利用青海省2000～2009年的气候资料和Miami模型,分析了青海省气温和降水的变化及天然草地植被初级生产力,结果表明:青海省2000年至2009年平均温先逐渐、后下降;Miami复合模型更适合计算青海省天然草地植被初级生产力.%Climate data of Qinghai from 2000 to 2009 and Miami model were applied to analyze the changes of average temperature and the net primary productivity of the natural grassland. Results showed that the average temperature was raising first and then decreasing. The complicated Miami model is more appropriative to estimate the net primary productivity of the natural grassland in Qinghai.
