摘　　要：以草牧场防护林的主要组成树种—樟子松、兴安落叶松和各品种杨树作为研究对象,采用设置标准地的方法,重点调查了樟子松、兴安落叶松和中东杨在不同土壤类型上以及其他主要杨树品种与樟子松在相同土壤类型上的生长状况。通过对它们生长指标的直观比较和分析,提出了樟子松、兴安落叶松、中东杨和其他各品种杨树适生的土壤类型,为该地区成功营造草牧场防护林提供基础数据和理论依据。Main tree species of shelterbelts on the pastureland in western part ot northeastern China-Pinus syivistris var. mongolica Litv. Larix gmelinii Rupr. and other Poplus spp. varieties were studied. Their growth condition in different types of soils, and that of Pinus sylvistris var. mongolica Litv. and other poplar varieties in the same type of soil were emphatically stated above were investigated through establishing permanent sample plots. Suitable types of soil for tree species as forward by the method of intuitive comparison and analysis on their growth index. This study provided the basic data and theoretical proof for successful establishment of Sheherbehs on Pastureland in this region.
