Abstract:

The Huaihe River and Huaibei of Anhui Province were the winter wheat main planting area. For real-time and dynamic monitoring the winter wheat, The EOS/MODIS data set from 2005 to 2010, which used as the main remotely sensed data. The combining comprehensive model of crop's monitoring based on NDVI change vector and trapezoidal area were constructed, the cloudless NDVI time of series image was reconstructed by HANTS and planting area of winter wheat was extracted in Anhui Province. The winter wheat crop was quantitative analyzed in the study, area with years of crop's annual change in time and space. The results showed that: the influence of lack of cloud and data were effective eliminated by Hants. The crops growth tread of change was clear reacted after reconstructed. The comprehensive monitoring model of NDVI change vector and Trapezoidal area analysis was more suitable for single growth season's growing remote sensing monitoring and the good monitoring result was obtained in 2011.
