摘要The scaling and multifractal properties of drought conditions of different regions in China were explored by employing multifractal detrended fluctuation analysis. Results show that the long-range correlation of the drought series in northern China is stronger than that in southern China, and that scaling properties vary at different time-scales. The scaling behaviors of the drought series in all of the regions are separated by a common crossover time-scale of around 1.5 years. The three regions of north China, southwest China, and the Yangtze River basin exhibited an additional crossover at a 9-year scale. The drought time series are stationary and long-range correlated at a time-scale of 1.5 years in all the regions and at a time-scale longer than 9 years in northern China, southwest China, and the Yangtze River basin. They are however non-persistent at a 1.5-to-9-year scale. Meanwhile, the h(q) curves indicate that the drought series are multifractal.
