| 中文摘要 |
| 在可持续发展和生态文明建设背景下，研究流域的生态系统服务的时空演变及其权衡与协同关系，有助于地区社会经济可持续发展和生态环境治理. 利用InVEST模型、Pearson 相关系数等方法，从“空间代替时间”和“时期差异”的视角，分析赣江流域2000~2020年4类生态系统服务的时空演变、权衡与协同关系. 结果表明：①4类生态系统服务的时空格局具有较大的差异，呈现上中下游的显著分段差异. ②“空间代替时间”的视角下，各类生态系统服务的权衡与协同关系在不同的空间中具有一定的稳定性，产水能力在空间分布上与其他生态系统服务呈现显著空间权衡关系，并且该关系呈现减弱趋势. 除产水外的生态系统服务相互之间呈现稳定协同关系. ③“时期差异”视角下，赣江流域不存在稳定的生态系统服务权衡与协同关系，上中下游的生态系统服务权衡与协同呈现显著时间分异. ④采用时空权衡的区域协调策略和适应性的策略，可以发挥生态系统服务协同效应的潜力，需针对赣江上中下游的特殊性，采用因地制宜的国土空间治理方式. 研究结果可以为地区生态系统服务的协同发展提供科学参考. |

| Against the backdrop of sustainable development and ecological civilization construction， studying the spatiotemporal evolution of ecosystem services in river basins and their trade-offs and synergistic relationships contributes to the sustainable social-economic development and ecological environmental governance of regions. Using methods such as the InVEST model and Pearson correlation coefficient， this study analyzes the spatiotemporal evolution， trade-offs， and synergies of four types of ecosystem services in the Ganjiang River Basin from 2000 to 2020， from the perspectives of “substituting time with space” and “period differences”. The results show： ① The spatiotemporal patterns of the four ecosystem services exhibited significant differences， with notable segmental disparities among the upper， middle， and lower reaches. ② From the perspective of “substituting time with space”， the trade-offs and synergies of various ecosystem services maintained certain stability across different spatial contexts. Water yield capacity showed significant spatial trade-offs with other ecosystem services in spatial distribution， and this relationship exhibited a weakening trend. Ecosystem services except for water yield demonstrated stable synergistic relationships with each other. ③ From the perspective of “period differences”， stable trade-offs and synergies of ecosystem services did not exist in the Ganjiang River Basin， and significant temporal differentiation was observed in the trade-offs and synergies of ecosystem services across the upper， middle， and lower reaches. ④ Implementing regional coordination strategies based on spatiotemporal trade-offs and adaptive measures can unleash the potential for synergistic effects of ecosystem services. It is necessary to adopt land spatial governance approaches tailored to the specific conditions of the upper， middle， and lower reaches of the Ganjiang River Basin. The research results provide a scientific reference for the synergistic development of regional ecosystem services. |
