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.

Key words: transpiration, tree-planting pattern, carbon sink forest, Junggar Basin, Xinjiang
