摘　　要：解析生态系统服务间权衡与协同的时空特征,是可持续生态系统服务管理的基础和前提。以河南省沿黄8个地市为研究区域,采用InVEST模型和市场价值法,评估了2011年和2021年碳储量、生境质量、产水量和食物供给4项生态系统服务,并利用Spearman相关系数分析了各项生态系统服务间的权衡与协同关系。结果表明:①2011年与2021年生境质量、碳储量和食物供给服务的空间分布变化不大,生境质量和碳储量服务的高值区主要位于太行山地、豫西山地生态区以及黄河沿岸,低值区集中于各市辖区;食物供给服务高值区集中于平原区。②与2011年相比,2021年各项生态系统服务均有所变化,平均生境质量下降了0.011,碳储量减少了236.19万t,产水量增加了54.21亿m^(3),食物供给服务价值增加了1218.82亿元。③从权衡关系看,碳储量、生境质量、产水量和食物供给4项生态服务两两之间均为显著相关关系,其中食物供给、生境质量和碳储量之间为互相增益的协同关系;产水量与生境质量、碳储量、食物供给服务表现为相关系数不稳定的协同关系。研究结果可为探讨快速城市化地区生态系统服务间的权衡协同关系及其优化提供参考依据。Understanding spatiotemporal patterns of ecosystem service(ES)trade-offs and synergies is critical for sustainable landscape management in rapidly urbanizing regions.This study evaluates four key ES(carbon storage,habitat quality,water yield,and food supply)across eight Yellow River-bordering cities in Henan Province(between 2011 and 2021)using the In-VEST model and market valuation.The Spearson correlation coefficient was used to analyze the balance and synergy between the various ecosystem services.The results showed that:①Spatial distributions of habitat quality,carbon storage,and food supply remained stable,with ecological hotspots persisting in the Taihang Mountains,western Henan highlands,and riparian zones,while urban cores and plains exhibited ES deficits.②Decadal changes show trade-off dynamics:habitat quality(decline:Δ=-0.011)and carbon storage(-2.36 million tons)decreased despite gains in water yield(+5.42 billion m^(3))and food supply(+CNY 121.88 billion).③Synergies dominated ES relationships:strong positive correlations linked food supply with carbon storage/habitat quality,whereas water yield exhibited unstable synergies with other services.These findings highlight the need for spatially differentiated strategies to mitigate urbanization-driven ES trade-offs in fluvial urban corridors.
