China is undergoing rapid urbanization, which has brought great pressure on croplands throughout the country, especially in fast developing cities. In this study, we attempted to monitor and model the cropland dynamics of Hangzhou from 1990 to 2035.

Discussion and Conclusion

The modelling results reported that under PAES and OADS, the study area could gain 81.76 km2 and 255.14 km2 more cropland, respectively, than that under SS in 2035. Thus, policies applied in PAES and OADS would be effective for cropland protection.
