Starting from thisdefinition, one can assert that the quality of theurban green space is the ensemble of positiveresponse effects to the biological and socioeconomicalneeds of urban existence, but alsoto the need of urban ambience defined by thepsyche-social needs of spatial identity andaffiliation to the cultural landscape.MATERIALS AND METHODSThe quality of urban green space is assignedthe meaning of quality-value as a positivecharacteristic which results from two types ofmeasurable and immeasurable characteristics:1. Primary qualities which respond tobiological and socio-economical needs bydirect effects in the general state of health, ofthe environment and of micro-climate.2. Secondary qualities which respond to thepsyche-social needs through indirect effects onthe psychological planThe quality of the urban green is directly andmandatory involved in the quality state of theurban environment through its positive andeffects in the different areas of interest: spatialplanning, functional, aesthetic-ambient and381ecological, having unchallenged effects in theensemble of life quality.The environmental factors which affect theurban space (climate, soil, landscape, biologicaland anthropical) also influence the quality ofthe green spaces, through a multitude ofcomponents (social, physical-chemical,inorganic and organic) which affect the state ofbalance of the urban ecosystem and thus thequality of the green infrastructure from the city.There can be made the assertion that theecological field related to the quality of urbangreen is far more ample in proportion to theclassical approach – through the functionalaestheticbinomial – and that it presumesinterdependency relations between the fields ofspatial-functional, aesthetic and ecological. Theclassical approach of quality by means of thefunctional-aesthetical binomial and theimplication of the ecological factor conduce tothe idea that the parameters of functionalityrepresent criteria for evaluating the quality ofurban green spaces, having as the result theefficiency in using the planted areas of the city(by enhancing the degree of socialization).RESULTS AND DISCUSSIONSThe synthesis of the criteria and determinantfactors of the urban green quality (Table 1) willtake into consideration 4 levels of approach:physical, functional, aesthetical and ecological.Each of these approach levels is determined bya series of components, significance, criteria
