| 摘 要： | 利用1982-2006年NOAA/AVHRR归一化植被指数(NDVI)时间序列,结合植被、地形和气候等资料,研究新疆植被活动的年际变化及其季节差异.结果表明:过去的25年,占新疆植被面积27%的地区生长季(4～10月)NDVI显著增加(P＜0.05),其中近一半地区年增加速率大于0.003,而显著减少地区的面积仅占4%...

| Abstract: | Interannual and seasonal variations of vegetation activity in Xinjiang during the period from 1982 to 2006 were studied using the time series data of normalized difference vegetation index (NDVI) derived from remote sensing images (NOAA/AVHRR),information of vegetation distribution and observed climatic data. The results show that the NDVI in growth season (from April to October) increased significantly in 27% of the study area but decreased in 4% of the study area in recent 25 years. The area with a high N... |
