英文摘要 | The sensitivity of surface air temperature response to different grassland types and vegetation cover changes in the regions of temperate grassland of china was analyzed by observation minus reanalysis (omr) method. the basis of the omr approach is that reanalysis data are insensitive to local surface properties, so the temperature differences between surface observations and reanalysis can be attributed to land effects. results showed that growing-season air temperature increased by 0.592 a degrees c/decade in the regions of temperate grassland of china, with about 31 % of observed warming associated with the effects of grassland types and vegetation cover changes. for different grassland types, the growing-season omr trend was the strongest for temperate desert steppe (0.259 a degrees c/decade) and the weakest for temperate meadow (0.114 a degrees c/decade). our results suggest that the stronger intraseasonal changes of grassland vegetation are present, the more sensitive the omr trend responds to the intraseasonal vegetation cover changes. in august and september, the omr of temperate meadow showed a weak cooling trend. for temperate meadow, about 72.2 and 72.6 % of surface cooling were explained by both grassland type and increase of vegetation cover for august and september, respectively. for temperate steppe and temperate desert steppe, due to the limited soil moisture and little evaporative cooling feedback, the vegetation changes have no significant effect on the surface air temperature. these results indicate that the impact of grassland types and vegetation cover changes should be considered when projecting further climate change in the temperate grassland region of china. |
