| 摘 要： | 利用S-G(Savitsky-Golay)滤波对2000—2016年呼伦贝尔市境内的大兴安岭植被NDVI序列进行逐栅格重构并剔除突变点,结合大兴安岭海拔、坡向、坡度等地理因子和气温、降水等气象因子,分析大兴安岭植被生长季NDVI的变化及其对气候的响应。结果表明:大兴安岭植被NDVI生长季均值呈上升趋势,平均增速为0. 029/10 a。植被NDVI随海拔的增加呈现先缓慢减小后迅速增加的趋势,随坡向变化不大,随坡度的增加而增加。植被NDVI的生长季均值与1 a前和2 a年前的降水呈现显著的正相关,具有明显的滞后性。在每年植被恢复生长初期各海拔植被均与气温呈现极显著的正相关,年内植被NDVI与降水的相关性在垂直方向上存在较大差异。
