利用1963—1988年中国木本植物物候观测资料,运用趋势分析的方法研究了26 a来全国21个站的木本植物物候变化特征。结果表明:26 a来,全国各地区木本植物春季物候期和秋季物候期大体上都是推迟的,1976—1988年与1963—1975年相比,绝大多数植物物候期都有明显推迟,部分植物物候期推迟了10 d以上。
In this paper,we use woody plants phenological data from 1963 to1988 throughout China and trend analysis method to analyze woody plants phenology variation characteristics of 21 stations.The results prove that the spring phenophase and autumn phenophase of woody plants are generally delayed in all regions.Compared data from 1963 to 1975 with that from 1976 to 1988,it was found that the majority of plants phenological events has been significantly delayed,for some plants the delay could reach more than 10 days.
