To evaluate the wind erosion climatic erosivity and its response to regional climate change in Northeast China, based on the weather data at the 66 meteorological stations in Northeast China from 1981 to 2019. The spatio-temporal characteristics of wind erosion climate erosivity and its response to climate change were analyzed by using the calculation method proposed by FAO. The results showed that in the past 39 years (1981—2019), the wind speed and relative humidity in Northeast China showed the downward trends, the precipitation showed a fluctuating increase trend, and the temperature showed an increasing trend. The overall trend of wind erosion climate erosivity was high in the west and low in the east, with a spatial average of 18.8 and a spatial range of 0.9 to 63.8. The wind erosion climatic erosivity in spring, summer, autumn, and winter were 10.4, 1.4, 4.1, and 2.9, respectively. The annual wind erosion climatic erosivity in the whole region decreased by 3.71 per decade on average, and decreased by 2.05, 0.24, 0.96 and 0.44 per decade in spring, summer, autumn and winter, respectively. The wind erosion climatic erosivity had obvious spatial character (high in the west and low in the east) and seasonal character (high in spring and low in summer). In the past 39 years, the annual and seasonal wind erosion climatic erosivity all showed the downward trends. This study provides theoretical basis for soil wind erosion control in different agricultural planting areas.
