Spatial-temporal variations of river water quality under human-induced land use changes in large river basins.

ABSTRACT: Land use patterns and anthropogenic activities exert diverse impacts on river water quality and ecosystem health across spatial and temporal scales. Under ongoing pressures from human activities and climate change, it is urgently needed to understand the pollution mechanisms and associated ecological risks in surface waters through cross-basin assessments that incorporate a broad set of water quality parameters. This study investigated the spatial-temporal variations of 22 water quality parameters, including physico-biochemical indicators, nutrients, and heavy metals, at 39 sampling sites across the Daliao River (DLR), Shuangtaizi River (STR), and Naoli River (NLR). Field observations were conducted in September 2019, December 2020, and June 2020, covering the wet, dry, and agricultural se
