Eixos de crescimento urbano e arborização em Ponta Grossa - PR

Abstract

The afforestation of cities is an element of great importance for optimizing the quality of life, whether in small towns or large cities. Currently, urban trees is essential in any urban planning. The interest in researching Urban Forestry lies in understanding the relationship between the axes of urban sprawl and the spatial configuration of the afforestation of public streets of Ponta Grossa, between the years 1960 and 2012, highlighting the changes for which the city are going through, what are the axis expansion with emphasis on neighborhoods Young Russia, Central and workshops with the identification and quantification of tree species. To highlight the axes of urban expansion was used Berto's work (2004) that when performing the mapping and analysis of land use in the city of Ponta Grossa, identified the main areas of urban expansion between 1960 and 2004 and an update for the year 2012 for the tree inventory used the CAP (Circumference Breast Height) greater than or equal to 20 cm concurrently with the process history of each neighborhood. The results showed that increased from Ponta Grossa city with characteristics essentially rural to a city with urban characteristics. The afforestation is present in the Directors Plan, but inconsistently. The correlation between tree inventory of the neighborhoods included in the axis of growth of the city shows that the neighborhood of New Russia and Central have a greater number of individuals due to their occupation and neighborhood workshops to be essentially a working class neighborhood during the construction railroad, not presented in its history any mention of individual trees that deserve emphasis, but also observed a significant number of lanes without espécies.As species that stood out were those commonly known as extremosa, privet, ficus and palm jerivá, among them the exotic significant number, since the specific actions of the municipal administration did not happen in a planned manner. This research is focused on understanding the spatial dynamics that result from nature-society interaction in the urban space of the city of Ponta Grossa and aims to contribute to both the scientific community and to society and municipal managers.
