摘　　要：以内蒙古赤峰市短角牛场草牧场防护林的主要组成树种──杨树作为研究对象，普遍调查了杨树在不同立地条件下的生长状况。综合运用直观分析和数理统计相结合的方法，分析了杨树不同品种间的生长差异及其与立地条件之间的相互关系，找出了影响其生长的主要立地因子是土壤容重；并建立了相应的数学模型，提出了杨树适宜的立地条件。The main tree species of selterbelt on the pastureland in the farm of Short -horn Ox Farm of Chifeng City of Inner mongolia-Populus spp. was studied.Growth condition of Populus spp. in different site types was widely investigated.The relationship between the different varieties. of Populus spp. and its site was systematically analysed by the comprehensive methods of intuitive analysis and mathematical statistics. Dominant site factors of Populus spp. was found out,which is the volume weight of soil. Mathematical model of them was established and suitable sites were pointed out.
