摘　　要：以北京山区主要造林树种刺槐为研究对象,采用数量化理论Ⅰ的方法,通过研究不同立地因子对人工刺槐林高生长与径生长的影响来分析刺槐的适地性。结果表明:土壤厚度、坡度是制约人工刺槐林高生长的最重要因子,坡位、土壤类型是影响人工刺槐林高生长的重要因子;土壤厚度是制约人工刺槐林径生长的最重要因子,坡度是影响人工刺槐林径生长的重要因子。研究结果确定了影响北京山区刺槐人工林生长的主导因子,可以为刺槐造林地的选择和科学经营提供依据。Taking the afforestation tree species Robinia pseudoacacia in Beijing mountainous area as the research object, the site suitability of Robinia pseudoacacia is analyzed through studying the impacts of different site factors on the height growth and diameter growth of Robinia pseudoacacia using quantitative theory I. The results show that soil depth and slope affect the height growth of Robinia pseudoacacia, slope position and soil type affect the height growth of Robinia pseucloacacia, soil depth affects the diameter growth of Robinia pseudoacacia, slope affects the diameter growth of Robinia pseudoacacia. The research resutls determine the leading factors to affect the growth of Robinia pseudoacacia in Beijing mountainous area, which can provide the basis for site choice and scientific management of Robinia Dseudoacacia plantations.
