摘　　要：为解决大王滩水库底泥淤积治理的问题,需全面了解水库各区域底泥情况,调查库区底泥的深度、数量、污染程度和分布区域。通过对大王滩水库底泥中的重金属元素及营养盐、水质富营养化、水生生物的分析,揭示其空间分布特征,采用潜在生态风险指数、水生生物丰富度指数和水质全指标分析相结合的方法对库区底泥污染程度、区域分布等方面进行评价。In order to solve the sediment problem of Dawangtan Reservoir,it is necessary to investigate the sediment situation of various reservoir zones including the sediment depth,quantity,extent of pollution and range of distribu⁃tion.Through the analysis of heavy metal elements and nutrient salt,water eutrophication,aquatic organisms in the sediment of Dawangtan Reservoir,the spatial distribution characteristics were revealed;the pollution extent and dis⁃tribution of sediment in the reservoir were evaluated by analysis of potential ecological risk index,hydrobios rich⁃ness index and all water quality indicators.
