摘要
对徂徕山不同立地条件的刺槐Robinia pseudoacacia人工林进行调查,并进行立地分类与立地质量评价。利用回归分析和数量化理论Ⅰ确定了徂徕山刺槐生长的主导环境因子为坡向、坡度和土层厚度;构建了徂徕山刺槐人工林立地质量评价模型:Y=1.677+0.251X4+0.019X2+0.033X3。利用这一模型将徂徕山立地分6类,并对立地质量数量化评价:得分值大于16.6981的立地适宜发展刺槐,而得分值小于16.6981的立地则不适宜刺槐的生长。
Investigations were carried out on 25-year Robinia pseudoacacia plantations in Culai Mountain,Tai’an,Shandong province.Temporary sample plots were established in stands with different site condition for site quality evaluation.Regression analysis and quantified model I demonstrated that the dominant environmental factors for the growth of R.pseudoacacia were slope aspect,slope gradient and soil thickness.Site quality evaluation model for R.pseudoacacia plantation in Culai Mountain was Y=1.677+0.251X4+0.019X2+0.033X3.R.pseudoacacia plantation in Culai Mountain could be divided into 6 types by the model.Quantification evaluation on site quality indicated that site with score greater than 16.698 was suitable for the growth of R.pseudoacacia.
