Based on the monthly precipitation data for the period 1960–2008 from 616 rainfall stations and the phenology data of main grain crops, the spatial characteristics of drought hazard in China were investigated at a 10 km×10 km grid-cell scale using a GIS-based drought hazard assessment model, which was constructed by using 3-month Standard Precipitation Index (SPI). Drought-prone areas and heavy drought...
In this study, the spatial characteristics of agricultural drought vulnerability in China were investigated using a GIS-based agricultural drought vulnerability assessment model, which was constructed by selecting three agricultural drought vulnerability factors. Seasonal crop water deficiency, available soil water-holding capacity and irrigation were identified as the main indicators of agricultural...
