摘要
揭示生态系统服务(ESs)与基本公共服务(BPSs)的权衡关系以及城市化对其影响特征对于促进可持续发展具有重要意义。以成渝地区双城经济圈为例,基于可持续发展目标(SDGs)定量评价2011—2021年ESs与BPSs时空演变特征,利用均方根偏差(RMSD)分析二者的权衡关系,通过地理加权回归(GWR)模型揭示城市化对其权衡关系的影响强度与方向。结果表明:(1)各项ESs均有不同程度的提升,总ESs空间分布失衡,呈现四周高、中间低的包围式结构;(2)各项BPSs都有所增长,总BPSs高值区始终集中在成都主城区与重庆渝中区,呈现双核结构;(3)ESs-BPSs权衡强度上升,呈现外围高、中部低且成都主城区、重庆渝中区高值明显的空间特征,BPSs与ESs失衡现象持续存在;(4)在影响强度上,人口城市化的提升对ESs-BPSs权衡影响最为显著,在影响方向上,经济城市化、人口城市化以及综合城市化的提高对ESs-BPSs权衡表现出缓解作用,土地城市化的提高则表现出加剧作用。研究结果可为政府制定可持续发展政策提供参考。
Unveiling the trade-off relationship between ecosystem services(ESs)and basic public services(BPSs)and the characteristics of the impact of urbanization on them is of great significance for promoting sustainable development.Taking the Chengdu-Chongqing Economic Circle(CCEC)as an example,the spatio-temporal changes of ESs and BPSs from 2011 to 2021 were quantitatively evaluated based on the Sustainable Development Goals(SDGs),and the tradeoff relationship between the two was analyzed using the root mean square deviation(RMSD),and the intensity and direction of the impact of urbanization on their trade-off relationship was revealed through the Geographically Weighted Regression(GWR)model.The results showed that:(1)Each ESs improved to varying degrees,and the spatial distribution of total ESs was unbalanced,showing a surrounding structure with high values around and low values in the middle;(2)All BPSs increased,and the high-value areas of total BPSs were always concentrated in the main urban area of Chengdu and Chongqing Yuzhong District,showing a dual-core structure;(3)The trade-off intensity between ESs and BPSs increased,showing a spatial feature of high values on the periphery and low values in the middle,with obvious high values in the main urban area of Chengdu and Chongqing Yuzhong District,and the imbalance between BPSs and ESs persist;(4)In terms of impact intensity,the improvement of population urbanization had the most significant impact on the ESs-BPSs trade-offs.In terms of impact direction,the improvement of economic urbanization,population urbanization,and comprehensive urbanization showed a mitigating effect on the ESs-BPSs trade-off,while the improvement of land urbanization showed an aggravating effect.The research results can provide reference for the government to formulate sustainable development policies.
