Abstract
Urban parks are critical for sustainable urban development. They are of theoretical and practical significance for analyzing the visual landscape of recreational spaces from the perspective of the elderly. This analysis can be used for exploring new methods for optimizing recreational space layouts to improve the physical and mental health of the elderly in parks, thus realizing the sustainable development of urban society. Taking Ziyang Park in Shangrao Central District of Jiangxi Province, China, as an example, starting from the visual characteristics of the elderly, this study quantitatively calculated the landscape viewability, total view ratio, and water view ratio for the elderly in each recreational space using Python Scripting for ArcGIS. We briefly express the elderly suitability of the visual landscape for each recreational space through a weighted synthesis of the calculation results. Our findings show that, in Ziyang Park, the elderly suitability of the visual landscape for recreational spaces is not only low overall, but also gradually decreases from the interior to the exterior of this park. Moreover, this spatial distribution may be caused by the location of zoning, surface elevation, and road slopes, as well as the individual characteristics of each recreational space. Finally, we discuss the requirements of the elderly for some geographical factors, along with the feasibility of using ArcGIS 3-D analysis to optimize the layout of the park recreational space, with the aim of providing a new research perspective and an effective reference method for designing layouts of such spaces that are favorable for the elderly to better guarantee the sustainable development of urban society.
Highlights
The world’s population is aging [1]
Faced with the severe trend in population aging, an increasing number of scholars have begun to focus on the elderly suitability of parks and have aimed to improve this suitability to ameliorate the health and living conditions of the elderly, promoting the sustainable development of urban society [4,5]
Based on the concept and evaluation index system of the elderly suitability of the visual landscape of park recreational spaces, this study evaluates and analyzes the elderly suitability of the visual landscape of the recreational spaces in Ziyang Park using Python Scripting for ArcGIS; we discuss the feasibility of optimizing the layout of these spaces using ArcGIS 3-D analysis, combined with the requirements of the elderly for some terrain factors
Summary
The world’s population is aging [1]. By 2030, the proportion of people over 60 in the United States, Japan, and the United Kingdom will increase to 26.1, 27.8, and 37.3%, respectively [2]. Parks are the most commonly visited public green spaces for the elderly in the city. They play an indispensable role in maintaining the physical and mental health of the elderly and promoting social interaction. Faced with the severe trend in population aging, an increasing number of scholars have begun to focus on the elderly suitability of parks ( referred to as “aging-suitability” [4], which essentially reflects the suitability of parks for the elderly) and have aimed to improve this suitability to ameliorate the health and living conditions of the elderly, promoting the sustainable development of urban society [4,5]
