草原

The plants on desert steppe exhibited the strongest xeromorphic characteristics, and 3 species of Stipa on the desert steppe had abundant genetic polymorphism.

荒漠草原区的植物是旱生程度最强的一类草原群落，该区的3种针茅具有丰富的遗传多态性。

The relationship between the long-term dynamic of aboveground net annual primary production , aboveground average growth season production and precipitation, and air temperature was analyzed in Stipa klemenzii plant community in NeiMongol Plateau.

研究草原植物群落初级生产力的形成和动态规律是草原生态系统研究的重要内容之一。

The area of Stipa gandis steppe is 2798081hm2 in Inner Mongolia, which is not only the important pasture range in middle-east region, but the main greening proctive screen. It holds an outstanding meaning in the ecology and economy. Based on the morphological characteristics, physiological properties and genetic variation, adaptability of Stipa gandis under grazing pressure were studied.

大针茅是亚洲中部草原亚区特有的蒙古草原种，以大针茅建群的草原在内蒙古的分布面积为 2798081 公顷，这一地区不仅是内蒙古中、东部地区重要的放牧场，也是京津地区的主要绿色屏障，具有不可忽视的生态和经济意义。

The results show that the construction of the railway has an obvious effect on the warm steppe,but the characteristics of community,such as the coverage,ecological dominance and species richness of communities have been improved after its natural restoration,and some species,such as Elymus nutans,Aconitum gymnandrum and Thermopsis lanceolata,play an important role in the restoration communities.An assistant measure taken by human beings will benefit to the restoration.There is no any evidence of exotic invading plants in the restoration of the warm steppe in the study area.

结果显示，青藏铁路修筑过程对铁路两侧一定区域的温性草原有较大影响，但随着受影响区域植被的自然恢复，群落盖度、生态优势度和物种多样性等反应群落特征的指标都有一定程度的改善，一些在原生植被中很少出现或伴生种在恢复后的群落中有可能成为群落的优势种或建群种，如露蕊乌头和鹅绒委陵菜等；人为辅助措施将有利于受损植被的恢复；修筑铁路过程中受到影响的温性草原其恢复过程中尚未出现外来入侵植物。

Based on the scope of aboveground biomass of two main types of steppe vegetation undegraded and degraded, we assessed steppe vegetation degradation rank with the unit of pixel, and compiled steppe degradation distribution map of the middle reach of Xilin River Basin.

以内蒙古锡林河流域中游为研究区，应用Landsat TM资料，结合地面生物量定位测定，建立草原地上生物量估产模型，应用Visual C++编程，估算了2000年7月中下旬锡林河流域中部草原地上生物量。

CH4 uptake, N2O and CO2 emission, have their own relatively fixed seasonal variation patterns in the ungrazed and the grazed grasslands.

禁牧草原及放牧草原吸收CH4、排放N2O和CO2各自有其相对固定的季节变化形式，草原和大气交换温室气体通量的季节变化形式主要受年度气候变化所控制，而土壤、植被类型、降雨量等禁牧因素和放牧强度等人为因素仅影响排放强度。

And nowhere is more impressive than on the veldt of South Africa.

天下最美丽动人的草原非南非的维尔德草原莫属

Most people would know the holodeck as being an invention out of the Star Trek series, but they probably took the idea from a Ray Bradbury short story called The Veldt where a family has a holodeck that simulates an African veldt, and then are eaten by virtual lions.

曾经出现在：大多数人对全息甲板的了解，可能以为它是来自《星际迷航系列》的一个发明。但是，他们很可能是从 Ray Bradbury 写的一个叫《大草原》的短篇小说里得到这个想法的。在这部小说里，一家人有一个全息甲板，能模拟非洲的大草原，然后他们被虚拟的狮子给吃掉了。

Eventually, of course, they did end; beyond lay Nabban, Pirranos Bay and its islands, and the marshy Wran country... all places Simon had never seen and most likely never would.

当然，最终，草原还是会到它的尽头的；在这草原的尽头，是Nabban，Pirranos 港湾和群岛，还有Wran这个沼泽国家——所有这些地方，Simon都没有去过，估计永远也不可能去。

Artemisia intramongolica is a kind of dominant shrub on sandy land in the typical grassland area o our country. It has been suitable to the hot and xeric habitat on sandy land for a long time and has formed series of characteristics that are adaptive to its habitat.

褐沙蒿是分布于我国典型草原带沙地中的优势灌木，由于长期生长在草原区沙地高温、干旱的环境中，形成了一系列与环境相适应的生物学特性。
