摘 要
枫香林作为我国亚热带地区重要的森林生态系统，在维持区域生态平衡和提供多种生态服务功能方面具有不可替代的作用。本研究以典型枫香林为对象，基于野外调查与遥感监测数据，结合生态系统服务价值评估模型，系统分析了枫香林的生态服务功能及其空间分布特征，并探讨了其在碳固定、水土保持、空气净化等方面的具体贡献。研究结果表明，枫香林在单位面积上的生态服务价值显著高于其他常见植被类型，特别是在涵养水源和固碳释氧方面表现突出。此外，通过构建保护优先区划模型，明确了关键保护区域及潜在威胁因素。本研究创新性地将多源数据融合应用于生态服务功能定量评估，并提出了针对性的保护对策，为枫香林资源的可持续管理提供了科学依据，同时对类似森林生态系统的保护实践具有重要参考价值。关键词：枫香林; 生态系统服务; 碳固定
Abstract
Liquidambar forests, as an important forest ecosystem in the subtropical regions of China, play an irreplaceable role in maintaining regional ecological balance and providing a variety of ecosystem services. This study takes typical Liquidambar forests as the research ob ject, integrating field survey data and remote sensing monitoring with an ecosystem service value assessment model to systematically analyze the ecological service functions of Liquidambar forests and their spatial distribution characteristics, while exploring their specific contributions to carbon fixation, soil and water conservation, and air purification. The results indicate that the per-unit-area ecological service value of Liquidambar forests is significantly higher than that of other common vegetation types, particularly excelling in water conservation and carbon sequestration-oxygen release. Furthermore, by constructing a priority conservation zoning model, key protection areas and potential threat factors were identified. Innovatively, this study applied multi-source data fusion for quantitative evaluation of ecological service functions and proposed targeted conservation strategies, providing a scientific basis for the sustainable management of Liquidambar forest resources and offering significant reference value for the conservation practices of similar forest ecosystems.
