可持续发展目标(Sustainable Development Goals,SDGs)的实现往往会因为生态保护或人类福祉之间可能存在的权衡关系而受到阻碍。将生态系统服务(Ecosystem services,ESs)纳入到可持续发展目标的决策中能够避免各方利益的冲突,促进SDGs的实现。然而,在生态环境脆弱的山区,ESs对SDGs的贡献分析仍然不足。以川西地区为研究区,对2000—2020年11个可持续发展目标进行了量化,利用生态系统服务和权衡的综合评估(Integrated Valuation of Ecosystem Services and Tradeoffs,InVEST)模型和定量指标法估算了碳固存、土壤保持和食物生产三种重要生态系统服务,并使用空间面板数据模型研究ESs对SDGs的影响及其空间溢出效应。结果表明:(1)可持续发展目标水平整体提升,但SDG1(无贫穷)和SDG3(良好健康和人类福祉)表现较差,分值低于5分。从空间上看,与环境相关的SDGs在川西北高原表现更好,与社会经济相关的SDGs在川西东部和川西南山地地区表现更好。(2)川西地区碳固存和食物生产服务呈现线性增长趋势,土壤保持服务呈现波动增长趋势,分别增长了0.23×10~8t、8.93×10~5t和1.23×10~8t。(3)与土壤保持和食物生产相比,碳固存对SDGs表现出更强烈的直接影响和空间溢出效应。其中县域碳固存对本县域和邻近县域的SDG11(可持续城市和社区)和SDG1具有显著的促进作用,对SDG2(零饥饿)呈现显著负向影响。研究结果可为区域联合管理提供科学依据,推动可持续发展目标的实现。

Since the inception of the United Nations’2030 Agenda,commonly known as the Sustainable Development Goals(SDGs),in2015,we have now reached the halfway point in this ambitious global ***,progress towards the SDGs has veered significantly off track,partly due to key global changes such as the COVID-19 pandemic[1],necessitating an immediate acceleration of efforts[2,3](as shown in Fig.1a).While the SDGs represent a global consensus,the substantial work required to achieve them needs to be carried out at the national,regional,and local scales,where concrete and feasible actions must be taken to accelerate the SDG achievement within the 2030 *** underscores the urgent need for science-driven transformations to fully achieve SDGs in the remaining seven ***,the information necessary to support these transformations is still lacking,highlighting the pressing requirement for corresponding research *** endeavors should encompass gaining a comprehensive understanding of the current status of SDG implementations across varying scales,identifying the bottlenecks that hinder progress,setting priorities for implementation,and exploring pathways to expedite progress.
