近30年中国不同土地覆被类型的地表气温变化
Surface Air Temperature Changes of Different Land Cover Types in China during 1979-2007
摘要
Abstract
The surface air temperature changes of different land cover types in China were investigated by using observation minus reanalysis （OMR） method. The OMR trends for the 1979-2007 period were estimated from NCEP/NCAR Reanalysis 1 and surface observation temperature monthly data, which showed that China had an overall OMR warming trend of 0.18℃/10a. The OMR trends with respect to different land cover types were analyzed based on AVHRR land cover classification data. The results show that the sensitivity of surface air temperature to different land cover types is different. Most of the land types show positive OMR trends, while forests show negative trends. OMR results with land type under different thresholds are quite similar, which indicates the robustness of this method.关键词
