Abstract:

Due to the special climate, topography and hydrogeological conditions of Jianghuai hilly area, the insufficient water supply and the drought disasters occur frequently. Therefore, it is necessary to explore countermeasures to the drought disasters. The causes for drought and water shortage are discussed through analyzing the climate, topography, geology, soil, water conservancy project, social economy and human activities. The corresponding engineering measures and non-engineering measures were proposed. As the engineering measures, the investment in water conservancy infrastructure needs to be increased to improve the water storage-supply capacity of water conservancy project. As non-engineering measures, the planting structure should be adjusted, and the low yield soil should be improved according to situation, so as to enhance the soil water conservation ability, develop the water-saving and efficient agriculture and improve the capacity of drought resistance constantly.
