Evaluation of Nutrient Status in the Mainstream and Tributaries of Three Gorges Reservoir
摘要
Abstract
In order to reflect the overall eutrophication conditions of the mainstream and tributaries of Three Gorges Reservoir since 175m water level impoundment operation of reservoir,the eutrophication status of above water body are evaluated by using comprehensive nutrition state index (TLI) method according to water environmental monitoring data in recent years.The results show that the nutritional status of mainstream of Three Gorges Reservoir is mesotropher,the TLI of upstream tributaries is overall high and the eutrophication level is eutropher,and the eutrophication level of downstream tributaries is mesotropher.Among four typical tributaries,the TLI of Xiangxi River is generally high and the eutrophication level is eutropher in most of year,the TLI of Shennongxi River is increasing and reaches a critical state of eutrophication,the TLI of Daning River is less than 50 and the utrophication level is mesotropher,and the TLI of Xiaojiang River reaches mesotropher occasionally but there is a slight decreasing trend.关键词
