Research on Drought Retrieve in Baiyangdian Basin, China

Abstract

Abstract Driven by global warming and human activities, the frequency, intensity and duration of drought have all showed an increasing trend. Most of the research on drought are only based on observed records, which cannot represent the natural evolution law of drought. Drought retrieve is of great importance to rational allocation of water resources in both social-economic system and natural ecological environment. This paper established the general framework of drought retrieve and did case study in Baiyangdian Basin, China. The Baiyangdian Basin of China has been suffering from severe drought in the recent years. Under the same precipitation and surface water resources condition, retrieved water flowing into the Baiyangdian wetland is much larger than the actual amount of inflow.
