Conteúdo: | The presenee 01 vegetation in cities has been eonsidered synonymous 01 lile quality. Cities are altered environments; its vegetation is remnant frorn natural areas or originated frorn implernented areas such as public areas (parks, gardens and squares), around streamlets and rivers ar in private areas (residences and industries). It is neeessary a good diagnosis 01 the presence 01 vegetation in urban plan to serve 01 inforrnation to irnplant green areas and rnanipulate the existing tree cover. The quantification 01 known as green existent elements in the cíties is importarft to guarantee a minimum of well-being for the population. T he challenge nowadays is how to quantify these elements and to determine how they are related each other. The objective of this study was to propose an index to assess the quality of plant eover in relation to its ecologieal lunction in the urban environment. The index was elaborated using surveys 01 sidewalk trees, digital plans, aerial photography and videography to measure the areas oeeupied by the vegetation. The methodology to obtain the IOEVUe considers the lollowing prerequisites: a) The index must broadly represent the quality characteristics 01 lhe urban green spaces; b) The number 01 parameters to be assessed must be the smallest possible, but they need to be chosen in order to represem ali lhe relevant eharaeteristies 01 lhe green spaee. frorn the point 01 view 01 lhe eeological functions; e) The index must contain the direet contribution 01 sidewalk trees; d) Temperatura. hydrology and carbon lixing are parameters that have to be eonsidered lor ali green spaces: e) The index must be a number pure. without any measurement unit beeause it expresses a "qualíty". The landscape unit chosen for the study was the Santa Cecilia neighbarhood, Piracicaba, São Paulo State, Brazil. Obtaining a so-called "Urban Green Space Quality Index" IOEVU for urban open space assessment was discussed. speeified for the ecological lunction, and thus called "Urban Green Space Ouality Index with Eeologieal Functíon" (IOEVUe). The assessment parameters lor the latter index were: si1ading by sidewalk trees. hydrology. carbon fixing and temperature influence, for ali the green spaces.
