摘　　要：在全球气候变化和水资源危机背景下,人类对土地、森林和水资源的适应性管理需求推动了生态系统水、碳耦合与制约关系的研究.在多时空尺度上研究水、碳耦合关系、以及探讨全球变化下生态系统水、碳平衡及其相互响应机制是现阶段的研究热点.本文在综述不同尺度水、碳耦合关系的基础上,探讨了其中关键过程与参数的涵义和测算方法,分析了大尺度上基于遥感技术的蒸散发模型的构建及其对水碳耦合研究的重要性,最后展望了多源数据同化技术等在未来气候变化背景下水碳耦合模拟中的应用.The increasing demand of adaptive management of land, forest, and water resources un- der the background of global change and water resources crisis has promoted the comprehensive study of coupling ecosystem water and carbon cycles and their restrictive relations. To construct the water-carbon coupling model and to approach the ecosystem water-carbon balance and its interactive response mechanisms under climate change at multiple spatiotemporal scales is nowadays a major concern. After reviewing the coupling relationships of water and carbon at various scales, this paper explored the implications and estimation methods of the key processes and related parameters of water-carbon coupling, the construction of evapotranspiration model at large scale based on RS, and the importance of this model in water-carbon coupling researches. The applications of assimilative multivariate data in water-carbon coupling researches under future climate change scenarios were also prospected.
