摘　　要：高山松(Pinus densata)是云南松(Pinus yunnanensis)和油松(Pinus tabuliformis)的天然同倍体杂交种,是我国西南山区的特有种,具有较高的生态和经济价值。基于系统查阅的相关文献和著作,对高山松自然地理分布格局、物种起源与演化机制、个体生长规律及其环境影响机制进行了综述,阐明了当前需要关注的4点研究内容:(1)物种现有的分布区域和完整的地理分布格局;(2)物种具体的起源地、迁移路线和演化规律;(3)幼树(DBH≤6 cm)生物量估测模型;(4)各器官在不同发育阶段的权衡关系以及对不同生态因子的响应模式和生理学机理。通过对上述内容的深入研究,进一步明确高山松的生态适应策略。Pinus densata initial from natural hybridization between P.yunnanensis and P.tabuliformis.It is an endemic species distributed in the mountainous areas of southwest China,and has great ecological and economic value.We synthesized the natural geographical distribution pattern,species origin and evolution mechanism,individual growth law and environmental impact mechanism of Pinus densata based on 74 literatures published from 1956 to 2021.The results showed that:(1)The distribution area of Pinus densata was centered on southwestern Sichuan,bounded by Jianzha County in Qinghai in the north,Songpan County in Sichuan in the east,Lijiang City in Yunnan in the south,and Sangri County in Tibet in the west,and in western Sichuan and northwestern Yunnan,the elevation distribution range in the south was higher than in the north,and in the west was higher than in the east;(2)Based on molecular biological evidence,it has been inferred that Pinus densata originated in the northwestern Sichuan in the late Miocene,the population differetiation began in the late Pliocene,and migrated westward to the Qinghai-Tibet Plateau,ecological selection was the main driver of speciation,and the uplift of the southeastern Qinghai-Tibet Plateau promoted the species formation;(3)Previous studies have discussed the growth process of height,diameter at breast height,and volume of Pinus densata,and constructed models related to height,diameter at breast height,biomass,and volume,but lack of comprehensive understanding of the differences due to ecological factors in the growth process,such as climate,light,and geographic gradient.And clarified the research contents that need further attention to clarify the ecological adaptation strategy of Pinus densata:(1)Current distribution areas and complete geographic distribution patterns;(2)Specific origin place,migration routes and evolutionary laws;(3)Biomass estimation model for young trees with diameter at breast height lower than 6 cm;(4)The trade-off relationship,response patterns and physiological me
