Agriculture Drought Risk Assessment of the Irrigated Agriculture Zone in North Henan Plain Using HJ-1 and MODIS data
This paper analyzed the evolution of drought and the spectral response of the crop at different growing seasons focuses on the irrigated agricultural areas of northen Henan using the HJ-1 data and MODIS data,associated with relevant meteologic data, regional geographical data and the social economic data.The Spatial and temporal distribution of the risk of disaster-causing factors and the fragility of the disaster-affected body was conducted and the comprehensive index of agricultral drought risk was built up.Then, trend of the agricultural drought was analyzed and the irrigated agricultural drought risk class was performed and the possible hazard and influence of agricultural drought and the performance of appropriate strategy to reduce agricultral drought have been estimated.At last,verification of the results and improvement of the model have been carried out supported by the historic cases, expert system and the on-site investigation data.
