摘 要:调查了内蒙古东南部山地主要造林树种华北落叶松、兴安落叶松、油松、樟子松人工林立地条件和林分生长情况,依据立地因子(海拔高度、土壤类型、土层厚度、坡向、坡度)和林分因子(优势木高、树龄),应用统计学方法划分了造林立地类型,用样地资料拟合了4个针叶树种的生长模型,分别编制了适宜该区的立地指数表,并对该区针叶树造林立地质量做出了评价。研究表明,内蒙古东南部山地针叶树人工林中57.11%的立地质量处于中等水平,近30%立地质量较差,仅有13.22%的林分生产力水平处于优等水平。Site conditions and growing situation of Larix principis - rupprechtii Mayr, Larix gmelinii (Rupr.)Rupr. , Pinus tabulaeformis Carr. and Pinus sylvestris var. mongolica Litv. plantation have been investigated in mountainous area in southeast of Inner Mongolia. According to site factors ( elevation, soil type, soil depth, slope direction and gradient) and stand factors ( dominant height, tree age) , site types of afforestation have been divided by use of statistics method, growing model of four kinds of needle - leaved trees have been fitted, and the suitable site index tables have been compiled separately. The site quality of needle -leaved trees has been evaluated. The researches show that in mountainous area in southeast of Inner Mongolia, 57.11 percent of site quality of needle - leaved plantation is at middle level, with about 30 percent at low level and only 13.22 percent at fine level.
