Against the backdrop of global warming, assessing effects climate change on hydrological processes is crucial for local water resource management. Variations in temperature, precipitation, and runoff at four different timescales Fuhe River Basin were evaluated based observational data collected from 1960 to 2020 using Mann–Kendall test. The findings indicated significant increases average temperatures annual, flood season, non-flood season periods, rising by 0.0197, 0.0145, 0.0278 °C every annum, respectively (p < 0.01). Precipitation exhibited non-significant upward trends all > 0.1). trend was also non-significantly upward, whereas annual displayed downward Flood temperature decreased with increasing altitude, exhibiting a Pearson correlation coefficient −0.744 0.01 level. Conversely, flood, precipitation significantly increased coefficients 0.678 level, 0.695 0.558 0.05 significance respectively. similar throughout year, initially then decreasing over time, reaching maximum values June. Climate likely responsible alterations study basin. could provide references management decisions Basin.
