摘　　要：对大兴安岭地区及其周围8个气象站点年降水量和年平均气温进行反距离权重插值,并代入Thornthwaite Memorial模型来估算1990年和2010年大兴安岭地区的植被净第一性生产力,获得这两项气候因子及植被净第一性生产力空间分布图,进一步对其动态变化及空间分布情况进行分析。We use the method of Inverse distance weighted interpolation to interpolate the annual precipitation and annual average temperature of eight meteorological stations in Daxingan mountain. Then we use the Thornthwaite Memorial model to estimate the vegetation net primary productivity of 1990 and 2010 in Daxingan mountain and get the two climate factors and vegetation net primary productivity spatial distribution map, further the dynamic changes and spatial distribution were analyzed.
