Für den Anbau von Biomasse-Dauerkulturen wie schnellwachsende Baumarten werden Anbauhinweise und -empfehlungen gegeben, die Aspekte des Boden-, Gewässer- und Naturschutzes berücksichtigen. Standorteignung, Wirkungen auf wildlebende Pflanzen- und Tierarten, entstehende Synergieeffekte, Einflüsse auf den Wasserhaushalt, Stoffeinträge in Gewässer sowie klimatische Wirkungen sind Teilaspekte, unter denen die Chancen und Risiken der energetischen Nutzung nachwachsender Rohstoffe im Rahmen eines mehrjährigen Verbundvorhabens in Sachsen untersucht wurden. Ergänzend wurde auch der Anbau einjähriger Energiepflanzen betrachtet.

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.

This thesis deals with the partial evaluation of the life cycle of three kinds of power plants, particularly flint corn ( Zea mays L.) , reed canary grass ( Phalaris arundinacea L.) , Szarvazi I ( Agropyron elongatum L.) and their environmental impact during their cultivation. As an evaluation framework was used seedbed preparation time from the first year to the last harvest after ten years growing cycle. To calculate the emissions of greenhouse gases has been used software tool SimaPro . The aim was to find out how much greenhouse gas emissions (kg CO2eq per 1 kg of dry matter ) is created in the cultivation of selected power plants and compare that plant is from an environmental point of view the most environmentally friendly. The total emission load produced during the life cycle of corn is sown CO2eqv 0.199210 kg per 1 kg of dry matter , with reed rákosovité CO2eqv 0.182075 kg per 1 kg of dry matter. I Szarvasi is from an environmental point of view the most friendly CO2eqv produces 0.110232 kg per 1 kg of dry matter.
