摘　　要：针对三峡水库河道型水库的特点,初步建立了Chl-a与各营养物的回归关系模型,运用相关加权综合营养状态指数法对水库进行评价,并与湖库富营养化评价方法的评价结果相比较,其结果均为贫营养。但同湖库富营养化评价方法相比,基于河道型水库综合营养状态指数法的评价结果偏低。当水体稳定后,用相关加权综合营养状态指数法对多种因子进行综合评价,能够比较真实地反映水体营养状况。The regression relationship between chlorophyll-a and nutrients was determined based on the characteristics of the river channel component of the Three-Gorges Reservoir. The nutrient level of each region was evaluated by the weighted correlation of the comprehensive nutrient index. The results were compared with those base on assessment method for lake-water eutrophication. The results of the assessment based on channel type reservoir are lower. The correlation weighted comprehensive nutritional index with multiple -factor can more truly reflect the nutritional status.
