[Objective]Under the background of global warming,this paper focuses on the study of the regional responsive variation characteristics of climate and drought-flood around the Bohai Sea,to make out the disaster prevention and mitigation policy,and to improve the ability of drought and flood disasters strain. [Methods]On the basis of the temperature and precipitation data of 60 meteorological stations located around the Bohai Sea from 1961 to 2012,using the linear trend method,Mann-Kendall mutation test and spatial interpolation method,we attempted to reveal the spatial-temporal variations characteristics of climate;regional drought and waterlogging were graded using the Zindex and then the temporal-spatial responses of them were elucidated.[Results] (1) It had experienced an apparent trend of climate warming and drying in the region around the Bohai Sea.The warming rate was 0.25℃/10a.In the years of 1988 around,an abrupt temperature rise occurred.The warming rate had small and insignificant difference between the north and south of that region although the temperature between the two sub-regions was significantly different. (2) Precipitation had witnessed a decreasing trend with a rate of 10.37 mm/10a.From southeast to northwest,from coastal regions to inlands,precipitation decreased spatially while differences of the temporal decreasing rate among the sub-regions was small. (3) After 1988,frequency of drought-flood disasters showed an apparent increasing trend around Bohai Sea.Drought occurred more frequently than flooding and more sub-regions underwent drought over than waterlogging around the Bohai Sea.Overall,the region had an obvious trend of drought.[Conclusion]The climate in the region around the Bohai Sea had responded to global climate change.Especially,drought and flood disasters showed a regional style.
