| 摘 要： | 2003年5-10月,对黑河下游额济纳绿洲中一块25年生的胡杨林耗水进行了研究,结果表明通过标准木的标准比导率和树木胸径和边材面积的相关模型,可以比较准确地推算出林分的蒸腾耗水量。胡杨林的蒸腾耗水量具有明显的季节差异;胡杨幼林在生长季节耗水量为213.4mm。林分的生长状况主要受地下水位和土壤含水量的影响。

| Abstract: | The heat-pulse technique was applied to determine the stem sap flow of 25a Populus euphratica in May to Oct of 2003, and to calculate the forests water consumption. The results show that Populus euphratica stern sap flow was linearity correlated to area of sapwood and the tree diameter. The water consumption of Populus euphratica were different among seasons. The young tree spent water 213. 4mm in growth period. The forest growth was affected by groundwater level and soil moisture. |
