The tidal river network area has the characteristics of criss-crossed water systems and developed cities. High intensity land use and development leads to serious hydrological pollution and degradation of ecological environment functions of urban landscape lakes. Taking the typical urban landscape lake in the river network area - Baiyun Lake in Guangzhou as the research object, this paper constructed a two-dimensional hydrodynamic and water quality coupling model to study its eco-environmental water demand and its water supplement schemes. The results show that the two-dimensional hydrodynamic and water quality coupling model in the river network area based on Mike21 can effectively simulate the temporal and spatial evolution law of water quality in urban landscape lakes, and the relative errors between the simulated values and the measured values are less than 0.20, Nash efficiency coefficients are greater than 0.75. By jointly using Baiyun Lake sluice and pump hydraulic engineering to dispatch and replenish water, the assurance rates of eco-environmental water demand of Baiyun Lake and its connected rivers are basically 100%, the contents of TN and TP meet the fourth class water quality. The research results can provide reference for ecological and environmental governance of urban landscape lake of polluted river network.

感潮网河区水系交错、城市发达,高强度土地利用开发导致城市景观湖泊水环境污染严重,生态环境功能退化。以典型网河区城市景观湖体—广州市白云湖为例,构建二维水动力水质耦合模型,研究其生态环境需水及其补水方案。结果表明,基于MIKE21的二维网河区水动力水质耦合模型,能较好模拟城市景观湖泊水体水质输移规律,模拟值与实测值相对误差值均小于0.20,纳什效率系数均大于0.75;运用白云湖闸、泵水利工程联合调度补水,白云湖及其连通水系生态环境需水量保证率基本达到100%,TN及TP浓度均达到Ⅳ类水标准。研究成果可为感污河网区城市景观湖泊生态环境治理提供参考。

感潮网河区水系交错、城市发达,高强度土地利用开发导致城市景观湖泊水环境污染严重,生态环境功能退化。以典型网河区城市景观湖体—广州市白云湖为例,构建二维水动力水质耦合模型,研究其生态环境需水及其补水方案。结果表明,基于MIKE21的二维网河区水动力水质耦合模型,能较好模拟城市景观湖泊水体水质输移规律,模拟值与实测值相对误差值均小于0.20,纳什效率系数均大于0.75;运用白云湖闸、泵水利工程联合调度补水,白云湖及其连通水系生态环境需水量保证率基本达到100%,TN及TP浓度均达到Ⅳ类水标准。研究成果可为感污河网区城市景观湖泊生态环境治理提供参考。

The tidal river network area has the characteristics of criss-crossed water systems and developed cities. High intensity land use and development leads to serious hydrological pollution and degradation of ecological environment functions of urban landscape lakes. Taking the typical urban landscape lake in the river network area - Baiyun Lake in Guangzhou as the research object, this paper constructed a two-dimensional hydrodynamic and water quality coupling model to study its eco-environmental water demand and its water supplement schemes. The results show that the two-dimensional hydrodynamic and water quality coupling model in the river network area based on Mike21 can effectively simulate the temporal and spatial evolution law of water quality in urban landscape lakes, and the relative errors between the simulated values and the measured values are less than 0.20, Nash efficiency coefficients are greater than 0.75. By jointly using Baiyun Lake sluice and pump hydraulic engineering to dispatch and replenish water, the assurance rates of eco-environmental water demand of Baiyun Lake and its connected rivers are basically 100%, the contents of TN and TP meet the fourth class water quality. The research results can provide reference for ecological and environmental governance of urban landscape lake of polluted river network.
