| 摘 要： | 为确定河南省丘陵低山区刺槐适宜的生长环境，为刺槐的经营管理和立地生产潜力提升提供参考。以河南省丘陵低山区106块1～26年生刺槐人工林为研究对象，采用典型抽样方法，调查样地内对树高生长有显著影响的环境因子，利用数量化理论Ⅰ分析各调查指标对刺槐生长的影响，对刺槐人工林进行立地类型划分与立地质量评价。结果表明，影响刺槐人工林立地质量的主要环境因子依次为土壤质地、海拔高度、土层厚度、坡向；复相关系数的t检验得t=14.96,复相关系数及各立地因子偏相关系数均达显著水平，此次所构建的数量化立地指数表适用于河南省丘陵低山区刺槐人工林。采用土壤质地、海拔高度、土层厚度、坡向4个主要因子的组合，划分为10个立地类型组、80个立地类型。将80个立地类型划分为好、中、差3个立地等级，对每个立地类型立地质量评价分析得出，研究区有75%的样地立地质量在中等以上。河南省丘陵低山地区刺槐人工林最适宜生长的环境为中厚(>30 cm)、壤土、小坡度、阴坡。

| Abstract: | The objective of this study was to determine the suitable growth environment of Robinia pseudoacacia in the hills and low mountains in Henan Province to provide a reference for the management of R.pseudoacacia and the improvement of site production potential.Taking 106 1-to 26-year-old R.pseudoacacia plantations in the hilly and low mountainous areas in Henan Province as the research objects,the typical sampling method was used to investigate the environmental factors that had significant impacts on the tree height growth in the sample plots,and the quantitative theory-I was used to analyze the influence of each survey index on the tree growth.The site type classification and site qualitative evaluation were carried out.The results showed that according to the geographical environment and quantification theory-I,the main environmental factors affecting the site quality were soil texture,altitude,soil layer thickness,and slope aspect.The test of the multiple correlation coefficient yielded t=14.96,the multiple correlation coefficient and the partial correlation coefficient of each site factor reached significant levels.The quantitative site index table constructed was suitable.Using the combination of soil texture,altitude,soil layer thickness and slope aspect,10 site type groups and 80 site types were classified.The 80 site types were divided into three site grades:good,medium and poor.The site quality evaluation and analysis of each site type showed that 75% of the sample sites in the study area were above medium grade.The most suitable growth environment was medium thickness (>30 cm),loam,sunny slope and light grade slope. |
