摘要： 干旱区水资源极端匮乏,造林前后林分耗水变化的数据是必不可少的。通过对俄罗斯杨(Populus russkii)、新疆杨(Populus alba var.pyramidalis)和原始背景梭梭(Haloxylon ammodendron)树干液流的观测,通过边材面积作为转换纯量,计算出林内的蒸腾耗水量;通过枝基径和枝截面积作为转换纯量,计算了林外荒漠梭梭林的蒸腾耗水。通过对比林内外蒸腾耗水的差异,得出人工碳汇林造林前后蒸腾耗水的增量,克拉玛依人工碳汇林日蒸腾耗水量是土著植被的19倍。

Abstract: The study area was located in western Junggar Basin where the water resources are extremely scarcity. It is important to investigate and analyze the transpiration of the artificial forest before and after the afforestation. Through monitoring the sap flows of Populus russkii, Populus alba var.pyramidalis and Haloxylon ammodendron, we calculated the transpiration of the plantations within the artificial forest as well as the evapotranspiration of the Haloxylon forest around the plantations in the natural desert environment. Sapwood area was selected as the conversion scalar. The results showed that there was a significant difference in transpiration within the plantation from that outside the plantation. The water consumption from the transpiration within the plantation was 19 times of that of the Haloxylon forest around the plantation in Karamay.
