Accessibility of urban green spaces (UGS) is an integral element of satisfying quality of life. Due to rapid urbanization, the studies about UGS are becoming one of the key elements of urban planning. Functional network transport system and optimal spatial distribution of UGS are preconditions for maintaining the environmental balance of the urban landscape. Accessibility analysis of UGS in the settlement of Zadar was conducted as a part of the Urban Green Belts Project (UGB). Development of spatial database was the first step in generating UGS accessibility indicator. Data were collected using the supervised classification method of multispectral LANDSAT images and manual vectorization of high-resolution digital orthophoto (DOP). An analysis of UGS accessibility according to Accessible Natural Greenspace Standard (ANGst) was conducted. Accessibility indicator was generated based on seven objective measures which include the UGS per capita and accessibility of six UGS functional levels. The UGS accessibility indicator was compared with subjective measures that have been obtained by field survey of 718 respondents within 41 statistical units. The collected data reflected an individual assessment and subjective evaluation of UGS accessibility. This study illustrated the importance of using objective and subjective measures in the process of understanding UGS accessibility. It may be concluded that while evaluating accessibility, the residents emphasize the immediate residential environment, neglecting the UGS of higher functional levels. Furthermore, that large amounts of UGS within a city (114 m² per capita) do not necessarily generate a similar satisfaction with their accessibility. The output results may serve as guidelines for the further development of the functional UGS city network.
