摘要
河流生态水位是维系河流生态系统的基本要素。本文根据周山河的水文资料、水力参数、水生生物种类等情况,采用水文学法、水力学法和生境法3种方法分别计算周山河生态水位,通过Tennant法评价后,综合考虑平原河网地区水文情况和泰州市水利工程引排能力等因素,结合周山河水情特点、用水实际和水位现状等,最终推荐周山河的生态水位。该研究成果可为周山河生态水位目标优化和调控保障提供技术支撑,为周山河水资源保护、水生态修复和未来开发利用提供科学依据。
The ecological water level of river is the basic factor of maintaining river ecosystem.In this paper,according to the hydrological data,hydraulic parameters and aquatic organisms of Zhoushan River,the ecological water level of Zhoushan River is calculated by using three methods,namely,hydrologic method,hydraulic method and habitat method.After the evaluation by Tennant method,the hydrological situation of plain river network area and the drainage capacity of Taizhou water conservancy projects are considered comprehensively.The ecological water level of Zhoushan River is finally recommended by combining the characteristics of water situation,actual water use and current water level.The research results can provide technical support for ecological water level target optimization and regulation guarantee of Zhoushan River,and provide scientific basis for water resources protection,water ecological restoration and future development and utilization of Zhoushan River.
