利用树轮资料和植被指数估测青海云杉林地上净初级生产力
Estimation of Piceacrassifolia forest aboveground net primary productivity from tree ring data and vegetation index
摘要
Abstract
The MOD13A3 EVIproducts, forest inventory data and tree ring data were used to estimate-ANPP of Piceacrassifolia in nature reserve of Qilian Mountainby the regression model.The performance of iEVI 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 AN-PP was 51.34~274.24 g·m-2. The ANPP of Piceacrassifoliawas positively correlated with precipitatio-nand temperature. Compared with the temperature, the precipitation is main factor affecting the change of ANPP.关键词
