| 摘 要： | 农林复合系统是解决当前资源枯竭、农林用地紧张和实现环境保护的一种可持续土壤管理模式。自《京都议定书》签订以来, 农林复合系统因其较高的固碳潜力引起了科学家的广泛关注。深入理解农林复合系统的固碳过程及其对气候变化、环境条件的改变和管理措施的响应, 是准确地预测农林复合系统在全球变化情景下固碳潜力的关键。该文综述了农林复合系统的概念和分类, 探讨了农林复合系统相比单一系统的固碳潜力及固碳机理, 分析了农林复合系统固碳潜力的测定方法和当前面临的挑战, 综述了气候因子、环境条件和人为管理措施对农林复合系统固碳潜力的影响。我国农林复合系统的固碳潜力相比全球其他区域还处于较低水平, 为提高我国农林复合系统的固碳潜力, 未来需要加强以下四个方面的工作: 扩大农林复合系统的分布面积、加强农林复合系统的合理配置和管理、选择适宜的物种组合和优化系统的群体结构。

| Abstract: | Agroforestry is regarded as a sustainable land-use management due to its potential for solving the problem of resource deficiency, improving the livelihood of rural areas and reducing environmental degradation. Agroforestry has attracted considerable scientific attention since the Kyoto Protocol because it has relatively high potential for carbon sequestration. Comprehensively understanding the process of carbon sequestration in agroforestry and its response to climate change, environmental variation and management practices is essential for predicting the carbon sequestration potential of agroforestry under varying climate and land-use patterns. This paper first reviews the concept and classification of agroforestry and then proposes the mechanism of higher carbon sequestration in agroforestry systems compared with monocropping or monoculture pasture systems. Furthermore, the methods used for quantifying the carbon sequestration potential of agroforestry and the present challenges are discussed. Based on the systematic review of previous studies, the effects of climatic factors, environmental conditions and management practices on carbon sequestration potential of agroforestry are illustrated. The carbon sequestration potential of agroforestry is relatively low in China compared with other regions around the world. In order to improve the carbon sequestration potential of agroforestry, future studies should focus on enlarging the area of agroforestry, developing appropriate designs and management of agroforestry, selecting appropriate species composition and optimizing the multi-layer structure of agroforestry. |
