Abstract

In the face of accelerating urbanization, Urban Green Spaces (UGS) have become vital for sustaining urban ecosystems and the health and well-being of urban residents. This study offers a comprehensive analysis of the growth rate of urban green space (GRUGS) across various regions in China over a two-decade period, highlighting the interplay between urban development, population dynamics, and ecological sustainability. The research meticulously examines the impacts of urban built-up area expansion, population growth, and air pollution on GRUGS. It categorizes 291 Chinese cities into 15 urban agglomerations and utilizes data on urban built-up areas, population, and PM2.5 levels from 2000 to 2020. The findings reveal a mixed picture: while some regions demonstrate a robust commitment to integrating green spaces within urban growth, evident in high GRUGS values, others struggle to preserve green spaces amidst rapid urban expansion and population surges. This study underscores the necessity of tailored urban planning strategies that are region-specific and the ongoing need for innovation in urban development to achieve ecological sustainability. The insights garnered are invaluable for policymakers and urban planners, stressing the indispensable role of green spaces in enhancing urban life quality and securing sustainable urban environments.

2000 至 2020 年中国城市绿化增长受遗产效应影响
面对不断加速的城市化进程,城市绿地(UGS)对于维持城市生态系统和城市居民的健康与福祉至关重要。本研究全面分析了二十年来中国各地区城市绿地(GRUGS)的增长率,突出强调了城市发展、人口动态和生态可持续性之间的相互作用。研究细致考察了城市建成区扩张、人口增长和空气污染对城市绿地的影响。研究将中国 291 个城市划分为 15 个城市群,并利用 2000 年至 2020 年的城市建成区、人口和 PM2.5 水平数据进行分析。研究结果揭示了一个喜忧参半的局面:一些地区表现出将绿地融入城市发展的坚定决心,GRUGS 的高值就是明证;而另一些地区则在城市快速扩张和人口激增的情况下努力保护绿地。这项研究强调了根据地区特点制定有针对性的城市规划战略的必要性,以及在城市发展中不断创新以实现生态可持续性的必要性。所获得的见解对决策者和城市规划者来说非常宝贵,强调了绿地在提高城市生活质量和确保可持续城市环境方面不可或缺的作用。

期刊介绍: Urban Ecosystems is an international journal devoted to scientific investigations of urban environments and the relationships between socioeconomic and ecological structures and processes in urban environments. The scope of the journal is broad, including interactions between urban ecosystems and associated suburban and rural environments. Contributions may span a range of specific subject areas as they may apply to urban environments: biodiversity, biogeochemistry, conservation biology, wildlife and fisheries management, ecosystem ecology, ecosystem services, environmental chemistry, hydrology, landscape architecture, meteorology and climate, policy, population biology, social and human ecology, soil science, and urban planning.
