“…The classical utility-based theory emphasizes the scope of services for public facilities (Taleai, Sliuzas, & Flacke, 2014). I therefore calculate the total population (PPGSs) and communities (CPGSs) within the service scope of PGSs to indicate the accessibility (Lee & Hong, 2014). More specifically, I set a 1.0 km distance threshold as the service scope because it is the acceptable distance for residents to visit PGSs (Giles-Corti et al, 2005).…”

Abstract:In recent decades, the ever-decreasing number of green spaces have become insufficient to meet public demands in terms of accessibility, spatial distribution and the size of urban green areas. This is mainly due to increasing attention on the issue of accessibility to urban green spaces. This paper aims to quantify accessibility according to existing qualitative and quantitative characteristics of urban green spaces (UGS) in Çukurova district in Adana, Turkey. Firstly, qualitative and quantitative characteristics of UGS are divided into five main categories: area size, amenities of the UGS, transportation, focal points and population density. A set of 59 criteria are used by referring to the literature and expert views. Secondly, the Weighted Criteria Method was used to determine the significance of levels within these criteria and the existing situation of each park was identified and scored via field work. Thirdly, accounts of the distance of UGS service areas distance from people or users were optimized according to the total scores of existing UGS sites. Finally, the service areas of UGS were mapped by using Network Analysis tools. Results highlight some practical implications of optimizing accessibility for urban planning, for instance, specific land uses might be chosen for highly accessible UGS particularly those characterized by their high area size and equipment variety, low population density, and proximity to units.

“…This model was first developed by I. L. McHarg for assessing suitability for landscape planning [53]. With the capacity to integrate multiple factors from different fields, this model is continuously expanding to assess supply and demand of UBGI [43,54], development suitability [55,56], and ecological sensitivity [57]. Following this model's basic principles and existing research [35,43,57,58], the distribution of the assessment values was taken, which informed the range of each variable in this study's grading system ( Table 2).…”

Urban blue infrastructure (UBI) and urban green infrastructure (UGI) can be seen as an integrated system in which services and spatial layouts complement each other. However, given its complexity, it is difficult to integrate and optimize the layout of urban blue and green infrastructure (UBGI) in the built environment. This study develops a planning support tool for the layout integral optimization (PSTLIO) of UBGI. Using Hekou City in China as a case study, service demands and the supply of suitable land for UBGI development are assessed and mapped on geographic information system (GIS). The potential areas for UBGI development are delineated after mapping assessments of service demand and land supply and suitability. Following discussions on the exact means for PSTLIO to support the layout optimization of UBGI, a PSTLIO-based solution is developed to structure the UBGI link network and hub system, define the functions and service patterns of single UBGI components, and provide guidance for determining the scale of UBGI components. The results show that PSTLIO is able to provide a quantifiable base for decision-making in UBGI layout optimization.Sustainability 2020, 12, 1613 2 of 22 solution, UBGI could also provide an abundant base for urban ecosystems, in which diverse ecologies and networks could be conserved [12,13]. Moreover, the effects of UBGI in regulating the urban microclimate were also explored in recent studies [14]. It was proven that UBGI could cool urban areas through evapotranspiration, shadowing, adjusting emissivity, and affecting air movement and heat exchange [3,15], indicating UBGI's huge potential in relieving the urban heat island effect (UHIE) [16].UBGI offers opportunities to significantly improve urban public services [17][18][19][20], facilitate social connections, and enhance the quality of public spaces [21,22]. UBGI can boost vitality and increase surrounding land values. It can, thus, be employed as a catalyst for redevelopment [23][24][25]. Furthermore, the potential benefits of UBGI in terms of aesthetics and spatial definition could also be effectively deployed to preserve and reshape the identity of a site or even a city, especially in the case of key locations such as municipal centers or historic areas [26,27].Due to UBGI's various benefits, investigations into the integral planning and management of UBGI are currently being carried out all over the world. As a result, a series of interchangeable terms have emerged, including water-sensitive urban design (WSUD) and sustainable urban drainage systems (SUDS) in the UK and Australia, as well as low-impact development (LID) [28] and stormwater best management practices (SBMP) [29] in the United States.However, in practice, formulating an integral plan for UBGI can be difficult. Integrating blue and green systems, whose different features would probably have been organized in isolation in the past, is challenging. Adapting UBGI to the built environment is itself a task full of complexity and uncertainty [8,30]. For example, in t...
