Abstract: The satellite data have been used to monitor the growth status of paddy rice. Because of the complex climate features, whether the method can be applied in Sichuan Basin remains unclear. In this study, the authors investigate the growth status of paddy rice in the western Sichuan plain by using composed ten-day NDVI sequence of SPOT data from 2001 to 2010. The results showed that, the seasonal variation of NDVI sequence of SPOT could accurately reflect the growing periods and the growth status of paddy rice in the western Sichuan plain: each growing period of paddy rice is corresponding to a certain NDVI value. The NDVI value was between 0.5 and 0.6 during the period of paddy rice reviving. The NDVI value reached its peak from the tillering period to stem extension period of paddy rice, up to 0.7-0.8. In booting and sprouting periods, the NDVI declined to 0.6. After that, it decreased rapidly, and was less than 0.4 during the milkripe and mature periods. Based on the results, it could be concluded that, the SPOT NDVI data could depict the growth status of paddy rice in the western Sichuan plain, and could use as one of potential data sources for monitoring the growth status of paddy rice.
