摘要

城市河网的连通性在城市用水安全、水质(WQ)和水生态平衡等诸多方面发挥着重要作用。本研究以北京市朝阳区的河网和马家湾湿地为研究对象,建立了一个二维水文水质模型,在河网和湿地之间采用了多种水量分配方案。以水循环和水质为主要指标,模拟并比较了不同方案对改善水循环和水质的影响。研究表明,与其他两个方案相比,在河网与湿地内部慢水区交汇处增加补水(方案 2)对改善水文和水质的效果更好。马家湾湿地水域面积扩大,水流速度加快。以化学需氧量、总氮、总磷为指标值确定水质级别,约 20%的湿地面积水质达到Ⅱ类水(生活饮用水),其余 80%达到Ⅲ类水(一般工业用水)。这项研究为类似地区的城市河网连通性提供了有价值的评估和参考。

Research on the connectivity of urban river network–wetland and water quality simulation
The connectivity of urban river networks plays an important role in cities in many aspects, such as urban water safety, water quality (WQ), and aquatic ecological balance. This study focuses on the river network and the Majiawan Wetland in the Chaoyang District of Beijing by establishing a two-dimensional hydrological WQ model employing various water allocation schemes between the river network and the wetland. Water circulation and WQ are the main indexes, and the effects of different scenarios on improving water circulation and WQ are simulated and compared. This study demonstrates that the addition of water replenishment at the intersection of river network and internal slow-water zones of the wetland (Scheme 2) has greater effectiveness in improving both hydrology and WQ compared to two other schemes. The water area of the Majiawan Wetland has expanded, and water velocity has increased. Using chemical oxygen demand, total nitrogen, and total phosphorus as the index values for determining the water class, the WQ of about 20% of the wetland area was reached Water Class II (domestic drinking water), with Water Class III (general industrial water) accounting for the other 80%. This study provides valuable evaluation and reference for similar areas of urban river network connectivity.
