Abstract
The construction of hydrogeological cities in China has attracted attention from researchers worldwide. This study surveyed the major urban hydroecological river channels and selected 59 stations for hydroecological field sampling. The Ecopath model was used to screen for key river species, and niche analysis was performed to study the niche breadth and overlap between the key species and water quality factors. Sixteen key fish species were screened out; Pseudorasbora parva had the highest niche breadth (2.952). Of the 16 screened key species, Carassius auratus had the largest niche overlap (11.977). Seven key zooplankton species were screened out. Phryganella nidulus had the highest niche breadth (2.070). Of the seven screened key species, P. hemisphaerica had the largest niche overlap (9.065). Of the nine screened key species, Bithynia fuchsiana had the largest niche overlap. These findings provide a reliable theoretical basis for ecological restoration, and serve as a methodological reference for sustainable water resources management.
