| 摘 要： | 准确评估区域范围内森林生态系统的固碳能力和趋势，系统分析不同森林类型的固碳能力时空异质性，对于实现森林可持续经营和固碳增汇具有重要意义。以河南省第八次森林资源清查数据为基础，运用生物量扩展因子法，研究了河南省乔木林植被的碳储量及碳密度特征。结果表明:2013年河南省乔木林植被碳储量7 422.78万t，其中栎类、杨树2个（组）树种植被碳储量占全省乔木林植被碳储量的67.32%。河南省乔木林植被平均碳密度为24.31 t/hm2，低于全国平均水平。河南省乔木林以幼、中龄林为主，其植被碳储量分别占全省乔木林植被碳储量的34.09%和40.84%。河南省天然林、人工林植被的碳储量相差不大，分别为3 512.35万t和3 910.43万t；平均碳密度分别为26.72 t/hm2，22.49 t/hm2。研究表明河南省乔木林植被，特别是人工林，未来固碳潜力巨大，将会在森林植被碳储量中占有越来越重要的地位。

| Abstract: | It is important to accurately assess carbon sequestration ability and trends in forest ecosystems and systematically analyze tempo-spatial heterogeneity among various forest ecosystems and controlling factors to achieve sustainable forest carbon sinks. Based on the eighth forestry inventory data, the carbon storage and carbon density of arboreal forests in Henan Province, China was estimated. In addition, the characteristics were analyzed according to dominant tree species, age groups and forest origins. The results showed the total carbon storage of arboreal forests vegetation amounted to 74.227 8 million tons in 2013, in which Deciduous oaks and Populus forest accounted for 67.32%; the average carbon density of arboreal forests vegetation was 24.31 t/hm2 and below the national average; the young forests and middle-aged forests were dominant forest types, and accounted for 34.09% and 40.84% of total carbon storage, respectively; the vegetation carbon storage of natural forests and plantation forests were 35.123 5 million tons and 39.104 3 million tons, and their average carbon density was 26.72 t/hm2 and 22.49 t/hm2, respectively. Furthermore, the results also indicated that arboreal forests of Henan Province, especially plantation forests, will have the huge potential for carbon sequestration in the future, and will play an important role in forest carbon storage. |
