In my diploma thesis I focused on the diversity of weed species and the infestation in winter wheat and potatoes. The observations were carried out on the grounds of a family farm in Southwest Moravia. In the first part of the thesis I focused mainly on the history of farming systems, the aspects of crop rotation in crop rotation and the demands of the crops to be included in the sowing process. At the end of this section, I looked at spreading weed seeds, dormancy, and seed supplies in the soil. During the field research, I focused on weed species recording and counting of individuals. The most significant difference in weed species composition was found for seasonality, weed species spectra recorded in May differ significantly from species spectra recorded in August. The influence of the crop and crop rotation had much lower effect as well as differences among years or among grounds.

This thesis is focused on the maitenance of the Green vegetation on the higway, specialy for the central reserve median of these communications. The main theme of this thesis are mechanical lines used for these works necassary and financial cost of the mechanical lines. Mechanical lines for the Green vegetation maitenance are analyzed at the way of its work, the technique used and techniques position in the mechanical line. The next part of the thesis is devoted to an analysis of the finacial cost for work of the mechanical lines. Informations used for the calculations were obtained from the statemnets of the operating mechanical lines on the higway D2 at administration SSÚD 7 Podivín.

Dissertation topic "Reconstruction design of accompanying vegetation watercourse" deals with silvicultural measures, which will improve the current state of accompanying vegetation. This topic is dealt with on a specific model object. In the introductory part I deal with general problems of small watercourses, their divisions and characteristics. This part include as well bank issues versus accompanying vegetation. The functions of accompanying vegetation are also defined. In the next part of my thesis I deal with a specific model object, a broader territorial relations of area and its natural conditions. The current state of vegetation is critically evaluated and subsequently executed the proposal of reconstruction of the accompanying vegetation.

The county town named Hradec Králové is located in eastern Bohemia on the confluence of Elbe and Orlice rivers. It is situated in a flat area, with many green areas and the absence of heavy industry. The industrial activity is concentrated in small business - engineering, chemical, electrical and food processing industries. All these aspects of human activity may be associated with risk elements contamination of the environment. The town is characterised by the high traffic density; we can therefore also assume the presence of risk elements in the air and subsequently soil contamination in the proximity of these roads. The aim of the study was to analyze the level of contamination of soil and vegetation in the city caused by risk elements (As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, V and Zn). According to sampling scheme, which involved 86 sampling points, there were taken samples of soils and aboveground parts selected plant species: dandelion (Taraxacum sect. Ruderalia) and doorweed (Polygonum aviculare) occurring at all the sampling points. These samples were analysed for the risk elements contents. In most of cases the risk element levels did not exceed the maximum allowable limits for the content of elements in soil and plants given by Decree no. 13/1994 Coll. and Directive no. 2002/32/EC. In the case of soil, there were significantly higher values of potentially mobilizable contents measured for arsenic. But this was not reflected on the contents of this element in the vegetation when all results were below the detection limit of the analytical method. Rarely, the values exceeding the limits were observed in several soil samples in the case of lead and cadmium. While for lead no increased concentrations of this element in the vegetation was observed, the cadmium levels occurring in dandelion exceeded in several cases the limits for fodder crops. The ability of doorweed to accumulate the risk elements was lower compared to dandelion. Linear regression analysis showed that there is no significant relationship between the element contents in the soil and vegetation and the distance from the road. It therefore appears that the contents of elements in the soil and vegetation are not affected by traffic. Due to the significant positive correlation of most elements (except Cd and Zn) in the soil can be estimated that the levels in the soil are given rather by the character of the subsoil. This speculation but would require more detailed geological and geochemical survey of the site.

Evaluates current landscape and the landscape, which was already a fundamental discovery of species composition partially restored area by forest reclamation near the village Braňany . The affected area is processed solution proposal planting trees at the local municipality level, so as to achieve optimum smoothing effects of mining on the landscape and in terms of biological reclamation. The first section summarizes the historical development of brown coal mining in the Czech Republic but also in other important areas of logging, impact of mining on the landscape and the landscape, respect for reclamation or leaving the landscape of succession with regard to natural characteristics. In conclusion, this work is a concrete proposal, addressing state area to its original state, planting trees, bushes and trees, mostly domestic species. From the botanical point of view, there are no trees or buildings, which we They are having special attention. Natural forest community in the vicinity of Interest the area is in good conditionAfter extensive mining were some trees near the mining pits cut down, but the subsequent reclamation by planting at least partly achieved.

This dissertation deals with a temporal and spatial changes of woody vegetation at the landscape in West Bohemia. The case study helps to recognise a historical development of the landscape and focuses on landscape elements of forest and non-forest woody vegetation. Focused area was determined by borders of former Vrchlabi manor and based on historical documents. The chosen area partly belongs to zone 1, 2 and 3 of Krkonose National Park. Forest and non-forest woody vegetation was compared from different sources- a map of Imperial imprints of the stable Cadastre from 1843, an aerial images from 1950 and an orthophoto images from 2014 - using ArcGIS software. Woody vegetation was divided into forest category and other three non-forest woody category- draws, acompanying woody vegetation and line. The results have shown that the most consistent category has always been the forest, spreading on 42,25% of the area in last 171 years. The non-forest woody vegetation was developing erratically and was covering the largest area of 335,21 ha in 1950. Data analysis have shown that each period of forest and non-forest woody vegetation has its own specific trends.

Development of the technologies enables improving identification of surface objects by remote sensing methods. This thesis deal with classification of tree species and their spectral signatures. As an input data are used airborne laser scanned data, hyperspectral images with 72 bands and manually collected data about tree species. For classification there is used maximum likelihood method. Main results of this work are graphs representing spectral characteristics of tree species and raster classified by tree species.
