Abstract
Urban green space (UGS) equity is crucial for sustainable urban development, social harmony, and stability. Given the escalating environmental justice crisis in megacity UGS, ensuring spatial justice and social equity in these areas is vital for sustainable development. This study analyzes the equity of UGS in megacity by assessing both spatial equity from the supply perspective and social equity from the demand perspective while exploring key factors driving this equity. This study found that: 1) The green Gini coefficient in Tianjin's central city, stands at 0.7787, indicating significant spatial inequity, with small UGS exhibiting the highest, followed by medium and large spaces. 2) There is a varying perception of UGS equity across different socioeconomic groups, most pronounced in the center urban area, then in the encircling urban area and remote urban area, indicating a gradual diffusion of green equity from the city center outward. 3) Key external factors influencing UGS equity include economic development, population density, traffic patterns, and local environmental quality, while internal factors like accessibility and size also play a role in spatial equity. Thus, enhancing UGS equity in megacities requires not only top-down supply interventions but also bottom-up demand feedback mechanisms.
期刊介绍:
The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
