GIS division emphasizes on both geospatial techniques such as geo-sensor data collection, precise point positioning with GNSS, geo-processing and geospatial analysis, multidimensional data visualization and their applications in field survey, environmental modeling and resource management. The development on these aspects takes full advantage of an integrated solution of open source and proprietary geospatial toolkits based on open interoperability standards. Recent research topics and grant-in-aids from three faculty members include "visual mining methods of multidimensional spatial information" and "geo-processing workflow of WebGIS" supported by National Natural Science Foundation of China, "generating a routable road map from vehicle GPS traces" by Knowledge Innovation Program of the Chinese Academy of Sciences, "dynamic decision supporting system for coal-bed gas surface gathering" and “3D Pollution Diffusion Simulation System For Three Gorges Reservoir Basin” by National Science and Technology Major Project of the Ministry of Science and Technology of China.

    The ecological research at CRE currently focuses on three fields: (1) Effects of climate change on ecological processes; (2) Plant's life-form strategies; (3) Landscape pattern, processes, and dynamics. Specifically, the research objects at CRE include: (1) Response of carbon cycling in grassland ecosystems to climate change (2) Emission characteristics and controlling of greenhouse gases in grassland ecosystems; (3) Plant's ecophysiological aspects of climate change; (4) Underground ecological processes and controlling mechanisms; (5) Spatial analysis and scale issues; (6) Dynamic simulation of grasshopper meta-population; (6) Structure and function of urban riparian buffer; (7) Carbon-water cycling processes modeling; (7) Plant's water-use strategies; (8) Drought severity assessment. The current research projects include: (1) Carbon and water cycling processes at multiple scales (NSFC); (2) Multi-scale pattern-process interactions among urban land use, riparian zone structure, and transfer of nitrogen and phosphorus in river (NSFC); (3) Comparison of plasticity in water-use strategy between Leymus chinensis and Stipa grandis (NSFC); (4) Warming effects on formation and stability of soil organic-mineral complexes in Kobresia humilis meadow – micro-scale study (project of CAS "Knowledge Innovation Program"); (5) Potential relationship between spatial pattern of stomata and plasticity of stomatal density (project of CAS 'knowledge innovation program); (6) CH₄ and N₂O Emission from northern temperate meadow steppes of China (project of CAS "Strategic Priority Research Program").

 The research field mainly focuses on the following four areas: (1) the coupling of carbon and nitrogen cycles in the terrestrial ecosystems and its responses to global change such as elevated atmospheric nitrogen deposition and CO2 concentration enrichment. (2) the effects of environmental changes on biodiversity, community structure, and carbon sequestration in the terrestrial ecosystems.（3）the application of stable carbon and nitrogen isotope techniques in global change ecology and（4）the modeling and simulation of processes and functions in the terrestrial ecosystems in the scenarios of global change. Presently, the above studies are funded by the National Key Research and Development Program, titled “the effects of increased atmospheric nitrogen deposition on key processes of carbon and nitrogen cycles in an alpine meadow on the Qinghai-Tibaten Plateau” (2010CB833502), National Natural Science Foundation of China, titled “responses of soil nitrogen immobilization, transformation and loss to low level nitrogen input in an alpine meadow on the Qinghai-Tibaten Plateau”  ( 31070435), Fund of Key Laboratory of Agricultural Environment and Climate Change of Ministry of Agriculture, titled “the early effects of elevated CO2 concentration on soil carbon dynamics in the rhizosphere of soybean-wheat rotation system ”, etc.
