摘  要：
以云南景谷为研究对象,以追求最大固碳效率为出发点,研究和评价了计划烧除和常规林2种不同森林管理模式下腐殖质层含水率、厚度、载量和有机碳贮量,以及0～60 cm土壤层次有机碳含量和有机碳贮量来分析计划烧除对土壤的固碳效率。结果表明,思茅松经计划烧除林腐殖质层厚度较常规林平均厚0.527 cm,载量高3.362 t/hm2,平均有机碳贮量高2.145 t/hm2;不同立地条件下经计划烧除林0～60 cm土层有机碳含量与常规林同层次相比,都高出约0.5%;经计划烧除林土壤有机碳贮量比常规林高38.526 t/hm2,说明计划烧除可增加森林土壤的固碳量,达到森林增汇效益。

摘  要：
Jinggu in Yunnan was viewed as research object,from the pursuit of maximum efficiency of the largest carbon sequestration as a starting point,research and evaluation prescribed burning and regular forest under two different forest management models moisture content of humus,thickness,load and organic carbon storage,and organic carbon content of 0-60 cm of soil carbon levels and organic carbon storage to analyze prescribed burning efficiency of soil carbon sequestration.Results show that kesiya forest humus by the planning burning average is thicker than conventional thick forest with 0.527 cm,contained high levels of 3.362 t/hm2,average organic carbon storage of 2.145 t/hm2.0–60 cm soil depth,the prescribed burning forests of different organic carbon content and different slope compared to the same level of conventional forest,are up nearly 0.5%;by the planning burning forest,forest organic carbon storage are higher than 38.526 t/hm2 of conventional forest,from the three aspects of the data,it prescribed that the burning of forest soil carbon sequestration can increase the amount of benefits to forest sinks.
