Focuses the researches on a eutrophication model after drainage of waste water and drawing water from the Qiantang River to the West Lake,the state variables in the model are phosphorus in algae cells,orthophosphate,phosphorus in detritus and phosphorus in sediment.

This paper divides the lake eutrophication models into the single factor load model,the phytoplankton and nutrient salts related model and the ecological dynamics model,introduces basic characteristics of the three kinds of models,and probes into the developing trends of lake eutrophication model.

The influence of algae type eutrophication on aquatic higher plants and hydrophytic vegetational reconstruction in Taihu Lake;

Under the low temperature (8℃)and suitable temperature(28℃),the poor mediumand rich medium were adopted,64 strains were isolated from soil in rape root system of our institute.

Application of matter element analysis method to water quality eutrophication assessment of lakes;

Relative distance measure model for eutrophication comprehensive evaluation of lake;

The key scientific problems in lake eutrophication studies;
