The MOD13A3 EVIproducts,forest inventory data and tree ring data were used to estimateANPP of Piceacrassifolia in nature reserve of Qilian Mountainby the regression model.The performance of i EVI in estimating ANPP was improved after the quality weighted S-G method. The annual forest ANPP showed a fluctuant increasing trend from 2000 to 2013 in the nature reserve of Qilian Mountain.Furthermore,the ANPP increased from the northwest to the southeastern and the annual average ANPP was 51.34 ~ 274.24 g·m~(-2). ...
0引言森林地上净初级生产力ANPP(aboveground net primary production)是地表碳循环的组成部分,准确估测森林ANPP的变化是全球碳循环研究的重要内容.树木年轮数据具有分辨率高、时间序列长等优势[1],能获取长时间序列的森林ANPP,但在大尺度森林ANPP估测方面存在局限.MODIS数据?
