammer, Jakub (advisor) ; Matoušková, Milada (referee)
This thesis deals with the evaluation impact of the modifications of floodplain and river network to the course and consequences of floods on the example of Stropnice river, located in South Bohemia. The thesis evaluate causes, course and effects of the floods, that took place in the basin with special focus to the recent floods. The basin was hit by extreme flood in 2002, while in 2005, 2006, 2009 other floods with different origin and magnitude took place in the basin. The assessment was based on field survey, and application of GIS analysis of results for identification of critical stream segments, which may influence the course of flood events. To get information about river network modification the HEMF field survey methodology was used. The following rivers were mapped: Stropnice river, Svinenský, Klenský and Žárský brook. The critical stream segments are spread in the whole Stropnice basin. It can be concluded that the anthropogenic effects are apparent in the whole basin including its headwater part in mountains. In several critical stream segments there were proposed measures aimed to reduce the consequences of potential flood events.

Evaluation of suburbanization in Prague's hinterland - influence on landuse, landscape stability and structure.
Kubečková, Jana ; Kupková, Lucie (advisor) ; Štych, Přemysl (referee)
Evaluation of suburbanization in Prague's hinterland - influence on landuse, landscape stability and structure Abstract The aim of this study is to evaluate the background of suburbanization in Prague, to evaluate the development of landscape, landscape structure and landuse. The first part of this work is devoted to analysis of domestic and foreign literature, which deals with suburbanization and evaluation of landscape structure. Another part is devoted to practical evaluation of the landscape using air photos and satelite pictures and orthophotos in three cadastral in 1994, 2004 and 2007. It concerns the cadastral Šeberov, Hole u Průhonic and Újezd. The evaluations are based on selected factors. It is found that the proportion of buildings and vegetations is increasing all the time and also found that for example scrub and forests were protected from new development. Furthermore, the most significant changes in land use were described and the landscape structure was evaluated according to selected factors. The outputs of this work were maps of land use in different years, maps of stable und unstable areas in different periods, maps of vegetation changes and tables summarizing the results of the evaluation parameters of the structure. Keywords: suburbanization, landscape structure, landuse, patch,...

Landuse efects on the temperature regime of streams with focus on the habitat conditions for Margaritifera margaritifera
Summary
This bachelor thesis deals with the matter of the freshwater pearl mussel (Margaritifera margaritifera). It will describe the main factors affecting its reproduction and presence in the watercourse - the fresh pearl mussel is to be found among the endangered species and its presence and survival in a certain location depend primarily on the hosting fish which is the brown trout here in the Czech Republic. Generally, the main stress lays on the temperature and its influence on the ecology of the freshwater pearl mussel. This thesis contains a research part which describes the freshwater pearl mussel and impacts on it, and a practical part where you can find an assessment of the temperature and qualitative impact on growth and death of the freshwater pearl mussel during bioindications.
The temperature influences all age stages of the freshwater pearl mussel. The temperature changes thanks to a variety of different aspects such as surrounding flora in the watercourse, atmospherical factors, anthropogenic activity or altitude. You will be able to find all these aspects along with a percentage of their potential effect on the freshwater pearl mussel in this thesis as well as the assessment of the average summer temperature and its possible impact on any specimen of any stage.
The thesis is also based on the impact of surroundings on the freshwater pearl mussel which are discovered during bioindications that are also described here and have been partially used in the appraisal. The practical part of the thesis is focused on the growth and death of the species in the bioindication in five profiles of the watercourse.
The third part of the practical thesis is about locations that show surroundings and representation stated components. The reason I included this part is mostly for illustrative purposes which serve to expound the matter to the reader. The used data of components in the locations are from 2012.

Indicators of Spatial Sustainable Development
Maštálka, Martin ; Kyselka, Mojmír (referee) ; Mansfeldová, Alena (referee) ; Mgr.Michal Pondělíček (referee) ; Šilhánková, Vladimíra (advisor)
The aim of the thesis was to analyse indicators and data sets used in the field of sustainable spatial plannig. On the base of the analyses there were spatial indicators of the sustainable development designed. The basic condition to design new indicators it was the accessibility to the elementary datas. The other condition was to design very simply methodology that could be use also for measuring in very small location. The thesis designed idnicators in three main areas of the spatial planning: • landuse, • accessibility of the services, • inner city/town/village traffic. One of the demands for the new indicators set was it´s efficiency for all kinds of the cities in the Czech Republic. This demand was fullfilled by the 3 level methodolgy – the main indicator was measurable for all kinds of settlemets – small villages, small and middle towns and also for cities. The basic methodology (for small villages) was very simple. Indicators were computed from very easy accesible data sets. And this methodology could also be used for larger settlements without any problems. The second level – for small and middle towns – sometimes needs special surveys or special hardware and software. The top of the pyramid is the methodology for cities. In this level there are used detailed analyses and computing methods. The thesis designes the methodology and also checks the practical application up.

Mapping of scattered vegetation and planting design in selected cadastral area
SKALOVÁ, Jana
The aim of this work is to map the sparse vegetation in the cadastral Zachotín. It is a village located in the Kraj Vysočina and district Pelhřimov. Part of the description of the area was the creation of a digital layer of landuse and evaluation of land use. Sparse vegetation is an essential part of the landscape and its aesthetic expression. Apart from its aesthetic value is also important for the life and migration of animals and for the creation of anti-erosion measures. The paper describes all the scattered vegetation, assessment of their health status, function, size and species composition. They are also plotted in map annexes. Also included is a proposal scattered vegetation and supplement of existing elements.
