新疆山地天然林中,成林树种主要为雪岭云杉与西伯利亚落叶松。在天山中西部南北坡为大面积的云杉纯林,而天山东端和阿尔泰山的绝大部分是西伯利亚落叶松。这种松是新疆建立大片用材林基地的树种之一。鉴于此,对于解放前后各类型的采伐迹地及其更新隋况,进行了调查,以及对其合理采伐方式与更新问题提供参考。 Among the natural mountain forests in Xinjiang, the main species of forest are the snowy spruce and Siberian larch. The north-south slope in central and western Tianshan is a large area of ​​spruce pure forest, while the eastern part of Tianshan Mountains and Altai Mountains are mostly Siberian larch. This kind of pine is one of the tree species for the establishment of large-scale timber forest base in Xinjiang. In view of this, we have conducted surveys on various types of logging sites before and after the liberation and their renewal, and provided references for their reasonable methods of harvesting and updating.
