Variation of drought and regional response to climate change in Huang-Huai-Hai Plain

It is widely recognized that the frequency and intensity of extreme weather events and climate disasters have strongly increased with global warming. The area of influence of climate disasters has also increased, which has had adverse effects on sustainable social and economic development. Drought is a recurring natural phenomenon, and is associated with a deficit of water resources over a large geographic area and long duration. In this paper, we determine drought characteristics in all four seasons and the winter wheat growing season on the 3H Plain, together with the effects of climate change. Therefore, relevant agencies should create an early warning system of extreme weather events and natural disasters, toward improvement of future regional agricultural scientific management and decision support systems in agricultural production. These agencies should also adapt to climate change by selecting strongly drought-resistant crop varieties and by adjusting cultivation methods and management measures, especially irrigation measures aimed at spring drought on the 3H Plain.
