[Objective] The process of paddy field of cultivated land has a crucial impact on the quality of cultivated land. To clarify the spatial response of cultivated land quality to paddy field of cultivated land in northeast black soil area is an important prerequisite for improving the quality of black soil cultivated land and realizing the sustainable use of cultivated land. [Methods] LESA cultivated land quality evaluation system, CRITIC model and bivariate local spatial autocorrelation model were used. [Results](1)The phenomenon of paddy field of cultivated land in the study area was intense, showing the strongest spatial and temporal pattern in the east, followed by the west, and the weakest in the middle.(2)The quality of cultivated land in the study area had changed significantly, and the proportion of decline in cultivated land quality was lower than the proportion of quality improvement, showing a spatiotemporal pattern of the highest decline in the middle, the second highest decline in the west, and the lowest decline in the east.(3)The response of cultivated land quality to paddy field transformation in the study area had a dual effect, and the negative response was more sensitive. The overall response of cultivated land quality in the east was higher than that in other regions. [Conclusion] Paddy farmland in the study area has positive and negative effects on the quality of cultivated land. Adjusting the structure of cultivated land use according to the effect direction is an important way to protect black soil cultivated land. For areas with positive effects, the drought to water project should be moderately promoted, while for areas with negative effects, the drought to water project should be stopped, paddy field fallow should be actively carried out, and it can be properly restored to dry land.
