| 水循环与碳循环是陆地生态系统与大气之间物质与能量交换的核心，构建流域水碳耦合模型是量化研究变化环境下水资源与生态系统响应的重要手段。本研究基于WaSSI生态水文模型，改进并发展了其中的蒸散发、积融雪、汇流、固碳等模块，针对中国地区特点，构建了0.1°×0.1°网格分布式中国水碳平衡模拟模型（WaSSI-CN），模型结构简洁、灵活易用，可快速实现流域生态水文过程与水碳平衡关键要素的高分辨率模拟，为解析我国流域水碳平衡演化规律与评估产水、固碳等生态系统服务功能提供科学基础工具。 |
| 英文摘要: |
| Water cycle and carbon cycle are fundamental processes that involve the exchanges of material and energy between terrestrial ecosystems and the atmosphere. Watershed-scale water-carbon coupling models are critical for quantitatively investigating the responses of water resources and ecosystems to dynamic environmental changes. In this study，we have enhanced and expanded modules within the WaSSI ecohydrological model，with a specific focus on evapotranspiration，snowmelt，runoff，and carbon sequestration. The distributed water-carbon balance simulation model has been developed for China（WaSSI-CN）at a spatial resolution of 0.1°×0.1°. It offers an adaptable tool for rapid and high-resolution simulations of ecohydrological processes and key components of the terrestrial water-carbon balance. It can be used to quantitatively analyze the spatiotemporal dynamics of water-carbon balance and evaluate critical ecosystem services such as water provisioning and carbon sequestration in China. |
