Rice is a primary food crop, and rice production ensures security maintains social stability with great significance. Flooding paddy fields as an important step in affects the entire growth process of rice. The selection flooding time highly correlated yield water resource utilization. In background global warming, early high-latitude planting areas can ensure that has sufficient growing to increase yield. However, overly may cause waste resources due insufficient heat. Currently, research on timing relatively lacking, monitoring temperature during particularly deficient. To respond climate change, it necessary explore whether current schedule meets actual needs. Based MODIS surface reflectivity data, we identified First Day (FFD) Peak (PFD) Sanjiang Plain. Using Land Surface Temperature (LST) data meteorological station-provided air analyzed corresponding LST for PFD from 2008 2024. main conclusions are follows: (1) both FFD Plain have trend advancing year by year, showing stronger advancement than FFD; (2) show downward year; (3) 2024, generally met needs next production. This study first attempts use high-temporal-resolution remote sensing images identify achieve timely changes temperature.
