Abstract
Based on the trend of global aging, people are paying more and more attention to the health of the elderly and the improvement of green open spaces. However, few studies have focused on strategies to improve green spaces in response to this trend. Especially, with the outbreak of COVID-19, an urgent need to develop a sustainable system strategy to improve the health of the elderly in residential communities in old districts has emerged. Traditional improvement strategies based on current situation evaluation often focus on the most prominent practical problems. Therefore, the objective of this study was to provide theoretical research and practical improvement strategies for green open spaces in old downtown residential communities to improve the health and well-being of the elderly. In response to this problem, this research proposes an alternative method based on causality (FDM-DANP-mV model), by extracting 23 green open space elements that affect the health of the elderly and dividing them into three dimensions, to form a preliminary evaluation framework. On this basis, the more effective and feasible standard elements are screened out, and the influence relationship behind the elements is clarified. Then, the sustainable development strategy is systematically discussed in three practical cases. This allows for the analysis of the present situation to not only identify the current significant problems but also to capture the source of the influence behind the real problems based on the clarification of the dominant influence relationship. The actual value of this study is to provide a key design decision basis for the improvement of the green open spaces in old downtown residential communities, aiming at avoiding waste to the greatest extent under the premise of limited resources and gradually promoting the improvement of the urban built environment to promote the health and well-being of the elderly.
Highlights
With the aging of the global population, the World Health Organization (WHO) has put forward a policy of “healthy aging” [1], with “providing the aged with safe, inclusive and barrier-free public spaces” [2] as the goal of global aging health strategy and action
How to reduce the dissemination of the virus and restore economic growth through optimal urban planning and architectural design has become an urgent topic in the post-epidemic age [6]
E structure of the rest of this paper is as follows: In Section 2, relevant elements are summarized and the research evaluation framework is initially constructed through a review of key previous studies of outdoor activities, connecting with nature, and social interaction; in Section 3, the methods and steps used in this research are introduced in detail; in Section 4, Fuzzy Delphi Method (FDM) is used to screen the effectiveness of the criteria, DANP is used to clarify the influence relation between and weights of the evaluation criteria, and the evaluation criteria are discussed with regard to three real cases in combination with performance evaluation and improvement based on VIKOR; Section 5 discusses the contributions and limitations of this research and suggests future research directions
Summary
Received 29 January 2021; Revised 9 April 2021; Accepted 27 April 2021; Published 14 June 2021. Erefore, the objective of this study was to provide theoretical research and practical improvement strategies for green open spaces in old downtown residential communities to improve the health and well-being of the elderly. In response to this problem, this research proposes an alternative method based on causality (FDMDANP-mV model), by extracting 23 green open space elements that affect the health of the elderly and dividing them into three dimensions, to form a preliminary evaluation framework. The more effective and feasible standard elements are screened out, and the influence relationship behind the elements is clarified. en, the sustainable development strategy is systematically discussed in three practical cases. is allows for the analysis of the present situation to identify the current significant problems and to capture the source of the influence behind the real problems based on the clarification of the dominant influence relationship. e actual value of this study is to provide a key design decision basis for the improvement of the green open spaces in old downtown residential communities, aiming at avoiding waste to the greatest extent under the premise of limited resources and gradually promoting the improvement of the urban built environment to promote the health and well-being of the elderly
