Fast-growing trees as a renewable energy source
Žvaková, Veronika ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This bachelor thesis is focused on biomass as a renewable energy sources. The main topic is fast growing trees and their effects on biological diversity, the local ecosystem and landscape ecology. Literature survey was conducted regarding using this kind of biomass in the Czech Republic. Thesis reviews technological methods of cultivation and treatment of fast growing trees.

Vliv stanoviště a agrotechniky na produkci fytomasy vybraného klonu topolu (Populus nigra L. X Populus maximowiczii Henry) pro energetické účely
NOVÁKOVÁ, Aneta
The thesis deals with theme of fast-growing species and with the impact of agricultural practices (like choice of location, care and possibility of fertilizers usage) which are the most important factors for successful cultivation of energy tree species. The introductory part of the thesis contains an explanation of the term biomass and its possible distribution by types and ways of obtaining the biomass. Following chapters deal with fast-growing tree species. The issues of cultivation are also described here in parts like basic characteristics, history of these energy species, legislative restrictions and procedure during founding of the plantation itself, selection and preparation of locality, the use of agricultural practices (cultivation, fertilization). The practical part deals with it´s own experiment with a clone of poplar J 105 (Populus nigra L. x Populus maximowiczii Henry). This clone of poplar was planted on four experimental plots. The growth depending on the conditions of habitat and selected agritechnical measures was observed in following years. There are descriptions of conditions on all localities, chosen ways of planting and aftercare about tree vegetation. Another experiment which contained adding different types of nitrogenous fertilizers was performed in the last period of observing. Results showed that the greatest impacts on the quality of the growth of fast-growing trees have properly chosen location and aftercare about tree vegetation, at least in the first vegetation period. Addition of fertilizer seemed as important only in case of planting on nutrient very poor sites.

Fast-growing Trees as a Tool for Preventing the Impacts of Climate Change
Humešová, Tereza ; Syrovátka, Oldřich (advisor) ; Weger, Jan (referee)
This work was created as a response to the drought in the summer of 2015, which revealed the risks associated with a lack of moisture in the soil due to inadequate management landscape. The main objective is to select areas in the chosen territory where it would be desirable to implement measures that would lead to stabilization of drainage conditions, and support the landscape and territorial system of ecological stability (biodiversity).In addition to creating the appropriate landscape features and the introduction of environmentally friendly agricultural crops eligible planting fast-growing trees (FGT), which on agricultural land, for the interest of stabilizing of drainage conditions, in many ways irreplaceable alternate functions of the forest.This culture is therefore paid special attention; Work has focused on the estimation of the possible production of wood and possibility of its eventual use.The study is prepared as a possible basis for practical solutions to complex land arrangements in the cadastral areas. It was found that the FGT would be advisable to cultivate an area of up to 2461 ha.

Attitudes Management of large Farms to Produce fast-growing trees
Zelenková, Aneta ; Syrovátka, Oldřich (advisor) ; Duchek, Stanislav (referee)
The aim of this thesis was to ascertain the attitudes of management of selected large farms operating in the South Region in the production of fast-growing trees on-the-agricultural land and attitudes to the concept of greening. To fulfill the goals of this thesis were used questionnaires - a structured questionnaire sent by e-mail after prior phone contact. The research covered 18% of cultivated agricultural land throughout the South Region. They were classified according to the jurisdiction of the district. It was found overwhelming preponderance of negative attitudes towards the production of SRC and reasons for this opinion. Production is dedicated to one of the thirty producers. The concept of greening is considered inconsistent. Positive attitude toward greening occupy a particularly company with combined agricultural production, negative attitude then producers od crop production.

Studies resources for local heating in Sezimovo Ústí
Ledvinková, Markéta ; Syrovátka, Oldřich (advisor) ; Vetýšková, Lenka (referee)
The theme of bachelor's thesis is " The study of resources for local heating in Sezimovo Ústí." The target of thesis is determinate the present structure of heat sources which are used by inhabitants in the city of Sezimovo Ústí, citizens satisfaction with local heating and air situation which occur with each winter season. In addition, their attitude and awareness of the fast-growing trees and, utimately, their possible interest in the case of an offer to change heating and the factors affecting this decision

Effective use of phytomass in the protected area of the National Park Podyjí
FORMANOVÁ, Petra
The objective of the thesis is to evaluate the possibility of the effective use of waste and phytomass specifically grown for energy purposes in the protected area of National Park Podyjí. The task was to characterize the source of phytomass in this environmentally sensitive area. The data were collected by studying documents, visits to enterprises and institutions, and personal consultations with business and other stakeholders. The result of this work is a brief assessment of the production potential and the factors influencing its development. Due to the nature of the territory, to suggest measures for efficient use of land for the production of energy phytomass with regard to the attitudes of farmers and the authority of nature and landscape.

Possibility of Increasing the Share of fast-growing trees in the Local Energy selected Municipalities
Pátková, Michaela ; Syrovátka, Oldřich (advisor) ; Hora, Petr (referee)
The work on "Options increase the share of fast-growing tree species in selected local energy community" to deal with the question of under what conditions it would be possible to increase the share of fast-growing wood (RRD) in the local community energy Stržanov. In the theoretical part summarizes the particular information about renewable energy and the cultivation of fast growing trees, she is also the issue of ecological stability of the landscape to which RRD production contributes to the business plan. Investigation of the village Stržanov focused primarily on the present structure of resources, fuel and attitudes of the population towards the possible introduction offers fast growing trees grown on agricultural land. The practical part is the calculation of the area of SRC plantations to supply the village Stržanov and their impact on the value of the coefficient of ecological stability (KES).
