摘要
柳树在西藏广泛种植,占人工林的30.10%,发挥了固碳释氧等生态功能。以柳树为研究对象,研究柳树人工林的分布、碳累积规律及影响碳密度的因素。研究结果表明,区域、树种、林龄对柳树碳密度均有显著影响。林芝地区、雅鲁藏布江中游地区柳树碳累积速率大。柳树碳汇与林龄、经度呈正相关,与纬度、海拔、距农田的距离、距水域的距离呈负相关。
The distribution of Salix spp.plantation are wide in Tibet,accounting for 30.10%of the total plantation,which plays an ecological role in carbon sequestration and oxygen release.This paper studied the distribution,the rule of carbon accumulation and the factors affecting carbon density of Salix spp.plantation.The results showed that region,tree species and forest age had significant effects on the carbon density.The carbon accumulation rate of Salix spp.in Linzhi and the middle reaches of the Yarlung Zangbo River was high.The carbon sink was positively correlated with forest age and longitude,and negatively correlated with latitude,altitude,distance from farmland and distance from water area.
