生态水文学在河口生态需水评价中的意义

In recent years, much attention has gradually been paid to environmental flow assessment for estuaries. Due to complex and multitude influencing factors, great challenges have been posed on environmental flow assessment for estuaries. Ecohydrology, integrating biological and hydrological process, was discussed as a scientific concept applied to problem-solving in environmental issues. An attempt, therefore, made here to reflect the advance and application prospect of ecohydrology in estuarine environmental flow assessment. Considering insufficient biological information of estuaries, simplified ecohydrology model by identifying the key aspects of estuarine ecosystem should be a significant tool in environmental flow assessment.
