Abstract

Root turnover is a key process of terrestrial ecosystem carbon cycle, which is of great significance to the study of soil carbon pool changes and global climate change. However, because there are many measurement and calculation methods of root turnover, the results obtained by different methods are quite different, and the current research on root turnover of forest ecosystem on the global regional scale is not sufficient, so the change law of root turnover of global forest ecosystem is still unclear. By collecting literature data and unifying the calculation method of turnover rate, this study integrates the spatial pattern of fine root turnover of five forest types in the world, and obtains the factors affecting fine root turnover of forest ecosystem in combination with soil physical and chemical properties and climate data. The results showed that there were significant differences in fine root turnover rate among different forest types, and it gradually decreased with the increase of latitude; the turnover rate of fine roots in forest ecosystem is positively correlated with annual average temperature and annual average precipitation; fine root turnover rate of forest ecosystem is positively correlated with soil organic carbon content, but negatively correlated with soil pH value. This study provides a scientific basis for revealing the law and mechanism of fine root turnover in forest ecosystem.

森林生态系统细根更替规律及其影响因素
根系周转是陆地生态系统碳循环的关键过程,对研究土壤碳库变化和全球气候变化具有重要意义。然而,由于根系周转量的测量和计算方法较多,不同方法得到的结果差异较大,目前在全球区域尺度上对森林生态系统根系周转量的研究还不充分,因此全球森林生态系统根系周转量的变化规律尚不清楚。本研究通过收集文献资料,统一周转率的计算方法,整合世界五种森林类型细根周转量的空间格局,结合土壤理化性质和气候数据,得到森林生态系统细根周转量的影响因素。结果表明:不同林型间细根周转率存在显著差异,随纬度的增加而逐渐降低;森林生态系统细根周转率与年平均气温、年平均降水量呈正相关;森林生态系统细根周转率与土壤有机碳含量呈正相关,与土壤pH值呈负相关。本研究为揭示森林生态系统细根更替的规律和机制提供了科学依据。

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.
