摘 要：正 The chaotic behavior of monthly precipitation time series is investigated using the phase-space reconstruction technique and the principal component analysis （PCA） method. A hydrological time series, monthly precipitation time series of 50 years （with a total of 600 values） observed on hills in middle region of Si Chuan, China, is studied. Delay time of monthly precipitation time series τ=5 is calculated by autocorrelation function method.
