腾格里沙漠南缘哈思山树轮记录的NDVI变化
腾格里沙漠南缘 树轮 NDVI 干旱气
2018/4/16
利用采自腾格里沙漠南缘哈思山的油松树轮样品建立树轮宽度年表，结合GIMMS归一化植被指数（NDVI）数据资料重建了本区1804~2009年6~9月NDVI变化序列。本研究分析了NDVI序列变化特征，在此基础上，探讨了本区植被变化与沙尘暴天气及其与干旱气候的关系，结果表明：近206年来腾格里沙漠南缘NDVI虽未发现显著增加趋势，但期间经历了多次波动；植被生长较好的阶段出现在1826~1829年、18...
An exponential relationship between net primary productivity (NPP) and integrated NDVI has been found in this paper. Based on the relationship and using multi-temporal 8 km resolution NOAA AVHRR-NDVI ...
NDVI changes in China between 1989 and 1999 using change vector analysis based on time series data
2007/8/24
Abstract: Change vector analysis (CVA) and principal component analysis in NDVI time-trajectories space are powerful tools to analyze land-cover change. The magnitude of the change vector ...
