| 以安徽省沿长江城市为研究对象，运用InVEST模型，定量评估分析1990-2022年水源涵养、水土保持、生境质量、碳储量四项关键生态系统服务时空变化特征，根据评估结果对生态系统服务进行分区，并对生态系统服务进行权衡协同关系分析。研究结果表明：1990-2022年间，安徽省沿长江城市4种生态系统服务下降趋势有所不同，其中水源涵养、土壤保持呈先降后增再降的趋势；生境质量、碳储量呈持续下降趋势。安徽省沿长江城市生态系统服务分区空间分异明显，呈现出“西北部好、东北部差”的分布特征，数值呈现“下降-升高-下降”趋势，且下降速度逐渐加快。安徽省沿长江城市整体权衡协同关系全部为正值，表现为协同关系主导，且协同关系整体水平较高，但呈现出持续衰减的趋势，且衰减速度逐渐加快。 |

| Taking the cities along the Yangtze River in Anhui Province as the research object, the InVEST model was used to quantitatively evaluate and analyze the temporal and spatial variation characteristics of four key ecosystem services of water conservation, soil and water conservation, habitat quality and carbon storage from 1990 to 2022. The ecosystem services were divided according to the evaluation results, and the trade-offs and synergies of ecosystem services were analyzed. The results showed that : from 1990 to 2022, the downward trends of four ecosystem services in cities along the Yangtze River in Anhui Province were different. Among them, water conservation and soil conservation showed a trend of decreasing first, then increasing and then decreasing. Habitat quality and carbon storage showed a continuous downward trend. The spatial differentiation of urban ecosystem service zoning along the Yangtze River in Anhui Province is obvious, showing the distribution characteristics of ' good in the northwest and poor in the northeast '. The value shows a trend of ' decline-rise-decline ', and the decline rate is gradually accelerating. The overall trade-off synergy relationship of cities along the Yangtze River in Anhui Province is all positive, which is dominated by synergy relationship, and the overall level of synergy relationship is high, but it shows a trend of continuous attenuation, and the attenuation speed is gradually accelerated. |
