Exploring Strategies for Improving Green Open Spaces in Old Downtown Residential Communities from the Perspective of Public Health to Enhance the Health and Well-Being of the Aged

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.

A Hybrid Multiple-Attribute Decision-Making Model for Evaluating the Esthetic Expression of Environmental Design Schemes

“…In the data collection operation, with respect to which question form is easier to understand than ANP for experts, DEMATEL only requires pair-wise comparisons of the criterion level by asking questions, such as how much influence criterion A has on criterion B in determining the degree using a scale of 0 (almost no influence) to 4 (highest influence). This scale has been used in other research as well (e.g., Li et al, 2021; Zhang et al, 2021; Zhu et al, 2017). The AHP and DEMATEL questionnaires were distributed to experts who had previously answered the fuzzy Delphi questionnaire, and nine valid questionnaires were collected.…”

“…The FDM used in our study integrated expert opinions by using the “double triangular fuzzy numbers,” as provided by Jeng (2001). Jeng suggested an 11-point scale to assess experts’ level of agreement, and this usage has been continued in subsequent studies (e.g., Li et al, 2021; Zhang et al, 2021).…”

The DEMATEL method explores the interdependent relationship structure and weights for diagnosis-related groups system

“…Thus, the results can assist decision makers in focusing on a small number of core dimensions or criteria from an influence perspective ( 21 ). Researchers have applied this method to various topics such as medical decision-making ( 21 , 22 ), nurse evaluation ( 23 ), education ( 24 , 25 ), design evaluation ( 26 ), and open space planning ( 27 ). The calculation process is presented in our research and is implemented using Excel 2016 software ( 21 – 23 ).…”
