树木年轮的生长和立地环境密切相关并受多种气候因子的影响.针对国内外树木年轮学的研究成果,综述了树木年轮的宽度、密度、同位素在不同领域的应用,同时系统概述了树木年轮对环境变化的响应,提出应扩宽研究区域和加强阔叶树种的树木年轮学研究、应进一步深入研究全球变化研究中在重建古气候,森林结构和功能动态、群落演替、林业管理及减灾防灾等等方面的应用、在进行树木年轮学研究时应考虑多重因子的共同作用等建议,为我国的树木年轮学研究的进一步发展提供了理论参考.
樹木年輪的生長和立地環境密切相關併受多種氣候因子的影響.針對國內外樹木年輪學的研究成果,綜述瞭樹木年輪的寬度、密度、同位素在不同領域的應用,同時繫統概述瞭樹木年輪對環境變化的響應,提齣應擴寬研究區域和加彊闊葉樹種的樹木年輪學研究、應進一步深入研究全毬變化研究中在重建古氣候,森林結構和功能動態、群落縯替、林業管理及減災防災等等方麵的應用、在進行樹木年輪學研究時應攷慮多重因子的共同作用等建議,為我國的樹木年輪學研究的進一步髮展提供瞭理論參攷.

The growth of tree-ring is affected by the site condition and multi-climatic factors.According to the study status of tree-ring in China and abroad,the applications of width,density and isotope of tree-ring in different fields were reviewed and the responses of tree-ring to environmental changes were systemic introduced in this paper.Then,some suggestions were proposed to provide theoretical basis for further development of tree-ring study that showed as follows:expanding research area,strengthening tree-ring study of broad-leaved species,further studying in application of global changes on reconstructing paleoclimate,structure and function of forest,community succession,forestry management and fire prevention,and considering the interaction of multi-factors during the research of tree-ring.
