Abstract

ABSTRACT Increased CO2 levels caused by human activities (e.g., fossil fuel consumption and deforestation) has become a major concern for climate change and caused environmental problems. Afforestation/reforestation can help mitigate CO2 emission in the atmosphere by sequestering atmospheric carbon (C) in tree biomass. Herein, the above- and below-ground C sequestration of two pioneer tree species, including Acer velutinum Bioss and Alnus glutinosa L plantation stands of 25 (A25) and 35 (A35) years old were studied. The mean annual growth of diameter at breast height (cm/year) was significantly higher in A35 than A25, while the mean growth of height (m/year) was significantly higher in A25. The total and mean annual growth of the tree biomass and C storage (root and trunk) was significantly higher in A35. The amount of soil C sequestration in A35 was also significantly higher than in A25. The above-ground C sequestration and the annual average of C sequestration of the trees were positively correlated with soil moisture, pH, nitrogen, and phosphorus. Our study illustrates the benefits of considering stand age in the growth and developmental patterns of forest ecosystems in estimating terrestrial C stocks.

枫树和桤木人工林固碳和土壤性质随林龄的变化

人类活动(如化石燃料消耗和森林砍伐)导致的二氧化碳水平升高已成为气候变化和环境问题的主要关注点。造林/再造林可以通过在树木生物量中封存大气中的碳(C)来帮助减少大气中的二氧化碳排放。以25年(A25)和35年(A35)树龄的绿槭(Acer velutinum Bioss)和桤木(Alnus glutinosa L)两种先树林分为研究对象，对其地上和地下碳的固存进行了研究。A35的胸径年平均生长量(cm/年)显著高于A25, A25的胸径年平均生长量(m/年)显著高于A25。A35的总生物量和年平均生长量、根和干碳储量显著高于其他树种。A35土壤固碳量也显著高于A25。树木地上碳固存量和年平均碳固存量与土壤水分、pH、氮、磷呈正相关。我们的研究说明了考虑林龄在森林生态系统生长和发育模式中对估算陆地碳储量的好处。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
