摘要
树木的生长与立地环境密切相关并受气候变化的影响,树木年轮宽度作为反映气候与环境变化的一个重要参数,已被广大生态学家所重视并应用。本文综述了树木年轮宽度与温度(当年初春温度、前一年的夏季高温和冬季低温)、降水(生长季的降水和生长季前的降水)、太阳辐射、CO2浓度等气候因子的关系及其在古气候环境研究、环境预测等领域中的应用,并对该研究的量测方法和数据处理分析方法的进展作了概述。针对我国树木年轮宽度研究的现状,提出了扩大取样范围、拓宽研究领域、改善取样和分析方法、建立完善的树轮年表体系、加强与国外树轮研究工作者的信息交流等建议,为我国树木年轮宽度研究的进一步发展提供了理论参考。
The growth of trees is closely relative to the environment and is influenced by the climatic changes. As an important parameter to show the climatic and environment changes, tree-ring width has been paid more attention and applied by lots of ecologists. In this paper, the relationships between tree-ring width and the climatic factors such as temperature (early spring temperature in days, summer high temperature and winter low temperature in the year before last), precipitation (precipitation in and before growing season), solar radiation and CO_2 concentration were reviewed. The application of tree-ring width in the investigation of paleo-climate and forecasting of environment and the trend of the future development were discussed. The development of measure and data analysis methods was summarized. According to the study status of tree-ring width in our country, the suggestions of expanding sample ranges, extending study fields, improving sample and analysis methods, establishing perfect system of tree-ring age and enhancing information communication with foreign scholars were put forward for the further development of tree-ring width study.
