摘要:
气候变化下植被的时空响应是近年来的研究热点。高海拔西藏地区气候独特多变,研究该区域植被与气候变化的关系具有重要意义。西藏地区的气象站少,利用站点观测资料插值分析误差相对较大,难以准确获得空间连续的数据。本文采用2001~2013年MODIS卫星16天时间序列数据和同期的降雨卫星TRMM数据,利用线性回归和相关性分析法研究西藏地区植被、地表温度和降雨量的时空特征及相关性。研究表明:在2001~2013年间,西藏地区植被与地表温度、降雨量在时间波动和空间分布上具有一致性。植被NDVI逐年增大,植被状况逐渐改善,地表温度总体呈上升趋势,降雨量整体无明显变化,三者年际变化率主要集中在-0.005~0.005/a,-0.05℃~0.15℃/a,-30~40mm/a。近13年来植被NDVI、地表温度和降雨量的变化区域差异性较大,在西藏中部和东部变化明显。植被NDVI的变化与气候变化(尤其是地表温度上升)密切相关,受降雨明显影响的区域分布在西藏中部,受地表温度明显影响的区域分布在西藏东部和西部。
