| 摘 要： | 通过逐步回归方法,分析了辽河源地区主要针叶树种生长与土壤因子的相关关系。结果表明:影响落叶松胸径、树高和材积的主要土壤因子为全钾、碱解氮和速效磷;影响油松胸径、树高和材积的主要土壤因子为全氮、全钾、密度、毛管孔隙度和非毛管孔隙度。土壤因子之间是互相关联、互相影响、共同作用的,均对树种的生长产生直接或间接的影响。 |

| Abstract: | A survey was conducted to study the correlations between soil factors and growth of the main coniferous species in the source areas of Liaohe River by stepwise regression method.Results show that the dominant soil factors influencing the diameter at breast height,tree height and volume of larch are contents of total potassium,available nitrogen and available phosphorus,while those affecting Pinus tabuliformis are total nitrogen content,total potassium content,volume weight,capillary porosity and non-capillary porosity.There are interconnections,mutual influences and interactions between all the soil factors,which affect tree growth directly or indirectly. |
| Keywords: | Source areas of Liaohe River Larch Pinus tabuliformis Soil factors Correlation analysis |
