| 摘 要： | 通过生物量换算因子法,以新疆伽师县"三北"防护林为研究对象,根据2008年底森林资源调查数据,研究了林分郁闭度和龄级对防护林碳汇功能及固碳价值的影响.结果表明:碳密度和生物量随龄级的增加呈上升趋势;生物量和碳密度也随郁闭度的增加呈波浪形上升趋势.幼龄林、中龄林、近熟林、成熟林、过熟林的年碳吸收率分别为3.0、2.8、3...

| Abstract: | Biomass-conversion factor method was used to study the influences of crown density and age class on function and value of carbon sequestration of shelter forests in Jiashi County,Xinjiang,according to the forest resource data from the survey conducted at the end of 2008.Results showed that the carbon density and biomass of the shelter forests exhibited an upward trend with age class and an undulating increase with canopy density.Annual carbon absorption rates of young forest,middle-aged forest,near-mature f... |
