摘要:

蒙古国是蒙古高原的重要组成部分,是全球生态环境变化的重要响应区域。基于TIMESAT平台,运用MOD13Q1产品中的归一化植被指数(NDVI)数据,利用动态阈值法获取蒙古国植被物候参数信息,即春天NDVI值达到上升过程中NDVI变化振幅的50%时,判定植物进入返青期;秋天NDVI值下降至NDVI变化振幅的55%时,判定植物进入枯黄期。生长季长度即植被从返青期到枯黄期的天数。数据结果表明,2001-2019年,蒙古国多年平均的植被生长季长度为90-207 d。数据集内容包括2001-2019年逐年和多年平均的蒙古国植被返青期(SOS)、植被枯黄期(EOS)和植被生长季长度(LOS)的数据。数据集空间分辨率为250 m,存储为.tif格式,由60个数据文件组成,数据量为944 MB(压缩为3个文件,844 MB)。基于该数据集的研究论文发表在《地理研究》2021年40卷11期。数据论文
