本文以毛乌素沙地、红花尔基沙地、那日苏台林场(山地)等三个不同地区樟子松为依据,在各地区林木密度相差不大的具有代表性的林分内各设一个标准地,进行每木检测,选择标准木进行树干解析。再通过比较以上三个地区樟子松树高、胸径、材积生长等生长特性,初步探讨不同地区樟子松的生长规律,进一步掌握樟子松在沙地和山地的生物学特性及生态适应性,为我区主要造林树种选种提供科学依据。不同地区樟子松生长特性的研究结果表明,樟子松在毛乌素沙地东北边缘沙丘引种栽植,适应性强,无论是树高、胸径还是材积生长都比其原产地-红花尔基沙地好。虽然那日苏台林场引种樟子松的树高、胸径还是材积生长都不如红花尔基沙地好,但其生长良好。
Based on Pinus sylvestris var. Mongolica in three different regions such as Mu Us sandy land, Honghuaerji sandy land, Nati ssu Tai forest farm (mountainous area), and so on, A standard, for each wood test, select the standard wood trunk analysis. Then by comparing the growth characteristics of Pinus sylvestris var.Mongolica, DBH and volume growth in the above three regions, the growth patterns of Pinus sylvestris var.Mongolica were discussed initially to further understand the biological characteristics and ecological adaptability of Pinus sylvestris var.mongolica in sandy and mountainous areas, Provide the scientific basis for the selection of the main afforestation tree species in our district. The study on the growth characteristics of Pinus sylvestris var. Mongolica in different areas showed that Pinus sylvestris var. Mongolica was introduced and planted in the northeastern edge of the Mu Us Sandland, and its adaptability is higher than that of its native Hongheerji sandy land, regardless of tree height, DBH or volume growth it is good. Although the introduction of Taiwan’s Su-t’Tai-t’ien Pinus sylvestris tree height, DBH or volume growth are not as good as Honghuaerji sand, but its growth is good.
