樟子松(Pinus sylvestris var. mongo lica)原产我国大兴安岭北部山地和呼伦贝尔沙地,具有耐干旱、耐瘠薄等生态学特性,是“三北”地区营造防护林、用材林的主要树种。章古台是最早在沙地上引栽樟子松成功的地区,如今已蔚然成林,充分发挥着防风固沙、改善生态环境之功效。但是近几年出现了樟子松生长量缓慢、生产力水平降低的趋势。本文从气候生态角度出发,对樟子松与气候因 Pinus sylvestris var. Mongo lica originated from mountainous areas of northern Daxinganling and Hulunbeier sandy land, which has the ecological characteristics of drought tolerance and infertility infertility. It is the main tree species for shelterbelts and timber forests in the “Three Norths” region. Zhanggutai was the earliest successful area for planting Pinus sylvestris on sandy land. Now it has become a natural forest, giving full play to the effectiveness of windbreak and sand fixation and ecological improvement. However, in recent years there has been a slow growth of Pinus sylvestris and a decrease in productivity. In this paper, from the perspective of climatic ecology, the Pinus sylvestris var
