在样地调查的基础上,利用青海云杉胸径要材积的一元模型、青海云杉林蓄积要生物量模型、相关分析和主成分分析法,对甘肃祁连山青海云杉林的蓄积量、生物量、碳储量以及影响青海云杉林碳储量的主要因子进行了研究。结果表明,青海云杉林单位面积的蓄积量、生物量和碳储量平均值分别为223.445 4 m^3/hm^2、136.075 5 t/hm^2和96.186 4 t/hm^2;总生物量和碳储量分别达到2.59×10^7t和1.52×10^7t,其中中龄林和近熟林的生物量和碳储量分别占总量的42.581 8%和41.134 8%,而幼龄林仅占1.080 9%;影响森林植被碳储量的主要因子为环境水热状况,温度是影响祁连山森林植被碳储量最关键的因子。
Based on sample survey,using a meta model of DBH-volume of Picea crassifolia, stand volume-biomass mode] of Picea crassifolia forest, correlation analysis and principal component analysis,the stand volume ,biomass, carbon storage and the main factors affecting the carbon storage of Picea crassifolia forest in Gansu Qilian Mountains were studied.The results showed that the stand volume ,biomass and carbon storage of per unit area averages was 223.445 4 m^3/hm^2,136.075 5 t/hm^2 and 96.186 4 t/hm^2.The total biomass and total carbon storage reached 2.59×10^7 t and 1.52×10^7 t,biomass and carbon storage of mid-age forest and near-mature forest accounted for 42.581 8% and 41.134 8% of the total,respectively,and young forest accounted for only 1.080 9% .The main factors that affectd the forest vegetation carbon storage was hydrothermai condition of the environment, the temperature was the most critical factor affecting forest vegetation carbon storage in Qilian mountains.
