Understanding the spatial patterns and driving mechanisms of net primary productivity (NPP) precipitation utilization efficiency (PUE) is crucial for assessing ecosystem services. This study analyzed variations in NPP PUE Heilongjiang Province from 2001 to 2020, using MOD17A3 products meteorological, topographic, land use data. The distribution seven categories was determined study, namely, cropland, forest, grassland, water, barren, impervious wetland. multi-year averages were 428.96 gC·m−2·a−1 0.74 gC·m−2·mm−1, respectively, with forests showing highest values barren lands lowest. During period, 91.4% increased at an average rate 3.36 gC·m−2·a−1, while exhibited a polarized trend. Changes use, especially conversions involving cropland along climatic factors such as rising temperature, significantly influenced dynamics. These findings provide scientific basis ecological restoration assessment function under changing conditions.
