摘要

新型城市化(NU)作为城市发展的一个新方向,通过调节生态系统服务(ES)的供需影响可持续发展目标(SDGs)的机制仍有待确定。湖泊周边的城市群人地矛盾突出,社会经济发展与水密切相关。我们选择了中国的环湖城市群作为研究区域。我们研究了 2000 年至 2018 年 NU 和生态系统服务供需比(ESDR)的时空异质性。我们特别关注了可持续发展目标 2(零饥饿)、可持续发展目标 13(气候行动)和可持续发展目标 15(陆地生活)的动态趋势。此外,我们还利用结构方程模型(SEM)揭示了国家大学影响研究区域可持续发展目标实现的直接效应和间接途径,强调了这一机制在湖泊周边各城市群中的差异化表现。研究结果表明,从空间角度看,ESDR 在沿湖、沿河和沿道路网络的城市中心呈特别明显的下降趋势。湖泊周边城市群的 NU 水平总体上升了约 50%。它在地理上呈现出三种主要的空间分布模式:"沿湖扩散"、"均匀分布 "和 "沿河扩散"。NU 直接抑制了可持续发展目标的实现,但间接促进了用于粮食生产和水土保持的退耕还林的改善,从而间接促进了可持续发展目标 2 和可持续发展目标 15 的实现,但对可持续发展目标 13 有抑制作用。通过调节生态减灾,核大国在环鄱阳湖和环洞庭湖城市群实现可持续发展目标方面最为有效,但对环洪泽湖城市群有明显的抑制作用。这项研究为环湖城市群的城市规划转变、陆地生态系统功能恢复和可持续发展目标的实现提供了定量证据。它还为全球环湖城市群的可持续城市建设提供了来自中国的新见解。

Sustainable development of urban agglomerations around lakes in China: Achieving SDGs by regulating Ecosystem Service Supply and Demand through New-type Urbanization
The mechanism through which New-type Urbanization (NU), as a new direction in urban development, influences the Sustainable Development Goals (SDGs) by regulating the Ecosystem Services (ES) supply and demand remains to be determined. It is particularly true in urban agglomerations around lakes, characterized by severe human-land conflicts, where socio-economic development is closely linked to water. We selected China's urban agglomerations around lakes as the study area. We investigated the spatio-temporal heterogeneity of NU and the Ecosystem Service Supply and Demand Ratio (ESDR) from 2000 to 2018. We specifically focused on the dynamic trends of SDG 2 (Zero Hunger), SDG 13 (Climate Action), and SDG 15 (Life on Land). Furthermore, we utilized Structural Equation Modeling (SEM) to reveal the direct effects and indirect pathways through which NU influences the achievement of SDGs in the study area, emphasizing the differentiated performance of this mechanism across various urban agglomerations around Lakes. The results indicated that the ESDR has a particularly evident downward trend in urban centers along lakes, rivers, and road networks in spatial terms. The level of NU in urban agglomerations around lakes has increased by about 50% overall. It geographically exhibits three main spatial distribution patterns: “diffusion along the lake,” “homogeneous distribution,” and “diffusion along the river.” NU directly inhibits the achievement of SDGs but indirectly promotes the improvement of ESDR for food production and soil conservation, thereby indirectly facilitating the achievement of SDG 2 and SDG 15, but has an inhibitory effect on SDG 13. By regulating ESDR, NU is most effective in achieving SDGs in the urban agglomerations around Poyang Lake and Dongting Lake but has a significant inhibitory effect on the urban agglomeration around Hongze Lake. This research provides quantitative evidence for the urban planning shift, terrestrial ecosystem function restoration, and SDGs achievement in urban agglomerations around lakes. It also offers new insights from China for the sustainable urban construction of urban agglomerations around lakes worldwide.

期刊介绍: Habitat International is dedicated to the study of urban and rural human settlements: their planning, design, production and management. Its main focus is on urbanisation in its broadest sense in the developing world. However, increasingly the interrelationships and linkages between cities and towns in the developing and developed worlds are becoming apparent and solutions to the problems that result are urgently required. The economic, social, technological and political systems of the world are intertwined and changes in one region almost always affect other regions.
