Analýza změn rozšíření invazního neofytu rodu křídlatka (Reynoutria spp.) v povodí Morávky

Abstract

This bachelor thesis analyzes the changes in land cover in the watershed knotweed Morávka. The incidence of knotweed is a negative phenomenon in terms of reducing the diversity of other plant species. Data were obtained using GPS mapping areas with occurrence of knotweed. The incidence of knotweed was mapped in 2007, 2009, 2013. The mapping was conducted by RNDr. P. Švec, Ph.D. Solutions are dependencies between the selected attributes. This is a demonstration of statistical dependence using the chi-square test of goodness of fit and ANOVA. Were also created tables and graphs presenting the values of selected attributes. In particular, the total area in each year. Geodata created map outputs for the purpose of presentation. For them, the cartographic method was used bivariate map. It displays two different attributes in a map field at the same time. Results of statistical tests and mapping output are described and partially justified.
