| 摘 要： | 介绍了包裹式茎流计测量植株液流的原理,应用茎流计测量了1株典型性龙爪槐的树干液流日进程,分析了树干液流与大气温度、累计液流量的关系。结果显示,龙爪槐干液流日进程白天变化比较大,呈现多峰曲线形式;夜间数值较低且相对平稳。大气温度、累计液流量日进程变化趋势与树干液流相一致。

| Abstract: | The principle of packaged sap flow gauge in measuring stem flow flux was introduced and then it was used to measure the diurnal change stem sap flow of a typical locust tree.The relationship between diurnal change of stem sap flow with air temperature and diurnal accumulation of stem sap flow were analyzed,too.Results showed that the diurnal change of stem sap flow in daytime was variable,showing multi-peaks characteristics and relatively stable and in nighttime was with low value.Air temperature and accumulation of stem sap flow's diurnal change showed uniform trend with trunk stem sap flow. |
