树干横截面面积年增长量的垂直分布研究进展

Research Progress in Vertical Distribution of Annual Increase of Trunk Cross-sectional Area

树干横截面面积年增长量(RAI)的垂直分布研究是揭示干形变化机理,了解树干水分传输及机械支持功能变异和机制的基础。笔者就RAI垂直分布的观测方法、理论和实际模式、模拟方法、主要影响因子、与代表性观测位置的关系、与VAI的关系、与单木叶生物量的关系等方面的研究进展进行了总结分析,并对其未来的研究方向和重点内容进行了展望。

Research on the vertical distribution of annual increase of trunk cross-section area increment(RAI)was the basis for revealing the mechanism of changes in trunk form and understanding function variation in the water transport and mechanical support of the trunk.The research progress in vertical distribution of RAI was summarized and analyzed from the aspects such as the observation method,theory and actual patterns,simulation method,main influencing factors,the relationship with representative measuring position,the relationship with VAI,the relationship with leaf biomass of single tree.The future research directions and key research contents of RAI vertical distribution were prospected.
