不同种源树木径向生长对气候变化响应研究进展

树种群体的地理变异是林木选择育种的基础，研究不同种源径向生长的气候敏感性，对于种子调拨及优良种源的选择具有重要意义。本文综述了不同种源径向生长对气候变化的长期和短期响应，指出同一树种不同种源对气候变化具有不同的响应特征。利用不同种源径向生长对气候变化的响应，可指导未来气候下的种源选择。然而，国内有关同一树种不同种源对气候变化的响应研究仍十分缺乏，树木种源生长对气候变化的响应研究亟待进一步深入开展。采用树轮气候学方法探讨不同树木种源径向生长对气候变化的响应，可有效促进我国森林培育管理，指导选择生产力高、适应性强的种源用于更新造林。

Response of Radial Growth of Different Provenances to Climate Change: A Review

Geographical variation of tree species population is the basis of tree selection and breeding. It is of great significance to study the climate sensitivity of radial growth of different provenances for seed allocation and selection of superior provenances. This paper reviews the long-term and short-term responses of radial growth of different provenances to climate change, suggesting that the response characteristics to climate change vary among different provenances. The response of radial growth of different provenances to climate change can be used to guide provenance selection in the future climate. However, there is still a lack of research on the response of different provenances to climate change, and the response of provenance growth to climate change needs to be further studied. Using the method of dendroclimatology to explore the response of radial growth of different provenances to climate change can effectively promote forest cultivation management and guide the selection of productive and adaptable seed sources for reforestation.
