土壤生态研究组简介

        中国科学院西双版纳热带植物园土壤生态研究组建于2003年,隶属于中国科学院热带森林生态学重点实验室,在第一任组长邹晓明博士(任期2003-2010年)的带领下,研究组科研人员及研究生在热带、亚热带和温带森林生态系统开展了土壤微生物生态学、生物地球化学循环过程、土壤碳氮循环机制等热点科学问题的研究,在国际上具有影响的土壤学期刊如Soil Biology and Biochemistry, Applied Soil Ecology等发表多篇论文,为版纳植物园土壤生态组的稳定发展奠定了基础。

        2012年5月,杨效东研究员担任研究组组长,在已有研究基础上,研究组将以我国西南地区热带、亚热带温带森林系统为主要研究对象,通过理论、实验及野外调查相结合的方法,探讨生物多样性的维持机制及其生态系统功能。研究主要涉及:热带、亚热带森林生态系统节肢动物(昆虫)和土壤生物群落结构和多样性对环境变化的响应机制;土壤生物重要功能群对养分转化和碳固持、释放的影响;昆虫、土壤生物与地上植物的协同进化和时空异质性关系;碎屑食物网结构和功能以及不同营养级功能群(或物种)的相互反馈作用机制;外来土壤生物(如蚯蚓)的发展变化(维持、排斥和入侵)和入侵驱动因素;植物根圈效应与土壤微生物、土壤线虫、地上植物的相互关系等。

    Soil Ecology Group of Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences was set up in 2003. It is a part of Key Laboratory of Tropical Forest Ecology. Under Dr. Zou Xiaoming’s (as PI from 2003-2010) leadership, researchers and graduate students conducted a study of microbial ecology, biogeochemical cycling, soil carbon and nitrogen cycling mechanism and other hot issues of science in tropical, subtropical and temperate forest ecosystems, laying the foundation for the development of XTBG soil ecology group.

In May 2012, Prof YANG Xiaodong became the research group leader. Based on the previous study, our group use tropical, subtropical and temperate forest system in the southwest region of China with the main research objective to explore the mechanisms of biodiversity maintenance and ecosystem function through theoretical, experimental and field survey method. Research mainly involves: response mechanism of tropical and subtropical forest ecosystems arthropods (insects) and soil organisms community structure and diversity to environmental change; effects of important functional groups of soil biological on nutrient transformation, carbon sequestration and release; interactions between spatial and temporal heterogeneity and co-evolution of insect, soil organisms and aboveground plants; Detrital food web structure and function, interaction mechanisms of different trophic levels of functional groups (or species); driving factors of invasion of exotic soil organisms (such as earthworms); relationship between plant rhizosphere effect and soil microbes, nematodes.
