摘　　要：以新疆森林资源面积和各林龄组面积、年净生产力为基础数据,按国家林业行业标准规定的方法,测算天然胡杨林不同林龄固碳量与释氧量和货币价值量。结果表明:天然胡杨林固碳量为1 004 264.21 t/a,释氧量为1 108 060.93 t/a;固碳价值为120 511.63万元/a,释氧价值为143 948.54万元/a,总价值为264 460.17万元/a,南疆地区高于北疆;各龄组中,中龄林固碳释氧功能量和价值量最高,达880 811.30 t/a和109 814.15万元/a,过熟林最低,仅为65 297.09 t/a和8 114.36万元/a。According to method from the China National Forest Standard,the amount of carbon sequestrated and oxygen released,and currency value were calculated,based on the forest resource inventory data,the stand age area for management,and the net primary productivity in Xinjiang.The results showed that the annual total carbon sequestrationin of natural Populus euphratica in Xinjiang was 1004264.21 t/a,the oxygen release was 1108060.93 t/a;the carbon fixation value was 1205116300 yuan/a,the oxygen release value was 1439485400 yuan/a,and the total value was 2644602300 yuan/a,which was higher in southern Xinjiang than in northern Xinjiang.In the all age,the function and value of carbon fixation and oxygen release in the middle aged forest are the highest,up to 880811.30 t/a and 10.98 billion yuan/a,the oldest forest was the lowest,only 65297.09 t/a and 0.8 billion yuan/a.
