摘　　要：近年来,我国人工林面积不断增加,人工林在我国陆地森林生态系统碳收支中的作用越来越大。以克拉玛依人工杨树林和荒漠灌木林为研究对象,通过样地调查,对生物量及碳储量、碳密度、碳汇功能等进行了估算。通过实测数据及模型分析,得出以下基本结论:1该人工杨树林单位面积生物量平均为51.30 t·hm-2;碳密度平均为24.59 t·hm-2,碳储量为73 715.41 t,说明其发挥着一定的碳汇作用。2与荒漠环境下灌木林对比结果表明,克拉玛依人工杨树林单位面积生物量增加了50.56 t·hm-2,碳密度增加了24.26 t·hm-2,碳储量增加了72 726.14 t,表明在干旱区荒漠环境下通过造林来增加区域陆地植被碳汇,进而达到碳减排的目的是可行的。With the expanding of the plantations in recent years,artificial forestry plays a more and more important role in carbon budget of the terrestrial ecosystem in China. This study estimated biomasses,carbon stocks,carbon densities and carbon sinks of the poplar plantations and the desert shruberies in Karamay through field investigations. According to the data observed and the modelling analysis,the study came with the following conclusions：1 The average unit biomass of the poplar plantations was 51. 30 t·hm^- 2; mean carbon density was 24. 59 t·hm^- 2; the total carbon storage was 73 715. 41 t,which demonstrated that poplar plantations played a certain role in carbon sequestration. 2 Compare with under the desert shrubberies,biomass,mean carbon density and the total carbon storage of poplar plantations increased 50. 56 t·hm^- 2,24. 26 t·hm^- 2and 72 726. 14 t,respectively. The results of the study indicated that afforestation can effectively increase the carbon sequestration of the terrestrial vegetation ecosystem in a desert environment in arid areas. It is a feasible way to achieve the carbon emission targets.
