Recently, Ecology Letters, the world's leading ecological journal, published the paper with the title of “Allometry of fine roots in forest ecosystems”by Professor Chen Guangshui , as the first author from School of Geographical Sciences of the University, and Professor Chen Guangshui and Professor Yang Yusheng as the co-authors. The paper is about the relationship between the fine roots and allometric growth of forest ecosystems. The collaborators include Professor Sarah Hobbie and Professor Peter Reich from the University of Minnesota,, and Professor David Robinson of the University of Aberdeen, England.
Although forest fine roots only account for a small proportion of biomass, they have a rapid turnover and consume 1/3 of the net primary production per year. They play an extremely important role in forest carbon and nutrient cycling, and thus become an important parameter in various ecosystem models. However, the current estimation of fine root production in forests still lacks a theoretical model. Our school researchers applied the pipe model to the underground part of the forest, proposed the allometric growth relationship between the fine root biomass and the production volume, and verified the relationship using the existing database. The results provide a way for the theoretical prediction of forest fine root biomass and production, and promote the theoretical understanding of the relationship between forest allometric growth and forest underground carbon distribution.
Ecology Letters is one of the top journals in the field of international ecology. It is a journal of natural index sources (one of five journals in the field of environmental science and ecology) with a five-year average impact factor of 11.775. With only over 100 papers published every year, the academic competition caused by it is extremely fierce worldwide In the past 20 years, Chinese scholars have published nearly 30 papers in this journal, which is the first time for our university to publish articles in this journal.
