| 摘 要： | 基于1982-2003年间GIMMS发布的NOAA /AVHRR遥感数据和新疆自治区53个地面国家标准站点的气象数据,研究新疆归一化植被指数(NDVI)动态变化及其与气候的时空关系.结果表明,22 a间新疆植被NDVI年际变化总体上呈显著增长趋势,年平均增长率为0.59%,显著增长区域位于准噶尔盆地南缘和塔里木盆地西南缘;生长季、夏季和秋季NDVI与同季降水相关显著,春季、秋季NDVI与同季温度相关显著;NDVI与温度呈显著正相关的区域主要分布于阿尔泰山、天山和昆仑山等山区,与降水呈显著正相关的区域分布于平原、低山带和绿洲.

| Abstract: | Based on the 1982-2003 NOAA/AVHRR remote-sensing data published by GIMMS and the meteorological data of 53 natural meteorological stations in Xinjiang Autonomous Region during the period of 1982-2003,dynamics of NDVI and its temporal and spatial correlation with climate was studied.Results show that within the 22 years,annual variation of NDVI generally displayed a significant rising trend,with an annual mean rising rate of 0.59%,particularly in areas along the southern fringe of the Dzungaria Basin and the... |
