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。

After nest found, the dominating ecological factors with definite distance to nest tree (less than 10 meters) including tree species, tree height, habitat type of nesting-tree, nest position, the type of nesting tree branch, nest type, the type of nest-site, the viability status of tree and branch was described and measured. Geography coordinates (latitude-longitude) was converted into orthogonal coordinates, and add to Arcview3.2 as shape-file, and measured the distance between nest and the habitat type including double-line river, lake, seasonal lake, shallow mire, deep water mire, meadow mire, farmland, sparse forest, forest marsh, the boundary of Nature Reserve and road.

The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.

海拔4400～4600m的较低海拔地带退化最强烈，主要为高寒草甸与高寒沼泽草甸受牧业影响较大；牧业影响半径为24km；道路的影响范围为24km，道路的修建加速了人类对高原植被的破坏作用；阳坡植被呈现趋于稳定和退化的趋势，阴坡植被表现为增长的趋势，降水量增加是源区植被，尤其是阴坡植被变好的重要原因，而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因；近河床区地下水位埋深较浅，植被生长具有稳定的地下水源；在远离河床的一定区域内，地下水易于疏干，植被易于退化，河流影响范围为24km。

The plant community composition changed and the community coverage increased over the wetland succession from primary swamp, through swampy meadow, to meadow. The number of associated species increased, while the dominant species abundances decreased. Through succession, the content of soil organic matter and total nitrogen declined. In contrast, the soil enzyme activity of catalase, protease and invertase increased; however urase declined.

随着湿地原生沼泽向沼泽化草甸、草甸的演替，湿地植物群落盖度增加、物种组成增多，群落优势种优势度减小，伴生种数量增加，植物多样性呈增加趋势；湿地土壤有机质、全氮含量不断减少，过氧化氢酶、蛋白酶、蔗糖酶活性增加，脲酶活性降低。

在冲积扇缘部位，主要是草甸沼泽土和草甸盐土；由此至沙漠之间，则以盐化和碱化的荒漠土为主，农业利用价值不高。

Habitat utilization of root vole was studied in the region of Haibei Alpine Meadow Ecosystem Research Station, the Chinese Academy of Sciences, from July to September of 2002 and 2003. Three indexes of activity intensities, runway length, runway branch number and burrow entrance number were used to estimate root vole's utilization intensities on four types of habitats, manual cultivated land, true meadow, swamp meadow and Dasiphora fruticosa shrub.

为研究根田鼠对不同类型栖息地的利用强度，于2002-2003年的7-9月在中国科学院海北高寒草甸生态系统定位站地区采用样方法测定了4种类型栖息地（人工耕作地、真草甸、沼泽化草甸、金露梅灌丛）中的3个根田鼠活动强度变量（跑道长度、跑道分叉数、洞口数）。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

The results indicated that there was an ecological succession of wetland plant communities and that the successive series is as follows: aquatic plant→helophytes→swampy prata→herbosa with the changes of habitat from aquatic to mesophytic. The horizonal distribution regularity of plant communities showed symmetric distribution at loop lake or banks of small stream and con centric distribution at depression. The vertical distribution regularity is as follows: aquatic vegetation→moor vegetation→swampy prata vegetation→subalpine meadow subalpine shrub from the center of lake to the hilltop.

结果表明，随着湿地水分由多到少的变化，植物群落类型发生相应的生态演替，其演替序列为水生植被→沼生植被→沼泽化草甸植被→草甸植被，且在水平方向呈对列式和同心圆式分布；从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

It was same that three indexes of activity intensities trended in four types of habitats. The activity intensities of root vole on four types of habitats were in ascending order of the manual cultivated land, true meadow, swamp meadow and D. fruticosa shrub. Three indexes of activity intensities were different significantly between each two types of habitats, except the runway length and runway branch number between the true meadow and swamp meadow.

除了跑道长度和跑道分叉数在真草甸和沼泽化草甸间差异不显著外，3活动强度变量在不同类型栖息地间均差异显著，而且变化趋势一致；根田鼠对4类栖息地的利用强度从大到小依次为金露梅灌丛、沼泽化草甸、真草甸、人工耕作地。
