| 摘 要： | 应用热扩散原理,采用ICT-2000TE自动测定系统,对岷江流域冷杉的树干液流及其主要环境因子进行了同步测定,分析了冷杉的树干液流动态变化规律。结果表明:冷杉的树干液流变化呈现明显的单峰曲线,液流速率的峰值一般出现在中午12或13时;影响冷杉树干液流大小的主要环境因子包括光合有效辐射、空气温度和空气相对湿度,但相关密切的是光合有效辐射。

| Abstract: | The dynamics of stem sap flow of Abies fabric in Mingjiang valley,which were the fundamental to research the hydrological recycle of this standing,were measured using ICT-2000TE based on thermal dissipation method in 2003.The results showed that the sap flow rate exhibited mono-peak patterns during day's dynamics,and the maximum sap flow rate occurred at 12 or 13 o'clock.The main environmental factors to affect the sap flow rate of A.fabric included solar radiation,air temperature and air relative humidity.The correlation analysis indicated that there existed a close correlationship between solar radiation and sap flow rate. |
