lizardWelcome to the LEES Lab

The LEES Lab at the CGCEO of Michigan State University, directed by Dr. Jiquan Chen, is interested in scientific investigations and education on fundamental ecosystem and landscape processes for understanding ecosystem functions and management.

Our current studies are focused on the carbon and water cycles of different ecosystems (grassland, desert, forest, cropland, wetlands, freshwater) at multiple spatial and temporal scales, bioenergy systems and resource uses, coupled interactions and feedback between climatic change and human activities, and sustainable management and conservation.

Our research projects, spreading mostly across North American and Asian landscapes, are based on sound field experiments and monitoring stations, state-of-the-art equipment and technology, modeling, and remote sensing technology. The LEES Lab is also the home of book series on "Ecosystem Science and Applications—ESA" for the Higher Education Press (HEP) and MSU Press. We maintain a high ethical and liberal standard for professional collaborations in research and education.

Figure 1. Calculations of the intermediate variables and IMoSES from six input variables using the algorithms of Equations
(3)–(5). Historical data during 1992–2016 from Inner Mongolia (IM) and Mongolia (MN) are used to illustrate the changes
of input variables, intermediate variables and IMoSES. Because of the large differences between the two jurisdictions,
independent vertical axes are used for MN (leftmost labels, blue) and IM (rightmost labels, grey). The vertical axes are
scaled for easy visualization of the changes over time.
