云南松是我国西南地区荒山造林先锋树种和主要的用材树种,但当前云南松林分的衰退问题已经日益严重,2009年至今在云南地区的连续大旱更是导致了云南松出现成片死亡的现象。基于此,从群落结构及其演替趋势、遗传改良、生长生理响应特征等方面综述了云南松近年来的研究进展,针对云南松面对连年大旱的现实困难,提出了可能的对策与未来的研究展望。建议采用生理生态学方法,重点研究云南松纯林与混交林的碳收支进程对连续干旱逆境气候的响应机制,可以为合理改造云南地区广泛分布的云南松低产林分、提高云南松的林分质量和生态效益提供理论与现实依据。
Pinus yunnanensis Franch.is the afforestation pioneer and main commercial tree species in southwest region of China.However,the recession problem of Pinus yunnanensis Franch.forests has been increasingly serious,the continuous drought in Yunnan Province from 2009 till now even lead to the massive death of Pinus yunnanensis Franch.Consequently,the research advance of Pinus yunnanensis Franch was summarized including community structure and succession tendency,genetic improvement and physiological response characteristics of growth,etc..In recent years,the possible solutions and future research prospects were raised based on the realistic difficulties of Pinus yunnanensis Franch.forests.We suggested that the physiological and ecological methods should be used to study the responding mechanism of carbon budget process in Pinus yunnanensis Franch.pure and mixed forests against the continuous drought climate.These results could provide the theoretical and realistic foundations for the reasonable transformation of low yield stands and the improvement of both stand qualities and ecological benefits of Pinus yunnanensis Franch.which widely distributed in Yunnan Province.
