'NATURA 2000' NETWORK AND THE STATE OF LOCAL ECONOMY OF THE RURAL AREAS OF THE 'GREEN LUNGS OF POLAND' REGION - THE APPLICATION OF MODELS (Siec Natura 2000 a stan lokalnej gospodarki obszarow wiejskich Zielonych Pluc Polski - ujecie modelowe)

In the paper models of regressive trees were used to illustrate the shaping of the agricultural sector's condition and economic activity of the residents of rural areas in the 'Green Lungs of Poland' region. These models were prepared in an effort to empirically check the pessimistic assessments of the state of the local economy of communes situated in the 'Green Lungs of Poland' region, which are broadly covered by special protection of birds and habitats within the 'Natura 2000' network. The models' results presented simple criteria for distinguishing communes with different levels of the development of economic activity and agriculture. They also made it possible to assess the validity of the used predictors that constituted the sub-components of sustainable development distinguished in the research project. The results of predictions of the models of regressive trees were shown on maps, which permitted to make an assessment of the spatial shaping of local economy in the areas of the 'Green Lungs of Poland' region.
