国际树轮水文学研究进展

树木年代学丰富的内容和知识体系, 成熟的研究方法, 为区域尺度上研究水文变化提供了精确的方法. 基于树轮重建水文, 认识过去长期自然水文变化格局, 合理规划与管理水资源的价值, 使树轮研究在水文气候变化研究中愈来愈受到人们的广泛重视.在短短的几十年里, 树轮水文学取得了日新月异的进展, 成为继树轮气候学之后又一快速发展的应用学科.在理解树轮水文学科学概念与内涵的基础上, 介绍了基于树轮重建水文的主要手段与方法, 从重建径流、重建极端水文事件、重建降水及重建湖泊沼泽水位等4个方面综述了国际树轮水文学的研究内容与进展, 并简要的概述了其未来发展趋势.

Advances in Dendrohydrology around the World

A rich content and system of knowledge, mature research methods in dendrohydrology provide accurate methods for studying long-term hydrologic variability at regional scale. It is valuable in reconstructing hydrology based on tree ring to discern patterns of past long-term nature hydrologic variability and to valid plan and administer water resources. People in the course of hydrology-climate change researches have paid more and more attention to dendrohydrology. In the past several decades, considerable progress has been made in dendrohydrological studies in the world. It turns into another main applied subject following dendroclimatology. Based on scientific understanding to its concept and connotation, the methodology of hydrologic reconstruction with tree ring is introduced. The paper reviews the content and advances from four aspects: streamflow reconstruction, reconstruction of dry and flood, reconstruction precipitation and other reconstructions such as water level of lakes and bogs and so on. The development trend in this field is also briefly summarized.
