Abstract:

树木年内径向生长动态监测对理解树轮-气候响应的生理机制具有重要意义。本文利用树木径向生长测量仪(Dendrometer)对祁连山东部吐鲁沟国家森林公园内3棵祁连圆柏生长季径向生长进行监测。监测结果发现祁连圆柏树干径向变化呈日周期波动,上午07:00~08:00膨胀到最大值,而在下午16:00~17:00收缩至最小值。监测显示的祁连圆柏主要生长时期为5月初到7月上旬,与早材细胞形成时期一致,在5月底到6月初达到最大生长速率。通过周期法提取日径向增长量(SRI),并与不同阶段气象因子进行相关分析,发现SRI与收缩阶段气象条件没有显著关系,而与膨胀阶段和增长阶段气象因子显著相关,说明16:00~17:00至07:00~08:00气象条件对径向生长的重要作用。SRI与降水量和相对湿度显著正相关,与水汽压亏缺(VPD)显著负相关,表明本地区祁连圆柏生长受到水分条件限制。相关分析还表明,SRI与平均气温和最低气温负相关。多元线性模型分析显示,相对整个周期,膨胀阶段和增长阶段气象数据能解释更多的径向生长变化,解释量高达87.1%。
