摘　　要：为了科学保护和合理利用岩滩水库的水域资源,采用指标体系法对岩滩水库的生态系统健康状况进行评价。结果表明,调查期间岩滩水库健康状况的季节变化总趋势为冬季>春季>秋季>夏季,空间变化总趋势为上音屯>汉达>巴龙岛>江栋,整体生态系统的健康状况为中等;生态系统的健康指数(EHI)和营养状态指数(TSI)呈显著负相关(P<0.05)。To make use of and protect the water resource of Yantan Reservoir reasonably and scientifically,index system was employed to evaluate the ecosystem health status in Yantan Reservoir. Results：The health status in different season displayed a decreasing trend spatially as follows：winter〉spring〉autumn〉summer;the health status in different aquatorium of Yantan Reservoir displayed a decreasing trend spatially as follows：Shangyintun〉Handa〉Balongdao〉Jiangdong;The health status of the whole reservoir is medium roughly;There were significant negative correlations between EHI and TSI （P〈0.05）.
