description:
The aims of the project are to quantitatively estimate possibilities to use different indicative parameters of cartographic origin (soil map, base map, relief model, remote imagery) to predict habitats, plant cover and nutrient cycling in the landscape. To estimate the weight and indicative value of the impact of surrounding of different distance to different empirical data and to find effective methods for evaluation of the impact of surrounding. To analyse the relations between landscape fragmentation and selected parameteres of bird habitats and plant cover and to estimate the possibilities to predict the parameter values.

To create a combination of GIS and dynamic point model useful for planning and wide analysis and thus, to establish a possibility for soft planning of land use for nature conservation by suggesting the location of grassland/forest/arable land. To create algorithms for defining the source and sink areas of nutrients and classification of them by nutrient flux intensity useful for planning and environmental impact assessment as well as a tool to analyse the impact of climate change to nutrient fluxes.

The expected scientific results of the project are effective methods for estimation of the weight and indicative value of the impact of surrounding, better understanding of the spatial-temporal impact of landscape parameters to nutrient cycling and biota, development of the dynamic model of nutrient cycling with main attention to climate change, expected practical results are suggestions for better planning of natural resource management and nature conservation.
