毛乌素沙地典型树种蒸腾耗水特征及其与气象因子的关系
Characteristics of transpiration water consumption of typical tree species in Mu Us Sandy Land and its relationship with meteorological factors
[目的]通过对毛乌素沙地人工植被茎流蒸腾速率及其与气象因子的关系进行研究,探究旱柳(Salix matsudana)和小叶杨(Populus simonii)的蒸腾耗水量及影响因子。[方法]采用热扩散式插针茎流计(TDP)测定树干液流与自动气象站监测微气象因子,运用Granier公式计算出旱柳和小叶杨的蒸腾茎流量,研究其与气象因子的关系。[结果]旱柳和小叶杨的茎流日变化呈单峰"几"字型曲线,表现出明显的昼夜变化规律,7:00 左右茎流启动到 12…查看全部>>
[Objective]To explore the transpiration water consumption and its influencing factors of Salix matsudana and Populus simonii by studying the transpiration rate of artificial vegetation stem flow and its relationship with meteorological factors in Mu Us sandy land.[Method]The thermal dissipation probe sap flow meter(TDP)was used to measure the sap flow and the automatic weather station was used to monitor the micro-meteorological factors.The Granier formula w…查看全部>>
