On the assessment method based on correlation weighted comprehensive nutritional index in the Three Gorges Reservoir

摘要

Regression models between the chlorophyll a and other nutrient factors were established elementarily for the characteristic that the Three Gorges Reservoir is a channel reservoir.The nutritional quality of water body was assessed using correlation weighted comprehensive nutritional index.The result was compared with that of assessment based on the nutrient status index of lakes in order to make it closer to the actual environment and embody the feasibility of this method to assess nutrient status in the channel reservoir.
