摘　　要：依据云南省历次森林资源清查数据,采用云南省林业调查规划院建立的思茅松生物量与蓄积量模型和碳系数,计算各调查年份的生物量和碳储量,分析云南省39年来思茅松林碳储量、碳密度变化情况。结果表明,思茅松幼龄林碳储量变化趋势为稳中略升,碳密度变化趋势为稳步增大;中龄林碳储量急剧减少,碳密度略有降低;近熟林碳储量稳步增加,碳密度小幅提升;成熟林碳储量变化趋势为减少,碳密度变化趋势为增大;过熟林碳储量变化趋势为减少,碳密度变化趋势为增加。人工林碳储量总体变化趋势为增加,碳密度总体变化趋势为小幅增加;天然林碳储量总体变化趋势为下降,碳密度总体变化趋势为增加。思茅松龄组、起源等结构上的变化趋势有增有减、有升有降,但生物量和碳储量的总体变化趋势为减少,碳密度呈上升趋势。Based on the data of forest resources inventory in Yunnan Province,the model of biomass and carbon storage and the carbon coefficient established by Yunnan Institute of Forest Inventory and Planning were used to calculate the the biomass and carbon storage of Pinus kesiya var.langbianensis forest and analyze the changes of carbon storage and density in Yunnan Province in the past 39 years.The results showed that the carbon storage increased slightly in stability and the carbon density increased steadily in young Pinus kesiya var.langbianensis forest;the carbon storage decreased sharply and the carbon density decreased slightly in middle-aged forest;the carbon storage increased steadily and the carbon density increased slightly in premature forest;the carbon storage decreased and the carbon density increased in mature forest and over-mature forest.The overall change trend of carbon storage in plantation was increasing,while the change trend of carbon density was slightly increasing.The overall change trend of carbon storage was decreasing in natural forest,while the change trend of carbon density was increasing.The age group and origin of Pinus kesiya var.langbianensis had various structural changes,but the overall change trend of biomass and carbon storage was decreasing,and the carbon density was increasing.
