| 摘 要： | 为了探讨横断山区同倍杂交种高山松与其亲本种云南松的地理隔离机制，采用实际的路线踏查方法，调查了高山松和云南松群体的地理分布情况和开花物候特征，并基于7个气象因子进行了聚类分析。调查研究表明高山松和云南松群体分布在不同的地貌类型中，以云南中甸为临界区，沿着金沙江河谷向北分布高山松，向南分布云南松。云南松的开花物候日期明显早于高山松，聚类分析表明两个物种分别聚为一支。在地质历史过程中，高大山系的形成以及海拔的升高将高山松和云南松从地理上隔离开来，两物种的适生区的气象因子的差异造成花期不遇，从而阻碍了两个物种问的基因交流，进而隔离开来。

| Abstract: | In order to elucidate the geographic isolation mechanisms between the homoploid hybrid Pinus densata and its parental Pinus yunnanensis in the Hengduan Mountains, we investigated the geographical distribution and flowering phenology of the populations of P.densata and P.yunnanensis by the actual route survey. The cluster analysis was based on seven meteorological factors. The resutls showed that P.densata and P.yunnanensis were distributed in different landscapes, and Zhongdian which located in Yunnan Provi... |
