Most ecosystem services assessment tools attempt to quantify services on a landscape scale using simplified biophysical models or ecological functions. The most commonly used ecosystem classifications are land use / land cover or habitat, which can be combined with other information such as soil type or vegetation biomass. The aim of the study was to quantify selected ecosystem functions in the cities of Liberec and Děčín. For the evaluation of habitat biodiversity in 2003, a complete list of habitat types was prepared for the Czech Republic, which includes habitats processed in preparation of data for the creation of a national design of Natura 2000 sites of European importance (Habitat Catalog of the Czech Republic 2001 and 2010) and detailed description of more antropgenic influenced habitat (Sejak et al., 2003, Sejak et al., 2017). For 21 functional groups of habitat types, their production function, including oxygen production and the ability to minimize temperature fluctuations (to reduce the amount of radiated heat) was estimated to provide support and regulatory services to ecosystems (Seják et al. 2010). According to the assignment of the study, Elaboration of the layer of provision of selected ecosystem functions and services in the area of interest of the cities of Liberec and Děčín, biodiversity values determined according to BVM method, annual biomass, oxygen and evapotranspiration production for the entire cadastral territory of Liberec Kunratická and dam Harcov and for the cadastral area of Děčín.

Valutation of ecosystem services provided by habitat on the basis of biodiversity characteristics and the rate and sustainability of selected ecosystem functions
Cudlín, Pavel ; Prokopová, Marcela ; Cudlín, O.
Increasing human impacts on ecosystems result in a continuous decrease in biodiversity; scientists try to estimate the consequences in ecosystem functioning and ecosystem service (ES) provision. A suitable space framework to study this relationship could be the habitat and its relative value expressed by the monetary valuation of a selected fi nal ES. A cross connection of the methods for ecosystem functioning assessment with biodiversity valuation of habitats would enable an estimation of the role of biodiversity in ES provision. It is necessary to identify not only present functioning, described by eff ect traits, but also its sustainability under global environmental change conditions, described by response traits. Th is approach could reveal the resilience and adaptation potential of present habitats to environmental change and subsequently potential changes in ES provision.
