【摘要】：基于2002年、2007年和2012年3期森林资源清查资料,采用马尔科夫模型和复利公式,分别对2012—2027年16年间云南省森林资源面积结构和蓄积量变化进行预测,并应用生物量经验(回归)模型估计法和植被含碳率,对云南省森林植被的生物量、碳储量和碳密度进行预估。结果表明:16年间云南省森林植被面积和蓄积量将呈现双增长趋势,面积和蓄积量年均增长率分别为0.50%和2.94%,森林植被碳储量和平均碳密度均呈持续增长趋势,分别由890.40Tg和41.89Mg/hm~2提高到1265.34Tg和55.41Mg/hm~2,年均增长率分别为2.81%和2.15%。随着幼、中龄林的发展成熟,以及抚育经营使森林质量提高,云南省森林碳汇潜力巨大。
[Abstract]:Based on the inventory data of forest resources in 2002, 2007 and 2012, using Markov model and compound interest formula, the area structure and volume change of forest resources in Yunnan Province from 2012 to 2027 were predicted, respectively. The biomass, carbon storage and carbon density of forest vegetation in Yunnan Province were estimated by using empirical (regression) model and vegetation carbon content. The results showed that the area and volume of forest vegetation in Yunnan Province showed a double increasing trend during the past 16 years, the average annual growth rates of area and volume were 0.50% and 2.94, respectively, and the carbon storage and average carbon density of forest vegetation showed a sustained increasing trend. From 890.40Tg and 41.89mg / hmc-2 to 1265.34Tg and 55.41mg / hm-2 respectively, the average annual growth rate is 2.81% and 2.15%, respectively. With the development and maturity of young and middle aged forest and the improvement of forest quality by tending management, forest carbon sink potential in Yunnan Province is great.
