摘要
河道生态需水量是河流生态系统健康的重要保障。随着社会经济的发展,浑河生态系统的健康受到威胁。以受流域水资源开发利用影响较大的浑河中下游河段作为河道生态需水量研究的重点区域,采用月保证率法和鱼类生境法计算中下游河道不同等级的生态需水量,通过Tennant法验证了计算成果的合理性。最终确定了浑河中下游河道最小、适宜和理想等级生态需水量,并分析了浑河河道生态需水量的特征。
Ecological water requirements （EWRs） are the important guarantee for the health of river ecosystem. With the rapid development of social economy, the health of Hunhe River ecosystem is threatened seriously. The key study area of EWRs is the middle and lower reaches of Hunhe River, which is influenced by the exploitation and utilization of water resources. The monthly guaranteed frequency method and fish habitat method are applied to calculate EWRs with different grades in the middle and lower reaches of Hunhe River. The rationality of EWRs results are verified though Tennant method. Finally, the minimum, medium and ideal grade of EWRs in the middle and lower reaches of Hunhe River are confirmed, and the characteristics of instream EWRs are analyzed.
