Changes in landscape in the catchment of water-supply reservoirs Švihov and Vír I
Červeňanská, Karolína ; Lipský, Zdeněk (advisor) ; Kučera, Tomáš (referee)
This thesis deals with the analysis of landscape changes using the index of change and the index of development in the catchments area of our two key water reservoirs Švihov and Vír I using CORINE Land Cover and LUCC Czechia data from the time of their building to the present, with a particular focus on the landscape changes in particular protection zones. The theoretical part of the thesis focuses on the reservoirs, the legislative background of water protection and the interaction between water reservoirs, landscape and people. Furthermore, the thesis deals with the concept of landscape and especially with the development of landscape and population in our country from the middle of the 19th century to the present. The importance of the two reservoirs is also described, including their physical-geographic characteristics and the history of the delineation of the protection zones in their catchment areas. In the practical part, the observed time horizons, the selected territorial units and their delimitation within the protection zones are specified in more detail. In the chapter of Results, the observed changes in landscape cover, land use and population are described, both for the entire catchment area and in more detail for the particular protection zones in all the periods studied. The...
Assessment of disused sand and gravel pits in the Třeboň region from the perspective of landscape ecology
Eliášová, Kateřina ; Matějček, Tomáš (advisor) ; Lipský, Zdeněk (referee)
This thesis summarizes findings gained about abandoned sand and gravel pits located in the Třeboňsko Protected Landscape Area. A study of written documents, old maps, aerial images and a field survey of selected sites were used to find out information on mining and mining pits. In the survey, erosion of mining walls, pollution, land use, land cover, dominant and invasive plant species and moisture of mining pits were monitored in sectors of approx. 1 ha or the bank length of about 500 m. A total of 127 sites was included, 37 of which were surveyed in the field. A classification has been created based on age, size, moisture conditions and current land use. Changes caused by mining, including changes in land use and land cover before and after mining, as well as the interaction of mining sites with the Territorial System of Ecological Stability (ÚSES) were also monitored. The majority of sand and gravel pits are small with an area less than 1 ha, dry pits predominate, and most sites were abandoned in the 1970s to 1990s. In about half of the cases, the land cover or land use from before mining have been restored. The main land cover change is the formation of large lakes and forests while the non-forest surface is more diversified after mining. Sites converted into arable land or built-up areas are...
Mapping and documentation of landscape important elements in the area of Novodvorsko.
Michalová, Edita ; Lipský, Zdeněk (advisor) ; Skaloš, Jan (referee)
The Master's thesis deals with mapping and documentation of important landscape elements in cadasters Nové Dvory, Svatý Mikuláš and Rohozec. Important landscape element represents ecologically, geomorphological or aesthetically valuable part of the landscape that shapes its typical appearance and helps to maintain its stability. This category of general nature and landscape protection allows to protect the segments of the landscape, which do not have the parameters for publication in specially protected areas. Field mapping and selection of important landscape elements were made on the basis of basic maps of 1: 10 000 and color orthophoto. Selected elements of the landscape was divided into several categories and documented using the tables. Elements of each category were evaluated on the basis of monitored parameters and the available sources. Also the map of important landscape elements was created. In the territory was documented 120 important landscape elements belonging to the nine categories - forest, water, rivers, riparian vegetation, alleies and line of trees, permanent grassland, wetlands, islands of trees and cultural and historic elements. The found important landscape elements play in the cultural landscape, where there are not specially protected areas of nature, an important and irreplaceable...
Postauditing in the EIA process
Kohoutová, Michaela ; Braniš, Martin (advisor) ; Lipský, Zdeněk (referee)
Environmental impact assessment (EIA), its key principles and aspects, these are themes discussed worldwide. EIA is useful as an environmental prevention tool but its effectiveness is seen in many cases in a bad light. The causes of the inconsistency between an opinion and the subsequent actual state are manifold and as we can see in the academic literature, it is becoming increasingly necessary to examine the need for monitoring and post-project analysis. Measures for reducing environment risks through monitoring and post-analysis, together with EIA opinions and assessments of its accuracy, are becoming important themes mentioned in the scientific journals. This work comprises a consideration of the choice of adequate methods and initial questions whose correctness is crucial for a successful prediction. Effectiveness of the EIA process depends on an appropriate methodology, existence of data in EIA documentation and other aspects, which are often discussed in the scientific literature. The object of this work is to define the environmental impact assessment (project analysis) in relation to the actual state of the territory (post-project analysis), to describe the advent and the historical aspects of environmental impact assessment in the Czech Republic and abroad, and to compare the correctness and...
Assessment of the impact of wind calamity from November 19, 2004 on the nature of the High Tatra Mountains
Vosátková, Veronika ; Lipský, Zdeněk (advisor) ; Matějček, Tomáš (referee)
The aim of this study is to bring a light into the situation of wind calamity which happened 19.11.2004. After the physicographical analysis of this locality, I will try to bring the whole picture of this catastrophe, its causes and mostly consequences left on the tatra nature. I will pay special attention to regeneration of the country and following steps in dealing with this calamity because of two different opinions on the picture of Tatras. Finally, I will discuss future progress in Tatra mountains and i will try to answer the question, whether was a worse catastrophe a wind calamity or human intervention in this locality afterwards.
Assessment of ecomorphological state and land use of Bylanka and Chotýšský brook flood plains
Slavíková, Pavlína ; Lipský, Zdeněk (advisor) ; Matoušková, Milada (referee)
This diploma thesis is dealing with geoecological assessment of water courses in the Bylanka catchment. The model area is situated in the Central Bohemia in the district Kolín. The catchment has a character of flat hilly country with the highest altitudes over 400 m. Most of the area is used as fields, forests cover only 9 % of the territory. Bylanka (8,4 km) and its longest affluent Chotýšský brook (10,6 km) were chosen as model water courses. The geoecological assessment is composed of three different methods. Ecomorfological assessment (Matoušková, 2003) was used for water courses evaluation. This method divides the stream and its surroundings into 4 ecomorfological zones: stream channel, vegetation belt, flood plain and water basin. The final ecomorfological state is better in the case of Bylanka because this stream is less anthropogenic transformed due to deeper erosive incision in the Permian-Carboniferous formations where human couldn't change the stream flow. Proliferation of bank and riparian vegetation is the second method of water courses and its surroundings evaluation. White willow (Salix alba), black poplar (Populus nigra), aspen tree (Populus tremula) and common alder (Alnus glutinosa) are the most frequently occurring wood species. Land use changes in the flood plain of Bylanka and...
Landscape typology in the area of the Bohemian Paradise
Merhautová, Zuzana ; Lipský, Zdeněk (advisor) ; Romportl, Dušan (referee)
Landscape typology deals with the classification and description of cultural and natural landscape. European landscapes are going through irreversible changes that are mainly caused by intensive agriculture as well as they are affected by phenomenas such as globalization and unification. The traditional structure of the European landscape is disappearing. Landscape typology can serve us as a base for monitoring of these changes. There are many different methods of how to classify the landscape, which is a complicated object of interest. This thesis presents the landscape typology in the area of Bohemian Paradise using the objective statistical method of cluster analysis. Cluster analysis is a set of tools for building groups (clusters) from multivariate data objects. The aim is to construct groups with homogeneous properties - landscape types. To classify the landscape of Bohemian Paradise, only quantifiable data in digital format were used. Land Cover, relief, moisture and soils were included in input layers. The classification was made in Twinspan - a software using the ordination method to classify the landscape in the divisive hierarchy. The typology of the area of Bohemian Paradise was divided into four hierarchical levels and at the last fourth level 16 types of landscape were identified. The results...
