草原

We analyzed the relations of plant ecological type groups and community biomass and environment changes in the grassland communities of Leymus chinensis as edificator along Northeast China Transect.

初步分析了中国东北样带以羊草为建群种或共建种的草原群落植物水分生态类型功能群生物量及其与群落初级生产力和环境变化的关系。

The study of Elymus sibiricus is important to not only grassland improvement in the northern steppe and Alpine meadow of the Tibetan Plateau but also the development of grassland livestock husbandry.

老芒麦的研究对我国北方草原及青藏高原高寒草甸的退化草地改良、发展草地畜牧业具有重要意义。

Its sensitivity has a great influence on the global climate system. The large-scale rough estimate with the remote sensing data will contribute to the global carbon storage, carbon cycle and the global balance changes. In this study, the NDVI data of the NOAA/AVHRR acquired on 1995 and 2000 were used besides the relevant ground weather data and the eradiate data.

本文计算了1995和2000年的我国陆地NPP，并在此基础上分析探讨了NPP的时间变化以及空间分布特征，并对森林、草原和农作物NPP的数量和时间变化特征进行了统计分析，对引起这种变化的主控因子进行了初步探讨，以增进对我国陆地生态系统NPP的时空格局变化及其控制因子的了解。

Then, soil structure was destroyed and formed erodible particles with size 0.154 to 0.18 mm in the soil surface. Under the impact of strong winds and vehicle wheels, soil erosion by wind and vehicle wheels in soil surface was severe, and some fine particles (≤0.063mm) disappeared gradually, so soil structure would evolve to be coarse.

在车轮的碾压作用下草原土壤表面形成易风蚀粒子（0.154~0.18 mm），受强风和车轮的携带作用后表土风蚀严重，很多细颗粒（粒径≤0.063 mm）在车轮的携带和强风的作用下会逐渐消失，土壤表面进一步向粗粒化发展。

It is an ancient species in its own genus and well-adapted to drought environments with fissurate growth and summer dormancy. Methods We selected Dengkou as our research site and collected three stages of P. mongolica (before, during and after fissuration) during August 1-5, 2002 and 2003. We used PV technique and measured several water relations parameters (φ,φ, ROWC, RWC,△(subscript φ),ε etc. in different stages of fissurate growth for comparison and analysis of drought tolerance and its mechanisms. Important findings Different stages of P. mongolica had different abilities and pathways to maintain turgor pressure. Fissurate growth decreased the species' drought tolerance and involved multiple adaptations to drought.

选取内蒙古磴口县境内具有绵刺群落的草原化荒漠区为研究样区，于2002~2003年每年8月1~5日采集未劈裂、正在劈裂和已劈裂植株，运用PV技术对不同劈裂生长状态绵刺的多种水分关系参数φ(下标 s、φ、ROWC、RWC、△、ε进行了测定，从绵刺保持膨压的能力和途径两方面进行了深入探讨；同时结合同一项目研究中绵刺劈裂生长过程中抗氧化酶系统和内源激素方面的研究成果，综合分析并探讨了绵刺劈裂生长的发生机理及其环境适应性。

P. flagellaria population plots were set in north the Leymus chinensis meadow of Northeast Normal University grassland ecological experiment station. P. anserina population plots were set in Yaojingzi grassland nature reserve of Jilin.

蔓萎陵菜种群样地设在东北师范大学草地生态实验站北甸子羊草草甸群落内；鹅绒委陵菜种群样地设在吉林省腰井子草原自然保护区内。

I couldn't help thanking all the lovelyanimals in nature that have provided enthusiasm and inspiration formy creation.

走遍草原的每个角落，醉心于家乡的兴安石，感恩于自然界可爱的动物们给我的创作激情。

The spunky, fortitudinous heroinentonia, the boundless Nebraska prairie and the struggle of the immigrants in the frontier all greatly impress the reader.

其中的充满活力、坚忍不拔的女主人公安东妮亚，广阔无垠的内布拉斯加大草原以及新移民在边疆的奋斗历程，无不给读者留下深刻印象。

They live on grasslands where they can easily dig up ants, grubs, and worms.

他们还住在草原那里，他们可以很容易挖掘蚂蚁，蛴螬，及蠕虫病毒。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
