Abstract EN
China is considered to be one of the most drought prone countries.
This study is dedicated to analyzing the regionalization and spatiotemporal variations of drought based on the Standardized Precipitation Evapotranspiration Index, which covers the period 1961–2013 across 810 stations in China.
Using Spatial “K”luster Analysis by Tree Edge Removal method, China was divided into eight regions: southwest (SW), northeast (NE), north (N), southeast (SE), Yangtze River (YR), northwest (NW), central China (C), and Tibet Plateau (TP).
The spatiotemporal variations of drought characteristics indicated that the drought count in NE and C was generally high.
Southern China and NW had suffered long drought duration and extreme severity.
The MK test results show that stations with significant drying trends mainly locate in SW, N, NW, and C.
The severe drought frequency was very high in 1990s and 2000s.
Furthermore, more attention should be paid to abnormal less precipitation in summer and abnormal high temperature in spring in SW, NE, N, and C.
Besides, abnormal less precipitation is the main factor of drought in SE and YR in whole year.
This study is anticipated to support the water resources management, and to promote the realization of environmental protection and agricultural production.
