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。

The effect of Zea mays and Bromus riparius on soil and water loss were studied,the experiment was conducted to plant crop and grass in runoff-plots on the 15 degree slope naturally,the bare slop is CK,then the runoff and soil erosion amount and the biological characteristics of corn and meadow bromes termly were measured,and difference of soil and water loss prevention effect on the slop land were determined.The results showed that soil and water loss became less after both corn and meadow brome planting.And the leaf area and the coverage of meadow brome higher than corn,which was benefit for less soil and water loss at the rain season early.Meanwhile,roots of corn and meadow brome mainly distributed in 0-10 cm soil layer,and the root biomass of meadow brome was 2.88 times than that of corn.

试验在自然降雨条件下，在15°坡地设置作物与牧草径流试验小区，以裸地为对照，在每次降雨之后用全深剖面采样器取样，测量其径流量和土壤侵蚀量，定期测定玉米和草地雀麦的生物学特性，研究玉米与草地雀麦生物学特性变化及其坡地水土流失防治效果的差异，探索植物种植对坡地水土流失的主要影响因素，结果表明：种植玉米与草地雀麦，对坡地水土流失均有一定防治作用，但是，与玉米相比，草地雀麦的叶面积指数和覆盖度可在雨季前达到较高水平，有利于早期坡地水土流失防治。

And than the soil water contents of mountainous meadow was intervenient. The diversification of soil bulk density was completely reverse with the soil water contents. The soil bulk density of alpine meadow and sub alpine meadow was evidently lower than hilly meadow steppe and alluvial flat meadow steppe.

高山和亚高山草地类型的土壤含水量明显高于低山丘陵和河滩阶地的类型，而中山类型的草地土壤含水量在它们中间；土壤容重的变化趋势则完全相反，高山和亚高山草地类型的土壤容重明显低于低山丘陵和河滩阶地的类型。
