In view of Helan Mountain-Yinchuan basin is a ecological Continuum, it's innovative to put forward the holistic system of Helan Mountain-Yinchuan Basin as suitable scale for landscape management. Based on the fact that Helan Mountain-Yinchuan Basin in a circle composed by deserts and Loess Plateau,and seven vegetation ( the mountain forest belt,mountain shrub-grass belt,mountain foot desert grassland belt,oasis belt in diluvial fan plain,oasis belt in alluvial plain,wetland belt near the Yellow river, desert grassland belt in Obrdos platform) belong to the system, a"mountain-plain oasis-river-platform eco-productive paradigm"is proposed.

基于贺兰山——银川盆地是一个生态连续的复合系统，创新性地提出以整个山盆系统做为景观整体管理的尺度；基于贺兰山——银川盆地处于生态脆弱圈内山地森林带、山地灌草带、山麓荒漠草原带、洪积平原带、黄河冲积平原带、黄河滩涂湿地带、鄂尔多斯台地荒漠草原带等7个植被带的水平和垂直地带性特点，提出了贺兰山——银川盆地系统山地-平原绿洲—黄河—台地的生产生态范式。

The western part has broad grasslands, densely-covered marshes, large area of everglade, rich resources of wind electricity and petroleum, affluent ground waters and passing water and good light and heat conditions. It is an important base for various grains and beans, oil plants, sugar plants and livestock and poultry products.

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。

Through analyzing the advantage and problems of ecology, grassland, farmland, water, wetland, woodland, sandlot and rural ecological environment in the west of Jilin province, we pointed out the countermeasures.

通过分析吉林西部的生态、草原、农田、水、湿地、林地、沙地、村落生态环境等几方面的优势和存在的主要问题，提出了相应的对策。

Chagan Lake Tourist Resort is designed to be an ecological tourism center which is characterized by big lake and wetland, grassland scenery and Mongolian folk custom.

查干湖旅游度假区的设计是一个生态旅游中心，其特点是大湖泊和湿地，草原风光和蒙古族民俗。

With distance from the lake,the Aerxiaote lake vegetation happened converse succession.From outside to inside,the structure of plant community was gradually simple,biological diversity was shrinking and halophytic vegetation had decreasing tendencies.From outside to inside,there were Aneurolepidium dasystachys,Phragmites australis,Suaeda salsa L.community.Succession tendency was from wetland and typical grassland vegetation to salinization and desertization vegetation.

阿尔肖特湖边的植被随着距湖面距离及地形的不同，植被发生逆向次生演替，自外向内具有植物群落结构逐渐简单，生物多样性逐渐降低、盐生植物逐渐增加有规律性变化趋势；植被由外至内依次形成了赖草、芦苇、白刺和盐地碱蓬群落梯度，其演替趋势是由湿地和典型草原植被向盐碱化和荒漠化植被过渡。

Semi-trailer is usually running on such roads as soil and sand road,mountain and forest in vertical and latera directions road,grass and wet land.
