林木尺度水分利用测算方法与研究进展

树木水分利用的研究总体上可分为三个尺度, 即叶片、林木和林分尺度. 近年来, 林木水分利用的定量研究显得日益重要, 森林生理学和森林水文学的发展以及应用都与林木水分利用的定量研究密不可分. 对国内外近年来林木尺度水分利用研究的方法、 研究进展及存在的问题进行了详细的阐述, 提出了今后林木水分利用定量研究需开展的重点工作, 以期促进林木水分利用定量研究的进一步发展.

Progress in the Measurement and Research of Whole-Tree Water Use

As a whole, studying the tree water use may be divided into three scales, i.e., leaf, whole-tree and stand scale, respectively. In the recent years, estimating the water use by whole-tree is becoming increasingly important in forest sciences, and the development and the application of tree physiology and forest hydrology are indispensable to the quantitative study of whole-tree water use. In this paper, aiming at the quantitative study of the forest water use at forest scale, research methods, research progress and the questions in the process of research about quantitative whole-tree water use in the recent 20 years are reviewed, and the works which must be done in the future are also broached. It is expected to promote the further development of the quantitative study of the forest water use, because the quantitative whole-tree water use and tree physiology are able to study synchronously in the future.
