主　　题：Surface air temperature Warming trend Variations Ratio 

摘      要：Global warming and its climatic and environmental effects have mainly been investigated in terms of the absolute warming *** attention has been paid to the contribution of absolute warming rate to variability on various time scales of surface air temperature(SAT),which may be a more direct index for measuring the ecoclimatic effect of warming *** present study analyzed the role of secular warming trend in the variations of global land SAT for 1901–*** than one-third of annual SAT variations were contributed by the warming trend over large parts of the globe *** ratios were up to two-thirds over eastern South America,parts of South Africa and the regions around the southwestern Mediterranean and Sunda islands where the absolute warming rate was moderate but the endemic species were undergoing exceptional loss of *** ratios also exhibited smallest seasonal difference over these ***,the ratio of the warming trend to the SAT variations may be a better measure compared to the absolute warming rate for the local *** should also pay more attention to the regions with high ratio,not only the regions with the high absolute warming rate.
