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).
