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。

P in Shule River Alluvial Fan Oasis in Gansu subsidized by CNSF. Through field geological and environmental observations and sampling, quartz OSL dating, organic carbon ~(14)C dating, as well as analysis of TOC,grain size and Pollen assemblage of the samples from ten sediment profiles in front fine grain sediment zone of the Shule River Fan, the results obtained as follows:(1)The vegetation evolution history on Shule River Alluvial Fan and circumjacent since about 13 ka B.P. could be divided into 6 phases: about 12.1-13.1ka, a sparse coniferous and broadleaf trees - shrub grassland, cold and wet climate; 9.2-12.1ka, shrub grassland, temperature rising but precipitation and humidity getting down; 5.8-9.2ka, sparse forest with the most flourish shrub grassland under the optimal climate; 4.3-5.8ka, coniferous and broadleaf mixed forests -shrub grassland, temperature rising slightly and getting dry; 4.3-2.8ka, grass vegetation and climate became more dry; 2.8-2.3ka, coniferous forests -shrub grassland, precipitation and temperature getting down, but a higher relative humidity.
本文依托于&甘肃疏勒河冲积扇5万年来古天气环境与古水文演化&项目，以疏勒河冲积扇为研究对象，通过对疏勒河冲积扇扇缘细土带全新世古天气和古水文演变进行了20余个剖面的观测和取样、石英OSL和~(14)C测年、粒度组成和TOC分析以及孢粉鉴定，获得了以下成果和熟悉：(1)距今约13ka年来冲积扇和周边植被演化经历了6个阶段：约13.1～12.1ka，以针叶林为主的针阔混交林～灌丛草原，天气冷湿；12.1～9.2ka，灌丛草原，气温升高，降水量较低；9.2～5.8ka，疏林灌木草原，植被茂盛，温度和降水最佳；5.8～4.3ka，以针叶树为主的针阔混交林～灌丛草原，气温较高，降水减少；4.3～2.8ka，草原植被，天气变干；2.8～2.3ka，针叶林～灌木草原，降水减少，温度降低，相对湿度有所增加。
