The aim of this thesis was to determine the response of trees to air pollution in the city. For this purpose, APTI index (Air pollution tolerance index), the measurement of chlorophyll fluorescence and the analysis of the content of photosynthetic pigments were used. The examined trees were Platanus acerifolia and Prunus subhirtella v. autumnalis rosea growing in Lannova třída in České Budějovice. For evaluation of APTI index, four parameters are required. These are the quantity of ascorbic acid and the photosynthetic pigments in the leaves, the relative water content in the leaves and the leaf extract pH. The samples of leaves were taken in August 2015. From Lannova třída, three trees of each species were chosen. This research has showed that in terms of evaluation APTI index of Platanus acerifolia is more tolerant and less sensitive to air pollution than Prunus subhirtella. The value of the APTI index at the Platanus acerifolia was 9,33, at the Prunus subhirtella APTI index was 7,84. During the evaluation of the maximum photochemical efficiency of photosystem II, statistically significant differences between the trees were not found. The values obtained via the method of chlorophyll fluorescence at both tree species were low, at the Platanus acerifolia it was 0,65, at the Prunus subhirtella it was 0,68. In terms of content of photosynthetic pigments, Prunus subhirtella has come out better. In almost all, it had greater content of pigments than the Platanus acerifolia. The results of the research were used in the draft for excursions for students of 7th grades of elementary schools to this area.

The study deals with a proposal to deal with an area of 27 hectares in the city of Brno - Center. The premises of the former military warehouses on a plot between the streets of Veveří, Pekárenská, Kounicova and Sokolská. At present there are used by supermarket, other buildings deteriorate and are intended for demolition. At the southern corner of the parcel is located on the street Veveří tram stop. From here you can easily walk through the plot in Kounicova street, but the current state of the environment at the site of the area devalues the experience of being in such a space and aesthetics due to the surrounding historic buildings. The dominant element on the corner of the parcel is a protected sycamore. The proposed structure is suited to the current understanding of the world. Combines resources for intensive way of life with the necessary convalescence and his need for space with greenery, calm and light. The concept uses a nautical elements inserted into the context of the Czech Republic and simultaneously builds on Brno functionalism.
