基于3种富营养化评价方法的锦江河水质风险评估
Risk Assessment of Water Quality in Jinjiang River Based on Three Nutrient Enrichment Evaluation Methods
摘要
Abstract
Taking Jinjiang River in Tongren City as an example,the physicochemical indicators of the water body were collected and analyzed.Three methods,Carlson's trophic state index(TSI),modified trophic state index(TSIM)and trophic level index(TLI),were used to evalu-ate the nutrient enrichment level in Jinjiang River water.Mathematical statistical analysis was used to examine differences between the different evaluation methods and the influence of environmental factors on them.The results showed that different evaluation methods lead to different re-sults in eutrophication assessment of water bodies.According to TSI,TSIM and TLI evaluation methods,the results of Jinjiang River water body were assessed as having oligotrophic,eutrophic and mesotrophic conditions,respectively.Single-factor analysis of variance showed that a significant difference between TSIM and TSI/TLI(P＜0.05),while no significant difference was observed between TSI and TLI(P＞0.05).Correlation analysis showed Chl-a was significantly positively correlated with TSI and TSIM(P＜0.05),while TN and TP were significantly positively correlated with TLI(P＜0.05).TSI and TSIM mainly characterized the growth status of algae,while TLI focused more on nitrogen and phosphorus levels.Overall,compared to TSI and TSIM methods,TLI adopted a weighted approach of multiple environmental factors,which could more scientifically reflect the eutrophication status of water bodies.关键词
