山西是华北落叶松的集中分布区，除主体分布在关帝山、管涔山、五台山和恒山以外，其余在太岳山的绵山、将台，好地方的北来沟、霍山的七里峪及阳高的六棱山等地均为星散分布的残遣小群体，生态条件差异大。对华北落叶松种源幼林（７年生）性状研究表明：种源间存在着显著差异，各性状与产地纬度存在着线性相关关系，在纬向上是单向渐变群的变异趋势。通过聚类分析划分为三个种源类群：晋北种源群和吕梁山脉中段种源群（含一些纬度偏南的残遗小群体，七里峪和好地方种源）生长快；而五台山──管涔山林区的边缘种源群，由于遗传分化，则与此相反；华北落叶松各产地的降水量是其种源变异的主导生态因子。
Shanxi is the concentrated distribution area of Larix principis-rupprechtii. Except for the main distribution in Guandi, Guantie Mountain, Wutai Mountain and Hengshan, the rest are in Mianshan of Taiyue Mountain, Liugang Mountain and other places are scattered scattered groups of small groups, ecological conditions vary greatly. Studies on the traits of Larix principis-rupprechtii seedlings (7-year-old) in North China showed that there was a significant difference between provenances, and there was a linear relationship between the traits and the latitude of the place of production. In the latitudinal direction, the trend of variation was unidirectional. It is divided into three provenance groups by cluster analysis: the provenances of the provenances and Lvliangshan Mountains in the middle of the northern Shanxi Province (including some minor remnant groups of south latitude, Qiliyu and good local provenances) grow fast; and Wutaishan- ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
