Abstract
Abstract Body
Since the turn of XX and XXI century when the green infrastructure (GI) concept has been developed, the greatest number of theoretical considerations and analysis of practical applications have been devoted to large cities. It is understandable because the greatest needs and, at the same time, the greatest problems with the development of GI concern these cities. To a lesser extent, the researchers seem to be interested in the smaller cities. However, in the case of Poland, according to the political declaration, small and medium-sized cities are to play an increasingly important role as significant elements of the national settlement network. The prospects for their development are related not only to the economic situation, but also to the possibility of providing residents with an appropriate quality of life. This, in turn, is associated with the benefits provided by GI. We assumed that the possibilities of creating a well-functioning GI depend primarily on the arrangement of areas covered with vegetation and waters. Thus, we examined the distribution of these areas in 116 small and 148 medium-sized cities. We conducted a quantitative analysis of the proportion of open spaces with landscape metrics. The share of the primary structuring land cover/land-use classes, for example: forests, agricultural land, grassland, water, was also investigated. The configuration of open spaces was described by a method combining landscape indicators with photo-interpretation of qualitative attributes. Based on these analyses one could distinguish 6 types of spatial models. On the basis of qualitative and quantitative analyzes, it was also possible to distinguish cities which, due to the area covered with vegetation and water, their layout (existing linkages included) and quality (dominance of forested or agricultural or other open spaces) are characterized by diverse potential for building a GI network.
