Dr. Jan Janse gave an oral presentation at the FES, Sept. 26, 2016.

 

On Sept. 26th, 2016, Dr. Jan Janse from the Netherlands Environmental Assessment Agency (PBL) and the National Institute of ecology (NIOO), together with Dr. Annette BG Janssen from the Netherlands Wageningen University and NIOO, paid a visit to Institute of Hydrobiology, Chinese Academy of Sciences (IHB). During their visit, they attended the 6^th Freshwater Ecology Seminar of IHB where they discussed issues related to the theme "Nutrient and Lake Management". This FES was chaired by Dr. Wang Haijun, Associate Professor of IHB. 

Dr. Janse first gave an oral presentation with the title of "The development of the Lake model PC Lake and its application for water management in the Netherlands". He emphasized the importance of ecological modeling when dealing with the restoration and management problems of polluted water, and then he went down with the established PC Lake model to explain the ecological structure of the model. He pointed out the issues of complexity of ecological modeling, and further explained the newly established global model which combined the PC Lake model and a variety of social factors and some other parameters. At last, he introduced some successful cases of the model application in the Netherlands and other countries and he also listed the limitations of the model’s application. 

Dr. Janssen then gave an oral presentation with the title of "Ecosystem modeling of large shallow lakes: Taihu as a case study". She pointed out that due to the lack of a clear and reliable management target, the environmental and social problems caused by eutrophication failed to be solved effectively. She called for the establishment of quantitative model to give reliable advice for wastewater treatment. In her presentation, she took China's Taihu Lake as an example to introduce their work, in which their team used PC Lake model and Deltft3D hydro-dynamic model to evaluate the water quality of Taihu Lake. The models combined the spatial heterogeneity of cyanobacteria blooms to assess the impacts of eutrophication on Lake water quality. They also gave some suggestions on lake’s quantitative management. 

After the presentation, the attendees had in-depth discussion on the spatial scale of ecological modeling.  

The FES was held to motivate young scientists to study the philosophy of science and methodology and promote exchanges and cooperation between them. This seminar was jointly organized by the Research Center for Freshwater Ecology and the CAS Youth Innovation Promotion Association.
