One of the leading causes of biodiversity loss is the destruction, deterioration and fragmentation of ecological systems, especially by agricultural and water management policies and practices. In the last years, numerous monitoring and research programs focusing on ecosystems changes at global, regional and local level were implemented.
Studies regarding ecosystem dynamics provide extra information on the status of integrated organizational levels of biodiversity. The aim of this paper is to describe the temporal dynamics of the spatial distribution of the ecological systems from the Neajlov Catchment Long Term Socio-Ecological Research site. The analysis is focused on changes of ecosystems spatial configuration occurred from the beginning of the 20th century up to the present within the area based on cartographic information.
The identification of ecological systems distribution was done using Geographic Information System (GIS) and by analyzing the dynamics of different structural parameters. The spatial and temporal analysis of ecosystem distribution in Neajlov Catchment site showed that, in the last century the forest surface decreased, wetlands and aquatic ecosystems shrank to less than half as result of spatial extension of agro- and socio-economic ecosystems. Over the last decade, the number and surface of protected areas has increased, in an effort to reduce the rate of the biodiversity loss. |
