The aim of proposed thesis is identification and assessment of the impact of various types of vegetation cover on microclimate and local climate. The thesis study an issue of vegetation cover impact on the solar energy transformation, energy fluxes and an impact of vegetation cover on water cycle, mostly at the landscape level. Temperature-humidity characteristics and energy fluxes and their indicators (Bowen ratio, evaporative fraction) were monitored during the growing season in common types of vegetation cover occurring in agricultural landscapes (red clover - Trifolium pratense L., common wheat - Triticum aestivum L., potatoes - Solanum tuberosum L. and permanent grassland (TTP)) and wetland with predominantly tall sedge vegetation (e.g. Carex acuta L., Glyceria maxima (Hartman). Holmberg.). Results show a direct correlation between solar radiation and the amount of energy converted into latent heat of evaporation or sensible heat flux expressed through evapotranspiration. The results of analyses confirmed the theoretical assumption that the vegetation cover significantly influences microclimate, e.i. air temperature and humidity both of itself and surrounding area. The temperature-humidity characteristics were significantly different in the monitored stands. From this findings is obvious that the different types of vegetation can affect local microclimate differently. Moreover, the results showed that the vegetation well stocked with water probably significantly affects the water cycle in the landscape.

This thesis deals with permanent grassland, their meaning and use. The thesis is focused on the influence of water regime on selected grass species Kentucky bluegrass (Poa pratense) and Creeping thin (Agrostits tenuis), its resistance to drought, water stress and the impact of growth and production in the absence of water. The work was carried out under laboratory conditions and areas where attempts have been made regarding the germination of grasses in the absence of water. A sub-task was to evaluate dry matter yield for grass species.

The aim of this thesis was to judge a growth level of colts of the czech warm-blood under different conditions of breeding stations. 278 colts bred at testing breeding stations were observed in years 2001-2003. Their growth, exterior and movement mechanics were followed depending upon altitude of breeding stations, varying from 200 to 700 m above the sea level and were evaluated concerning ancestors of the genitor. Growth of 98 colts bred in 3 private keepings was followed and samples of green from 6 localities (24 habitats) in years 2005 and 2006 were analysed.

Aim is to assess the impact of farming methods and frequency of use of grassland on the yield and quality of forage biomass of grasslands and draft recommendations for use of certified grass.The observed area was around Kašperské Mountains, where, three different pastures. Botanical images were carried out in the pasture Lídlovy Dvory, Nebe and Ovčárna. Subsequently, analysis was performed with stand composition farming techniques.

Heterogeneity in forest vegetation monitoring with remote sensing Abtract The main aim of this diploma thesis is to examine the suitability of various classification approaches for forest vegetation categorization using Landsat 8 satellite imagery. Two satellite images acquired during vegetative period (8th March, 27th July 2013) were chosen. The overall goal of the study is to explore the potential of using statistical methods to obtain information about forest heterogeneity in a given territory. Chosen study sites are defined by administrative boundaries of selected municipalities from South and Central Bohemia located within following municipalities with extended powers - Blatná, Milevsko, Písek, Příbram and Sedlčany. Supervised and unsupervised classifications were used based on obtained training areas and orthophoto. The definition of chosen classes (coniferous forests, mixed forests, ecotones, structurally homogeneous deciduous forests and structurally heterogeneous deciduous forests) was identical with the categories used in "Project MT 11425-5/2010 The Mapping of Natural Zoonoses Focal Points, Transferable on Humans in the Czech Republic and Their Changes Affected by the Modification of Climate". Due to large amount of training datasets obtained from field survey, ortophoto and spectral analysis,...

The aim of this thesis was to define the issue of determining the administrative price and market value of forest in the Czech Republic. The thesis describes the evolution of methods of determining the price of forest in history since 1897. Furthermore, the thesis deals with the current problem of determining the market value of forest in the Czech Republic. The current situation is documented by a case study, which deals with the determination of the administrative price and market value. The study compares these two values. The final analysis is focused on recommendations of corrections of existing valuation regulations and method of market valuation of forest.

The aim of this diploma thesis is to elaborate a complex project of restoration of clearing due to salvage felling in the forest district Odry and reconstruction of the spruce in the district of Heřmánky. The forest districts are under the administration of the state enterprise Forests of the Czech Republic, specifically under the Forest Administration of Vítkov. The project includes an analysis of causes of declining and dying stands in the selected area, stand condition, condition of clearings and young plantations, site preparation, methods of woody species and methods of recovery, protective and defensive methods of established plantation, direct economic costs.

This diploma thesis evaluates the commencement of phenophases considering the changing microclimate conditions in the habitat of Norway spruce (Picea abies /L./ Karst) in a young and a mature spruce monoculture at the ecosystem station Rájec. The phenology of spruce undergrowth has also been under observation. Regarding the methods, above-ground phenology and observation by means of phenocams have been used. The results have been compared not only among themselves but also in the context of long-term averages. Thanks to the fact that phenophases of forest woody plants and herbaceous plants are dependent on climate conditions, the results of long-term phenological observations are a conclusive indicator of climate changes. The results of this diploma thesis can be a contribution to the phenology database.

This diploma thesis deals with influence of fertilizing and usage intensity on species composition and primary production of semi-natural grassland. The issue was solved through an experiment at Kameničky stand, which is located at Bohemian-Moravian Highlands at an altitude of 650 m. In the experiment were evaluated variants of fertilizing: non-fertilized, fertilized P30+K60, fertilized N90+P30+K60 and fertilized N180+P30+K60 with a double-cutting and triple-cutting usage intensities in 2014 and 2015. The results showed, that nitrogen fertilizing promoted the development of grasses (P<0,05) and reduced the proportion of clovers and herbs (P<0,05) in the stand. Phosphorus and potassium fertilizing in the stand increased proportion of clovers at the expense of herbs. Beside 2015, conclusive higher proportion of clovers was in the stand in 2014 (P<0,05). Double-cutting intensity of usage promoted numbers of grasses and decreased numbers of clovers in the stand. Triple-cutting intensity of usage increased proportion of clovers in the stands, which were richer on species. Triple-cutting stands had higher Hill's diversity index, which was decreased with higher fertilizing intensity, same as number of species in the stand. Fertilizing conclusively increased yields of dry fodder (P<0,05). Double-cutting stands indicated higher yields of dry fodder (6,46 t.ha-1) than triple-cutting stands (5,96 t.ha-1). Beside 2015 (5,68 t.ha-1), higher yields of dry fodder (6,74 t.ha-1)were in 2014 (P<0,05).

The diploma thesis assesses the current state of the Hulín gravel and sand plant and pays attention to abrasions of severely damaged banks of the reservoir. With the help of the design of a suitable biotechnical stabilization, the receding of the shoreline in the section of interest will be prevented. The basis for the processing of appropriate bank stabilization proposals is the results achieved using a method of determining shore retreat. The individual developed variants of the bank remediation solution emphasize the use of vegetation support, especially suitable bank stands to ensure the stability of the banks and protection against abrasion.
