Abstract： 分别于7月15H～8月7H(夏季期)和9月5日～10月9H(秋季期),在山西芦芽山林线附近,应用树木径向变化记录仪(Dendrometer)分别测量了3株和4株华北落叶松树干的径向生长过程,并同步监测环境因子.结果表明:1)华北落叶松茎干变化在晴好天气呈现出有规律地波动式上升,在阴雨天气下则表现为持续上升,降雨结束后迅速下降;2)茎干变化在7～8月观测期内与土壤含水量、空气温度正相关,在9～10月观测期内与土壤含水量正相关,与土壤温度、空气温度负相关;3)径向净生长在夏季期为正,在秋季期为负,在9月初先下降,在9月中期后基本保持为0;4)在两个观测期内,径向净生长与空气温度负相关,与土壤含水量显著正相关.图5表5参21
