一种评估植被与气候变化对河川径流影响的方法

An Approach for Separating Relative Effects of Vegetation and Climate Changes on Watershed Hydrology

摘要: 科学评估植被与气候变化对河川径流的影响对造林或采伐规划、流域水资源管理、河流生物多样性及生境保护具有重要作用。它可以帮助我们理解与评估河流形态的变化、泥沙的迁移及水灾与旱灾的规律。文章介绍了国际上一种新的评估方法(Tomer-Schilling framework)，并分析了其计算方法原理。最后，探讨了将该方法引入国内的可行性，以期为我国生态水文学的发展提供参考。

Abstract: Scientific evaluation of vegetation and climate change impact on the runoff of afforestation or cutting planning, management of river basin water resources, rivers of biodiversity and habitat protection plays an important role. It can help us to understand and evaluate the change of river morphology, sediment migration and the laws of flood and drought. This paper introduces the international on a new assessment method (Tomer-Schilling framework), and analyses the calculation method for the principle. Finally, this paper discusses the feasibility of introducing the method of domestic, so as to provide reference for the development of ecological hydrology in China.
