英文摘要	Inter-annual variations of precipitation play important roles in forest management and agricultural production. This study presents a 270-year precipitation reconstruction of winter to early growing season for the central Lesser Khingan Mountains, Northeast China based on tree-ring width data of 99 tree-ring cores of Korean pine from two sampling sites near Yichun city. The reconstruction explained 46% of the variance in precipitation from the previous October to current June during the calibration period CE 1959-2017. At decadal scale, we identified four dry periods that occurred during CE 1748-1759, 1774-1786, 1881-1886 and 1918-1924, and four wet periods occurring during CE 1790-1795, 1818-1824, 1852-1859 and 2008-2017, and the period CE 2008-2017 was the wettest in the past 270 years. Power spectral analysis and wavelet analysis revealed cyclic patterns on the inter-annual (2-3 years) and inter-decadal (-11 and -30-60 years) timescales in the reconstructed series. In addition, the Asian polar vortex has an important effect on the precipitation in our study area.
