| 中文摘要 |
| 自然保护区是提供生态系统服务和保护生物多样性的有效途径，定量评估生态系统服务及其驱动因素对于自然保护区实施保护管理和规划至关重要. 以赛罕乌拉国家级自然保护区为研究区，量化了2000~2020年产水量、碳固定、生境质量和土壤保持这4种生态系统服务，基于地理探测器和地理加权回归模型（GWR）探索了不同驱动因素对生态系统服务时空格局的影响，并基于自组织映射神经网络（SOM）识别生态系统服务簇，提出管理建议. 结果表明，赛罕乌拉国家级自然保护区各生态系统服务具有空间异质性，2000~2020年产水量与土壤保持显著提升，分别增加了89.8%和126.1%，碳固定提升了5.2%，生境质量基本不变，仅变化了0.7%；降水和土地利用类型是生态系统服务变化的主要驱动因素，双因素交互作用高于单驱动因素的影响；识别出生态核心服务簇、生态过渡服务簇和生态脆弱服务簇这3种生态系统服务簇，并从保护、规划和管理的角度提出了多样化的自然保护区分区管理建议. 研究结果可为赛罕乌拉国家级自然保护区的分区管理与优化提供科学依据. |

| Nature reserves are effective avenues for providing ecosystem services and conserving biodiversity. Quantitative assessments of ecosystem services and their driving factors are crucial for conservation management and planning in nature reserves. Taking Saihanwula National Nature Reserve as the study area， this study quantified four ecosystem services， including water yield， carbon sequestration， habitat quality， and soil conservation， spanning from 2000 to 2020. We explored the influence of different driving factors on the spatio-temporal patterns of ecosystem services by using the Geodetector and Geographically Weighted Regression （GWR） models. Furthermore， we identified ecosystem service clusters based on the Self-Organizing Map （SOM） neural network and proposed management recommendations accordingly. The results showed that each ecosystem service in Saihanwula National Nature Reserve exhibited spatial heterogeneity. From 2000 to 2020， water yield and soil conservation significantly enhanced， increasing by 89.8% and 126.1%； carbon storage enhanced by 5.2%； and habitat quality remained essentially unchanged， with a change of only 0.7%. Precipitation and land use type were the main ecosystem service driving factors， and the combined effects of various driving factors were greater than those of a single factor. We identified three types of ecosystem service bundles， including the ecological core service bundle， ecological transition service bundle， and ecological fragile service bundle. We then proposed diversified zoning management recommendations for nature reserves from the perspectives of conservation， planning， and management. The results of this study can provide a scientific basis for the zoning management and optimization of Saihanwula National Nature Reserve. |
