摘　　要： 为评价东江干流(惠州段)生态系统健康状况,根据2011—2012年间该河段15个采样点采集的鱼类数据(参照点3个,观测点12个),通过对人类干扰的反应、指标分布范围、指标间相关性和判别能力分析,对常用的21个鱼类完整性指标进行了筛选,构建了东江干流(惠州段)鱼类完整性指标体系,并据此评价了15个取样点的健康状况。结果表明,东江干流(惠州段)15个取样点的健康状况有半数以上为亚健康及亚健康以上水平,其中,27%为健康,27%为亚健康,27%为一般,其余的19%为差。 Fish samples were collected from 15 sampling stations（3reference stations and 12 observed stations）in the Main Dongjiang River（Huizhou Reach）from 2011 to 2012in order to evaluate ecosystem health of Dongjiang River（Huizhou）.Through the analysis of response to human disturbance,distribution,correlation and discrimination ability,the authors selected the commonly 21 fish integrity indices used to construct the fish integrity index system of Dongjiang River（Huizhou）,and evaluate the health situation of the 15 sampling points.The results showed that 27% of the sampling points were healthy,27% were sub-healthy,27% were general in health,and the remaining 19% were poor in the 15 sampling points.
