摘要: 利用回归分析、马尔可夫过程模拟预测、抽样统计等方法,对甘肃灌木林发展空间、林种面积、生产力及碳汇潜力进行了研究。结果表明:到2050年灌木林发展可望达到571.5万hm2,未来灌木林发展的潜力在非林区;灌木林生产力较低,且差异较大;灌木林碳储量较丰富,2011年和2050年分别为1 140和2 310万t,平均碳密度由3.160 9 t/hm2增加到4.042 1t/hm2,碳密度的提高得益于新造生产力较高灌木林面积的增长。

Abstract: Based on the approaches of the regression analysis,the Markov prediction and the sampling statistics,the study of the development potentials,the forest planting area,the productive forces and the carbon storage potentials of the shrubbery in Gansu province were carried out.The results are as follows:(1)the area of the shrubbery will potentially reach 5,715,000 hm2 till 2050 and non-forest areas will be the potential areas for the development of the shrubbery in the future;(2)the shrubbery is featured by the weak productive forces and the great differences;(3)the shrubbery possesses the abundant carbon storage,which is revealed by the storage of 11,400,000tC in 2011and 23,100,000tC in 2050 respectively and the average carbon density will increase to 4.0421tC.hm-2 from 3.1609tC.hm-2,which benefits from the increase of newly planted shrubbery with the better productive forces.
