摘　　要：【目的】量化克拉玛依市10万亩减排林区的固碳效益,为西北荒漠地区森林资源管理决策提供理论依据。【方法】调查克拉玛依市10万亩减排林区标准样地内树木的种类、株树、胸径、高度、盖度等,由此估算出该地区的固碳价值量及单位面积森林的固碳效益。【结果】克拉玛依市10万亩减排林区共有活立木蓄积量1.43×106m3,现存生物量2.21×106t,固定CO2实物量3.60×106t,折合纯C量9.81×105t,固碳价值量2.15×108元,年均单位面积森林的固碳价值为32250元/ha。【结论】克拉玛依市10万亩减排林区森林生态系统在维持生物圈CO2和O2动态平衡、减缓温室效应等方面具有一定的积极作用。[Objective]Carbon fixation benefits were evaluated in 100 thousand mu（6667 ha） emission reduction forests of Karamay City in order to provide theoretical references for forest resources management in Northwest desert areas and other parts of country.[Method]The carbon fixation value and carbon fixation benefits per unit area of 100 thousand mu emission reduction forest of Karamay area were estimated on the basis of number of trees and their varieties,tree diameter,tree height and canopy area.[Result]In the Karamay emission reduction forest,the fresh wood volume was recorded as 1.43×106 m3,total biomass was 2.21×106 t,physical quantity of carbon fixation was 3.60×106 t and converted pure C amount was 9.81×105 t.The carbon fixation value was estimated as 2.15×108 Yuan,and carbon fixation value per unit area was recorded as 32250 Yuan/ha.[Conclusion]The emission reduction forests of Karamay were found to play a very important and positive role in maintaining dynamic balance between CO2 and O2 in biosphere and reducing the effects of global warming.
