利用树轮资料重建河流径流量研究进展

利用树轮资料重建河流径流量是树木年轮学研究的一个重要方向。在理解树轮水文学科学概念的基础上,介绍了利用树轮资料重建河流径流量的研究方法,综述了国际上利用树轮资料重建径流量的研究进展。从研究区域、思路与方法、应用领域等3个方面详细综述了中国利用树轮资料重建河流径流量的研究进展,概述了研究存在的问题及未来的展望。结论表明,利用树轮资料重建长尺度的径流序列,能更好地满足江河流域水资源统一管理和规划的需要,能为水资源管理提供丰富的基础资料。

Advances in streamflow reconstruction using tree-ring data

Streamfbw reconstruction based on tree-ring data is an important direction in dendrochronology.In this study, tree-ring reconstructions of streamflow are described on the basis of the principle of dendrohydrology.The methodologies for reconstructing streamflow using tree-ring are introduced, and major advances in the subject are reviewed over the world.We will then focus on the review of nationalprogresses of tree-ring studies emphasizing on aspectsof studying regions, approaches andmethodobgies, and applications.Inadequate aspects in tree-ring researches and prospects of dendrohydrobgy studies are also proposed.It is clear that the tree-ring reconstructed long teffn streamflow series contains valuable info}rnation for better management of water resources and planning in river basins.
