Chen Jun, Professor
Education:
B.S.Inner Mongolia Universityfor the Nationalities, Grassland Science 1988
M.S. Ibaraki University,Japan, Grassland Ecology 2004
Ph.D Ibaraki University, Japan, Grassland Ecology 2007
Research Interests:
My interests in research are, first, to diagnose degraded grassland vegetation in the northwest arid China. The diagnosis is essential to recovery and productionof grasslands. A method developed by us, based on statistical ecology, for surveying and analyzing vegetation will be useful for this research. Second, my interest is to develop new theoretical and practical methods to field surveys of grassland vegetation. I am also interested in modeling grassland ecosystems to manage the productivity and conservation.

Outreach and Extension:
A cooperative research project with the National Ibaraki University (Japan) (Faculty of Science, Ecology Laboratory) was started in 2008. The foci of the project are: (1) Researches on recovery of degraded grasslands in northwest arid districts in China, and (2) Study on statistical ecology of spatial heterogeneity in grassland plant communities. I presented papers at the Annual Congress of Ecology (the Ecological Society of Japan), and the Annual Congress of Japanese Society of Grassland Science in 2009 and 2010. I participated in and presented a paper at the 21th International Grassland Congress held at Huhhot, Inner Mongolia, China, in 2008.
