| 摘 要： | 对采自辽宁彰武、阜新、建平和山西方山、吉县的672个油松树芯进行精确的交叉定年和量测后,采用COFECHA程序检验定年质量,并对定年质量的影响因素进行对应分析,结果表明:各试验地点样地内树芯间的相关度为0.3807～0.7175,具有明显的地域性。山西试验地样芯的相关度明显高于辽宁,而样芯的平均敏感度则差异不明显;与主序列不一致的样本标记A与由于伪轮或缺轮导致的标记B这两种现象的发生,辽宁也多于山西;两种标记的出现与坡度、坡位、林分密度和抚育间伐等影响因素存在较为密切的关系。 |
| 关 键 词： | 油松人工林 年轮 序列相关度 平均敏感度 影响因素 |

| Abstract: | After rigorous cross-dating and measuring of 672 of Pinus tabulaeformis core series gathered from Zhangwu,Fuxin,Jianping of Liaoning Province and Fangshan,Jixian of Shanxi Province,the quality of the cross-dating was checked using the COFECHA program and the influencing factors were analysed using MCA.The results showed that:(1) the series inner correlation ranged from 0.3807 to 0.7175,and they had apparent regional characteristics,while the series inner correlation of Shanxi was obviously higher than that ... |
