The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论:(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征,研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强,年GPP总量为652.2 gC/m~2,明显高于其他三种生态系统;通过利用"单塔日变化法"获得四站点通量观测数据随机误差,结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征,与正态分布相比,更服从双边指数分布,进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化,这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设,因此本研究中引入最大似然法进行生态过程模型参数优化。
