The Ecosystem Ecology and Soil Biology Group has been conducting research on the interrelationships of multi-trophic levels in ecosystems for over 40 years. Their main research areas include grassland ecosystem ecology, ecological restoration, soil ecology and resource utilization. The group is a high-level, characteristic, and innovative group composed of young and middle-aged academic backbones with outstanding interdisciplinary features and complementary advantages. The group consists of two professors, one associate professor, one lecturer, and one postdoctoral fellow. Since 2000, they have published nearly 200 papers in mainstream domestic and international journals such as Nature, Science, PNAS, and Ecology, as well as more than ten monographs. They have undertaken more than 40 research projects, including national key R&D programs, "973" projects, basic special projects of the Ministry of Science and Technology, public welfare industry special projects of the Ministry of Agriculture, as well as key projects and general projects of the National Natural Science Foundation of China and the Seventh Framework Agreement of the European Union.
Currently, the group is undertaking seven research projects, including the National Key R&D Program of China "Smart Restoration and Synergistic Enhancement of Ecological and Production Functions in Meadow and Grassland Ecosystems and Demonstration", which has a budget of 16 million RMB; the Ministry of Science and Technology's Special Survey on Basic Scientific Resources "Investigation of Soil Animal Diversity in Eastern China's Agricultural Regions", which has a budget of 14.86 million RMB; the International Cooperation Project of the National Natural Science Foundation of China "Maintenance Mechanism of Biodiversity in Grazing Ecosystems with Multiple Trophic Levels: A Study Based on Cascade Effects", which has a budget of 1.97 million RMB; and the National Natural Science Foundation of China General Project "Geographical Patterns, Restrictive Mechanisms, and Sensitivity to Global Warming of Nordenskiöld's Love Worm Populations in Cold and Humid Forests of Northeast China's Middle and High Latitudes", which has a budget of 560,000 RMB.
代表性成果
1.多样化家畜放牧对生态系统多功能性作用及调控
该研究明确了多样化家畜放牧管理（即包含牛羊等多种家畜的混合放牧方式）提高草地生物多样性，进而促进草地生态系统的多功能性。进一步研究证明：在放牧家畜强烈干扰的草地生态系统中，保护草地多营养级的生物多样性，即保护包含地上植物、昆虫、以及地下土壤微生物和线虫的生态系统多样性，对维持生态系统多功能的重要意义。
2.家畜放牧对草地节肢动物食物网影响及互惠机制
该研究揭示了家畜采食通过调节生境结构而对蜘蛛和蝗虫的行为产生影响，最终改变蜘蛛-蝗虫捕食关系的机制。研究成果有助于深入理解放牧草地的虫害爆发机制，并为草地生态系统的放牧管理措施制定及生物多样性保护提供科学依据
3.气候变暖和不同土地利用方式对土壤微食物网结构和功能的调控机制
本研究以土壤微生物和线虫群落为研究对象，基于稳定同位素技术，揭示气候变暖和土地利用方式对土壤微食物网的影响机制，有助于反映全球气候变化对地下生态过程的影响，以及对地上地下相互作用关系的影响有重要科学意义。
4.基于集合群落的土壤动物物种共存研究
本研究将Leibold 提出了集合群落理论的4个经典范式，即斑块动态理论、物种分配理论、中性理论和集群效应理论，应用于土壤动物群落构建研究领域，解决多空间尺度土壤动物空间分布模式与驱动机制等问题。
