| 摘 要： | 根据中国物候观测网络17个站点的物候资料和气象资料,分析了近40a中国东部地区木本植物秋季叶全变色期变化及其对气候变化的响应。结果表明:近40a,中国东部地区木本植物秋季叶全变色期变化总体表现为推迟的趋势,推迟的幅度为3.7d.(10a)-1;从年代上看,20世纪80年代后木本植物叶全变色期的推迟趋势明显;最低气温每升高或降低1℃,植物叶全变色期平均推迟或提前约3d;气候增暖可能是导致植物叶变色期推迟的主要原因之一。结果对丰富物候与全球气候变化关系研究具有重要意义。

| Abstract: | Based on plant phenological data from 17 stations of the Chinese Phenological Observation Network of Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences and the meteorological data,the change of autumnal leaf coloring of woody plants in Eastern China for the last 40 years was analyzed.The results showed that in Eastern China,the timing of leaf coloring change of the woody plants showed an average delaying rate of 3.7 day per 10 years,and this delaying trend was remark... |
