中文摘要：
利用地面植被物候和1982~2003年遥感归一化植被指数（NDVI）数据,监测了中国东部南北样带植被春季物候变化情况。结果表明：（1）样带大部分地区植被春季物候期变化与年份相关性不显著;（2）春季物候期发生显著变化的地区均呈现提前趋势;（3）物候期年际波动幅度高于10 d的地区主要分布在以农业植被、常绿植被、草原植被覆盖为主的地区;（4）不同植被类型的春季物候期呈现一定时空变化规律。
英文摘要：
NDVI based on NOAA/AVHRR from 1982 to 2003 are used to monitor variable rules for the growing season in spring of vegetation in the north-south transect of eastern China（NSTEC）.The following,mainly,are included：（1）The changing speed of greenness period in spring of most regions in NSTEC is slow and correlation with the year is not distinct;（2） The regions in which greenness period in spring distinctly change mainly presented an advance;（3） The regions in which inter-annual fluctuation of greenness period in spring is over 10 days were found in 3 kinds of areas： the area covered with agricultural vegetation types;the areas covered with evergreen vegetation types;the areas covered with steppe vegetation types;（4） changes of vegetation greenness period in spring have spatiotemporal patterns.
