运用相关函数及单年分析等树木年轮气候学方法,研究了黑龙江凉水国家自然保护区不同皮型红松径向生长与气候因子的关系、主要影响因子及这种响应关系是否长期稳定.结果表明:细皮红松更适合做树木年轮气候学分析.两种皮型红松的径向生长对环境变化都比较敏感,对气候因子的响应无显著差异.1902—2009年生长季,尤其当年6月的气候因子是影响研究区两种皮型红松生长的主要因子.其中,温度表现为显著负相关,降水表现为显著正相关.不同时间段内红松径向生长对气候因子的响应存在差异,随着1970年后气温的快速升高及干旱的加剧,两种皮型红松径向生长对气候因子的响应更敏感,尤其表现为对生长季温度和更多季节水热复合因子变化(帕尔默干旱指数)的响应更显著.
The relationships between climatic factors and climatic factors of different kiwifruit types in Liangshui National Nature Reserve of Heilongjiang Province were studied by means of correlation function and single-year tree-ring climatological analysis. The main influencing factors and the long-term stability of this response relationship were analyzed. The results showed that Pinus koraiensis was more suitable for climatological analysis of tree rings.The radial growth of both species was sensitive to environmental changes and no significant difference in response to climatic factors.From 1902 to 2009, The climatic factors in June of that year were the main factors affecting the growth of two species of Pinus koraiensis in the study area, of which temperature showed a significant negative correlation and precipitation showed a significant positive correlation.Dark growth of Korean pine in different time periods had no significant effect on climatic factors With the difference of response, with the rapid increase of air temperature after 1970 and the aggravating of drought, the radial growth of the two types of kiwifruit is more sensitive to the climatic factors, especially for the season and more seasonal hydrothermal complex The response to changes in factors (the Palmer Drought Index) was even more pronounced.
