摘　　要：树干直径变化(TDF)对树体水分状况具有高度敏感性,利用TDF指导灌溉已成为近年来国内外研究的热点。文中总结了TDF的基本理论及其相关参数概念,综述了国内外利用TDF诊断树体水分亏缺以指导灌溉的研究概况、指标选择与评估、实践应用等的研究进展,指出目前制约该项研究推广应用的主要问题,并提出研究展望。Trunk diameter fluctuation （TDF） is greatly sensitive to water deficit of trees, so the use of TDF indicator to control irrigation has become a hotspot issue internationally and nationally in the study. This paper concluded the fundamental TDF theory and relevant parameters and concepts, and reviewed general situation of the international and national study on scheduling irrigation with TDF indicating water deficit status of trees, indicators choice and evaluation and their application. Finally, it pointed out the main problems that restrict the application and promotion of the study.
