摘要: 以河南登封嵩山地区不同坡向的油松人工林为对象,分别建立了跑马岭、峻极峰及区域油松差值年表。结果表明: 跑马岭油松年表的质量高于峻极峰油松年表;跑马岭油松年表和峻极峰油松年表都包含较高的气候信息,都与当年2月平均气温、生长季末期(9—10月)平均气温和平均最高温呈显著正相关,与当年5月的平均最高温呈显著负相关;跑马岭和峻极峰油松径向生长对气候响应有一定的差异,跑马岭油松径向生长主要与3月平均最低温和9月降水量呈显著正相关,而峻极峰与5月降水量和9月平均最低温呈显著正相关;区域油松年表包含了更多的气候信息。利用多元回归分析方法能较好地模拟出油松树轮宽度生长的限制因素是多个月的温度,尤其是当年9月平均气温,这与相关分析结果一致。本研究可以为本地区森林保护和生态建设提供基础服务。

Abstract: Taking Pinus tabuliformis plantations at different slopes in Songshan Mountains, Henan Province, China as subjects, we established different residual chronologies of P. tabuliformis in Paomaling (PML) and Junjifeng (JJF) and whole region (RC). The results showed that the chro-nological quality of PML was higher than that of JJF. Chronologies of PML and JJF had more climate information, which had significant positive relationship with mean temperature in current February, mean temperature and mean maximum temperature at the end of growing season (September-October), and significant negative relationship with mean maximum temperature in current May. The response of radial growth of P. tabuliformis to climate differed in PML and JJF. Radial growth of P. tabuliformis in PML was positively correlated with mean minimum temperature in March and precipitation in September, while that in JJF was positively correlated with precipitation in May and mean minimum temperature in September. Residual chronologies of P. tabuliformis in whole region contained more climate information. The multiple regression analysis method was used to simulate that the main limiting factors of tree-ring width growth of P. tabuliformis, which was a range of temperature indicators, especially current mean temperature in September. The result was consistent with that of correlation analysis. This study could provide basic services for forest protection and ecological construction in Songshan Mountains region.
