中国东部季风区植被物候季节变化对气候响应的大尺度特征:年际比较

         

摘要

The annual variations in different phases (the whole year, growing season, the increasing and declining parts of growing season) of the phenological responses to climate change in East China were determined with the normalized difference vegetation index (NDVI) data set of the NOAA/NASA Pathfinder AVHRR data sets from 1982 to 1993.Two results were obtained from the analyses.(1) Either in multi-year average or in each year the variations of seasonal phenology and those of temperature were synchronous, the latter stably driving the former.(2)In each year, the response of seasonal phenological growing to rainfall change existed, though there were variations in the correlations and the relevant lag between them. The quantitative analyses of such responses will be conducive to improving the vegetation growing description in land surface process models, and therefore enhancing the capability to simulate the interannual climate variations in East China.%利用1982~1993年NOAA/NASA Pathfinder AVHRR陆地数据集中的NDVI数据集,在中国东部植被生长的不同阶段(全年、植被生长季、植被生长季的增长阶段和衰退阶段),对植被季节生长对气候响应的年际变化进行了分析,发现:(1)无论在多年平均意义上还是逐年来看,中国东部季风区植被季节性生长状况对温度的响应在各个生长阶段都是近于同步的,温度对于植被生长季节变化的驱动关系非常稳定;(2)逐年来看,植被季节性生长对降水的响应也是存在的,但相关关系和相关的滞后关系具有年际差异。通过定量化地分析中国东部植被季节生长对季风气候响应的年际变化,有助于对陆面过程模式中的有关部分进行改进,从而提高对中国东部区域年际气候变化的模拟能力。
