The northern fringe of East Asian summer monsoon (EASM) includes the west side of Great Khingan Range, southeastern of Inner Mongolia Autonomous Region, northern of Hebei and Shanxi Provinces and the Ordos Plateau. During historical periods, fluctuations in the intensity of EASM have caused multiple drought and flood events in this region. By employing the database of 9 high resolution tree-ring width chronologies and the Palmer Drought Severity Index (PDSI) grid data neared the locations of chronologies, the present study aims to analyze the extreme drought events from 1740 A.D. to 1999 A.D. in the northern fringe of EASM. By means of statistical methods,we also calculated the fractions of the chronologies exceeding each of critical values (including mean value (i.e., 0), 1 time standard deviation departure to the mean value (i. e., 1SD), and 2 times standard deviation departure to the mean value (i. e., 2SD)) which indicate the fractions of those chronologies with extreme drought events recorded,and analyzed the intensity and affected areas of each extreme drought event. The areal mean tree-ring series show that over the past 260 years the northern fringe of EASM has experienced multiple drought events, which include the periods from 1890 A.D. to 1894 A.D.,1898 A.D. to 1905 A.D.,1926 A.D to 1932 A.D., and 1991 A.D. to 1997 A.D. In addition, the statistics results show that over the past 260 years there were variations in the temporal and spatial trends of each extreme drought events : the extreme drought event occurred from 1890 A.D. to 1894 A.D. was recorded in some chronologies with significant low values (i.e., <-1), but it was not recorded by the other chronologies, indicating that although the areal mean series did depict this drought event, its influences were limited within some areas; the extreme drought event occurred from 1898 A.D. to 1905 A.D. had been recorded by most of available tree-ring chronologies (over 70% of the available chronologies),suggesting it influenced most of the study area; the extreme drought event occurred from 1926 A.D. to 1932 A.D., which was marked by nearly all of the chronologies (over 90% of the available chronologies) with abnormal low values,was an exceptional and the most intensive and extensive climate disasters over the past 260 years in this region; the drought event occurred from 1991 A.D. to 1997 A.D. was recorded by 60% of the available chronologies, and beyond 50% of these recorded chronologies showed abnormal low values (i. e., < -1),which demonstrates that although this drought event spread a limited areas, its affected areas was dominated by extreme dryness.
