In the context of climate change, the escalating frequency of global precipitation fluctuations amplifies uncertainties in assessing the impact on forest ecosystem productivity. Hence, elucidating the dynamic relationship between precipitation characteristics and forest growth can provide effective management strategies for addressing climate change. This study characterizes the frequency and amplitude of precipitation fluctuations and analyses the response of forest growth from 1982 to 2022 in Northeast China. The research findings indicate that: (1) the growth of 13.7% of the region's forest is declining, with 8.1% of the area showing significant degradation; (2) the core degradation zones for forest growth are located in semi-arid regions with precipitation frequencies ≥ 12 and amplitudes ≤ 60 mm and subhumid regions with precipitation frequencies ≥ 14 and amplitudes ≤ 65 mm; (3) in the core semi-arid zone, deciduous broadleaf shrublands have greatest degraded area (2.8×10 4 ha), but deciduous needleleaf forests have the highest proportion of degradation (57.1%), while in the subhumid core degradation zone, deciduous broadleaf forests have the highest area (1.7×10 5 ha) and proportion of degradation (9.3%). This study not only provides a novel perspective for evaluating forest ecosystem responses to precipitation characteristics, but also offers crucial theoretical support for advancing the implementation of Nature-based Solutions in practical applications.
