| 摘 要： | 利用1982—2000年的NOAA/AVHRR逐旬数据，采用最大变化斜率法、曲线拟合法等方法分析黄淮海地区植被生长季开始及结束时间，选取典型样带，制作基于逐像元的INDV(归一化植被指数) 变化图，研究1982—2000年植被生长季的变化规律及其对气候变化的响应。结果表明:黄淮海地区生长季开始的平均时间为3月下旬，结束时间为11月上旬。20年来研究区植被四季平均INDV呈上升趋势，春季增长尤为显著，且随着年代的推移，植被生长季有延长的趋势，生长季提前是黄淮海地区植被活动对气候变化响应的主要方式。

| Abstract: | Using the each ten-day data of NOAA/AVHRR from 1981 to 2000 and adopting the Maximum-Slope method,Curve-Fitting method and stepwise regression,the beginning and ending of the growth season of the vegetations in the Huanghe-Huaihe-Haihe(HHH) region are analyzed.Meanwhile,the pixel by pixel I_(NDV) map is worked out with typical bands as the sample.Through analyzing the change of green wave and brown wave,the changing rules of vegetation activities and its responses to climate changes in the past 20 years are... |
