摘要/Abstract

摘要： 研究满足水质和水量需求的生态流量对于河湖水环境治理保护很有必要。以水质性缺水的河流举水新洲段为例,基于实测河道断面数据和污染源调查结果,运用MIKE11软件建立了河道水量水质模型,并根据实测资料对模型进行了率定。利用率定后的模型,以COD、NH₃-N、TN、TP作为主要污染物指标,通过试算法计算了现状排污条件下,各月份中控制断面水质达标的生态流量,同时运用Tennant法和流量频率曲线法计算了满足河流生态系统基本水量需求的生态流量。对3类方法计算结果综合比较讨论,得出了统筹水质水量的举水新洲段各月份生态流量。

Abstract: The governance and protection of lake and river water environment require the consideration of both the quantity and quality of water to preserve ecological flow. In this study we examine the Xinzhou segment of the Jushui River, a tributary of the Yangtze River, using the MIKE11 software to develop a water quantity and quality model. The model was calibrated using measured data and data from pollution source investigations. The model measured the main pollutants including COD, NH₃-N, TN, and TP, and established the water demand for control sections to meet water quality standards on a monthly basis with consideration of current sewage discharge levels. In addition, we utilized the Tennant method and flow frequency curve method to calculate the ecological water demand to ensure the basic stability of the river ecosystem. By comparing and analyzing the results of Tennant method, flow frequency curve method, and the proposed model, we obtained the monthly ecological water flow for the Xinzhou segment of Jushui River.

Key words: ecological flow, MIKE11 software, Tennant method, flow frequency curve method, Xinzhou segment of Jushui River
