Understanding the relationship between integrated landscape patterns (coupled land use, soil properties, and topography) and stream water quality in different seasons promotes appropriate landscape planning. However, this relationship is unclear. Here, water quality nitrogen (N) and phosphorus (P) levels and the integrated landscape patterns were investigated in ten Chinese subtropical catchments during 2010 & ndash;2017, using the least absolute shrinkage and selection operator (LASSO) regressions method and redundancy analysis (RDA). The results suggested that stream water N and P levels wer...
