基于水热优化NPP气候模型和土壤呼吸Q10模型,对辽宁省近50年(1961～2008年)森林固碳和碳释放的年际变化特征进行分析模拟.结果表明,近50年,辽宁森林固碳量呈现逐渐增加的趋势,2008年固定的总CO_2量达到83.9 Mt,为1961年的2.8倍;单位面积森林固碳水平随着气候年景而有起伏变化,固碳最高年份与最低年份偏多36.5%;辽宁森林总体为碳汇,每年单位面积平均碳汇量为2.1 t.

Based on H_2O-heat optimized NPP model and Q10 model of soil respiration, the interannual change characteristics of NPP and carbon emission of Liaoning forest in recent 50 years (from 1961 to 2008) were analyzed. The results indicated that the total amounts of annual NPP showed increasing trend in recent 50 years, in which the amount of NPP in 2008 was 2.8 times more than that in 1961. Amounts of NPP per unit area changed with different climatic years, and the maximum value was 36.5% more than the minimum one. The net carbon budget of Liaoning forest was carbon sink, with 2.1 t per unit area of average sinking amount.
