Understanding precipitation changes over a long period of time can provide valuable insights into global climate change. Taking the forest–steppe ecotone North China as research area, based on tree ring width index Carya cathayensis Sarg (Carya cathayensis), relationship between growth and factors is analyzed, annual reconstructed from data nearest five weather stations AD 1540 to 2019. The results show that trees was affected by in precipitation. divided three dry periods wet 480 years, wavelet analysis. There were 328 years within mean plus or minus one standard deviation (SD) (accounting for 68.3% years), indicating relatively stable conditions exist study which has become main agricultural areas China. Each lasted 2–7 according multi-taper method, change closely related El Niño–Southern Oscillation (ENSO) short scale Atlantic Multidecadal (AMO) medium during 60–80
