摘要: 对毛乌苏沙地不同平茬时间的沙柳(Salix psammophila)进行调查和取样,计算和分析了沙柳的碳汇能力及生产力配置格局。结果表明:平茬对沙柳的碳储量以及生产力的增加明显具有促进作用;在不同的平茬年限中,2年平茬沙柳固碳量最大,达6.37t/(hm2·a),3年平茬次之;沙柳在3年平茬时生产力格局最优,生产力达29.21t/(hm2·a),2年平茬次之。总体来说,沙柳2年平茬碳汇功能最强,3年平茬生产力分配格局最优。

关键词: 沙柳, 平茬, 碳汇, 生产力

Abstract: Based on the survey and sample for Salix psammophila stumping in different time periods in Mu Us sandy land,calculation and analysis have been conducted on carbon sinks capacity and productivity allocation pattern.The results showed that:stumping can promote carbon reserves and the increase of productivity.In the different levels of stubble,the best carbon sequestration is 6.37t/(hm2·a) in 2nd year,the second is stumping in 3rd year.And the optimal productivity is 29.21t/(hm2·a) in stumping in 3rd year,the second is stumping in 2nd year.In general,the best carbon sinks capacity of Salix psammophila is stumping in 2nd year,the best productivity allocation pattern of Salix psammophila is stumping in 3rd year.

Key words: Salix psammophila, stump, carbon sinks, productivity
