Other Abstract

在贡嘎山海螺沟冰川退缩区植被原生演替序列不同演替阶段设置7个样地,分别对7个样地的环境因子进行连续观测试验,对各个样地的植物、土壤碳、粗木质物残体的有机碳含量进行测定。结果表明:原生演替序列7个样地的有机碳储量分别为: 889.3, 8930.3, 13902.5, 17021.5, 19699.9,26121.9,34587.4 g C·m-2。样地的有机碳储量按大小顺序排列为:植被>土壤>粗木质物残体。7个样地的土壤呼吸C排放分别是326.7,265.7,260.3,382.5,555.6,774.9,1030.5 g C·m-2·a-1。在未来气候变化情景模式下,不同演替阶段林分的土壤呼吸量均随着温度的增加而增加,演替初期生态系统的土壤呼吸季节模式会发生显著变化,对气候变化更加敏感,演替后期的变化较小。植被原生演替序列总有机碳储量呈现持续增加的趋势,在演替中后期碳汇作用变强。

Seven sampling sites in vegetation primary succession of Hailuogou glacier recession site,Mount Gongga,were set for observation to analyze organic carbon content in vegetation,coarse woody debris and soil.Continuous observation and tests in this seven sites were also carried out. Result showed that the organic carbon
storages in seven sites of the primary forest succession were: 889.3,8930.3,13 902. 5,17021.5,19 699. 9,26121. 9,34 587.4 g C·m -2,and the ecosystem components ranged as vegetation > soil > coarse woody debris as comparing with the organic carbon storage. The carbon flux of soil respiration for the seven sites were: 326.7,
265. 7,260.3, 382.5,555.6,774. 9,1030.5 g C·m - 2·a - 1 separately。In case of future climate change,soil respiration in different stages of succession will increase with temperature growth. The seasonal pattern of soil respiration in early stage of succession changes significantly and it would be more sensitive to climate change,while the variation tends to be more moderate in later succession. Total organic carbon storage of ecosystem showed a trend of increasing in succession,and the efficiency of carbon sink in later succession were stronger.
