In order to define the characteristics of the trend variation and the temporal-spatial distribution of the extreme climate events in Liaoning Province in recent 50 years,23 meteorological stations in the province are selected on the basis of the data of the annual daily mean temperature,lowest temperature,highest temperature and precipitation from 1964 to 2015,while 8 extreme temperature indexes and 4 precipitation indexes adaptable for the study area are chosen in accordance with the Climate Change Detection and Index confirmed by the World Meteorological Organization (WMO),and then the temporal-spatial evolution characteristics of the extreme temperature and precipitation events in Liaoning Province in recent 50 years are analyzed herein with linear trend method,Mann-Kendall mutation test and inverse distance weighted interpolation method. The result shows that from temporal scale,the characterizing extreme high temperature events,such as extreme high temperature,day number of summer, day numbers of both warm day and warm night,are to be gradually increased with continuous increasing trends in a period of time in the future and all the indexes of the extreme low-temperature events,i. e. number of frost days,number of cold days, and number of cold nights,present the variations of decreasing trends,while all the extreme precipitation indexes exhibit increasing trends except the more smooth precipitation intensity of common day,thus the extreme precipitation events in Liaoning Province are increased. On the spatial scale,the extreme highest temperature,lowest temperature,frost days,day number of summer show the laws of descending from the north to the south,while cold nights,cold days,warm nights and warm days show the irregular distributions. The extreme precipitation indexes related to precipitation show the patterns of high in the south and low in the north as well as high in the east and low in the west.
