Assessment on Rough-Set Theoryfor Lake Ecosystem Health Index
Ruiqing Du · Journal of Biomathematics · 2008
The paper chooses phytoplankton biomass(BA)ect.5 ecosystem health index to classification,through calculating ecosystem health index(EHI)and determining synthesis weighting factors based on data from 30 lakes in Italy.Using rough-set theory to select and treat to 5 ecosystem health index,and calculating synthesis weighting factors and classification.The results showed that zooplankton biomass(BZ)has no effect on lakes healthy classification;Rough- set theory combined with healthy index have an important function.
