Abstract: | Drought is the uppermost natural disaster in the Hebei Plain, which during the past 20 years showed a trend of frequency increasing, range extension, longer duration and severer damage. In the Hebei Plain, as a major grain producing area, the agricultural drought emergency relief can only rely on groundwater exploitation. Thus the work to conduct evaluation of groundwater supply capacity for agricultural drought emergency relief of Hebei Plain is of great significance for disaster prevention and relief. In this paper, with the method of analytic hierarchy process, the evaluation index system with reference to 3 aspects and 7 indexes (the former including groundwater resources, groundwater exploitation technical conditions and water supply facilities) and the ArcGIS Desktop ArcMAP software, the work to assess the shallow groundwater supply capacity for agricultural drought emergency relief in the Hebei Plain was carried out. |
