项目摘要

中文摘要

申请人近年来致力于土壤微生物呼吸对温度、降水及多因子协同变化的响应行为和微生物调节机制方面的研究,原创性研究结果主要有:1) 揭示了土壤微生物呼吸的温度驯化现象与微生物群落结构变化的关系;2)发现升温可放大降水量与[CO2]增加对土壤微生物呼吸和净初级生产的刺激效应,而降水量与[CO2]增加的刺激效应则相互抑制;3) 发现降水量增加对土壤微生物呼吸的刺激效应可被降水季节分配变化和降水强度增加所抵消;4)开发了一个新的模拟源汇生态系统间枯落物生产、分解与转移的MELT模型。申请者目前担任landscape Ecology等3份英文期刊的编委,同时任F1000 Prime的评审专家。共发表论文57篇,其中SCI论文22篇。近5年在Soil Biology & Biochemistry,Global Change Biology等主流期刊发表SCI论文12篇,总计他引61次,单篇最高他引31。

英文摘要

My research in recent years is mainly focused on the responsive behaviors of soil microbial respiration to global environmental changes and the underlying microbial regulation mechenisms. My major academic contributions include: i) Establishment of the linkages between the thermal acclimation of soil microbial respiratoin and microbial community structure; 2) ii) Warming could amplify the stimulating effects of precipitation and [CO2] increases on soil microbial respiration (Rh) and net primary productivity (NPP), whereas precipitation and [CO2] increases could counteract their individual effects; iii) Changes in precipitation seasonal distribution and event density could ameliorate the stimulating effects of increasing precipitation amount on Rh, suggesting that precipitation seasonality and density are also important aspects of precipitation pattern change; iv) Development of a new mechanistic model (MELT) that simulates litter transformation and transfer processes within and between source and sink ecosytems. I am a faculty member of F1000 Prime and serve on the editorial board of three international journals such as Landscape Ecology. I have published 57 papers and 22 of them are in SCI journals. In the recent 5 years, I have published 12 SCI papers in the main-stream ecological journals such as Global Change Biology and Soil Biology & Biochemistry. These papers have been cited for 61 times in total and the mostly-cited one has received 31 citations.
